PG | 2Vice-Chancellor’s Report
Queensland Brain Institute Annual Report 2010Vice-Chancellor’s ReportThe University of Queensland is continuingto further its reputation as a researchcentre of global significance, and no partof the university more strongly reflectsthat standing than the Queensland BrainInstitute (QBI). With high-quality infrastructure,leading researchers from across the globeand a host of the country’s most talented andcapable students, QBI has truly taken its place onthe world stage since its inception in 2003.As you will see detailed in the pages that follow,innovative research is one of the hallmarksof the Institute – as is, increasingly, internationalcollaboration. In this year, perhaps morethan any other, QBI has built partnerships withother leading neuroscience research institutesacross the globe. Chief among these wasthe announcement of a partnership with theInstitute of Biophysics (IBP) at the ChineseAcademy of Sciences in Beijing, supported by a$1 million National and International ResearchAlliances Program (NIRAP) grant from theQueensland Government. This world-first jointlaboratory is intensifying efforts to identifywhat causes disorders such as ageing dementiaand depression, which remain among the mostsignificant health challenges of our time.As the major centre for neuroscience at TheUniversity of Queensland, QBI also helpedthe University to secure the top rating of fivein neurosciences in the recent Excellence inResearch for Australia (ERA) assessment, which isdesigned to assess research quality across manydifferent fields of research within Australia’shigher education institutions. The University ofQueensland was one of only three institutions toreceive the maximum possible rating for neurosciences.This result highlights QBI’s consistentlyhigh standard of neuroscience research, as therating is characterised by evidence of outstandingperformance well above world standards and isjudged on research quality, volume and activity,application and recognition.An independent review into operations at QBIundertaken during the year has further confirmedthe Institute’s outstanding performanceon a range of key targets. The review wasconducted as part of an agreement establishedin 2008 between the State Government andThe University of Queensland to fund QBI’soperational costs of $25 million over five years.The review panel described the growth of theInstitute, along with its positive contribution tothe reputation, status and economic standing ofQueensland, as “exceptional against most of themetrics”.During 2010, QBI maintained a substantial cohortof students undertaking PhD or MPhil degrees.Coming from a diversity of countries, 28 of themwere international students, attracted by theInstitute’s enviable reputation. QBI’s desire tonurture the next generation of neuroscientistscan also be demonstrated via its pivotal role inthe annual Australian Brain Bee Challenge, whichthis year attracted record numbers of high schoolentrants.In summary, it has been a year of outstandingdiscovery and real-world breakthroughs. Icongratulate Perry and all staff and studentson the accomplishments of this year, and lookforward to following them as they enter thenext exciting phase in their mission to betterunderstand the human brain.Professor Paul Greenfield AOVice-ChancellorLeft: Professor Paul Greenfield AO, Vice-Chancellor with Professor Deborah Terry,Deputy-Vice-Chancellor (Academic).

Director’s ReportThough neuroscientific discovery can bea slow and, at times, painstaking process,2010 proved to be another productiveyear as QBI concluded its seventh yearof operation. Researchers have continuedto build upon findings of previous years,uncovering fresh insights into how brainfunction is regulated which is, in turn, expectedto lead to ground-breaking therapies for arange of neurological and mental illnesses. Inthese endeavours, we remain cognisant thatthe world-renowned research being conductedat the Institute is only possible because of theongoing financial support of funding councilsand governments, and through the generoussupport of donors. We appreciate thepartnership provided by our myriad supporters.Among the advances highlighted in this year’sreport are the discovery by Professor JohnMcGrath that babies with low vitamin D levelswere twice as likely to develop schizophrenia inlater life, a finding which may ultimately informpre-natal health care recommendations; investigationsby Assoc. Professor Bruno vanSwinderen into the attention span of fruit flies,the outcome of which may promote better understandingof attention-deficit hyperactivitydisorder (ADHD) and autism in humans; and,for the first time in humans, the pinpointingby Dr Oliver Baumann of a region of the brainthat is sensitive to navigation and directionPG | 4
Queensland Brain Institute Annual Report 2010Director’s Reportand thus acts like a compass. In January, leadinginvestigator Professor Justin Marshall joined QBIfrom UQ's School of Biomedical Sciences, and hascontinued his fascinating work into how animalssuch as reef fish and birds communicate withcolour and signals outside the range visible tohumans.As part of our mandate to translate discoveriesinto practical applications, QBI established theScience of Learning Centre in June. The Centreis focussed on discovering the mechanismsunderlying learning, and translating thosefindings into effective strategies for teachingboth children in the classroom and adults inthe workplace. Eventually, up to 20 QBI neuroscientistswill work with educators, psychologistsand other scientists in the interdisciplinaryCentre, which is funded by the Institute and TheUniversity of Queensland. QBI is continuing toseek state and federal government funding forthe project.Plans for a Centre for Ageing Dementia Researchare also flourishing. The Centre, due to officiallyopen in 2011, will focus on developing revolutionarytherapies that regulate the death andregeneration of neurons within the adult humanbrain. Early animal research at QBI has shownpromising results which indicate that processeslike neurogenesis may reverse cognitive declineassociated with ageing. Within five years, QBIhopes to have defined the molecules andprocesses which regulate neurogenesis and beapproaching clinical trials and is currently seekingadditional funding support to facilitate suchdiscovery.Against this backdrop of continuing growth anddiscovery, I would like to take this opportunity tothank all QBI staff and, in particular, congratulatethose whose achievements throughout theyear have been outstanding. Linda Richardswas promoted to full Professor and to PrincipalResearch Fellow within the NHMRC system andformer postdoctoral fellows have established newlaboratories both here at UQ (Mike Piper) and atCharles Sturt University (James Crane, AndrewDelaney and Adam Hamlin) - I wish them greatsuccess. I also wish to farewell Professor DavidVaney who has spent 35 years researching thestructure and function of the retina. He hassubsequently been appointed Emeritus Professorof The University of Queensland, a title whichrecognises an academic’s long and distinguishedservice and expresses the hope that they willcontinue to contribute to university life. I wouldlike to take this opportunity to thank David, onbehalf of all QBI, for his support over the years.We wish him all the best for the new challengesthat await, as he pursues his long-standinginterest in photography – thus still exploringvision but from a different perspective.It is through the hard work of numerous peoplethat QBI has grown and thrived – from a smallgroup of investigators in 2003, through to adynamic neuroscience research facility with26 principal researchers today. All of them arecommitted to sharing their knowledge andtheir findings at regular Institute events, rangingfrom lectures and seminars through to opendays and specialist symposiums. I would liketo express my appreciation to everyone – ourFaculty, postdoctoral fellows, research assistants,students and support staff. I am particularlygrateful to my Deputy Directors for Research,Professor Pankaj Sah, and Operations, Mr JohnKelly, for their support and ongoing commitmentto the success of the Institute. I would also liketo acknowledge Vice-Chancellor Professor PaulGreenfield, Deputy Vice-Chancellor (Academic)Professor Deborah Terry and Deputy Vice-Chancellor (Research) Professor Max Lu for theircontinuing support, guidance and friendship.Professor Perry Bartlett FAADirectorLeft: QBI’s Director Professor Perry Bartlett.

Queensland Brain Institute Annual Report 2010Development Board’s ReportDuring 2010, the Development Boardcontinued to raise awareness of the Instituteand promote the award-winning researchbeing conducted by QBI’s team of dedicatedneuroscientists. In all, it was a year in whichwe consolidated the developments of thepast seven years, with a view to furtherexpanding our vision for the future.Substantial progress was made during the yeartowards the establishment of a centre within QBIdedicated to the development of therapeuticapproaches to treat ageing dementia. In July,QBI hosted a visit by the Hon Mark Butler MP,who, at that time, was Parliamentary Secretaryfor Health, and is now Federal Minister forMental Health and Ageing. We updated himon the substantial existing financial support forthe Centre; and the urgent need to push aheadwith research into a condition that is projectedto affect more than 981,000 Australians by 2050.To formally establish the Centre for AgeingDementia Research, QBI is seeking a $17.5 millionFederal Government contribution, with furtherfunding being sought through philanthropy. Itwas encouraging to note that by the end of 2010,almost $4 million had been pledged by bothsmall and large donors. In particular, we wouldlike to acknowledge the substantial generosityof the Estate of Dr Clem Jones AO, The HelpfulFoundation and G. James Australia Pty Ltd.Behind the scenes, QBI was also engaged incompiling information for a Queensland StateGovernment Review, which was required in orderto ensure continued operational funding. It wasvery pleasing to note that QBI over-performedon every one of the indices and it is hoped thatthis will drive the necessary longer-term fundingfor operational costs.We particularly appreciate the efforts of JeffMaclean for continuing to actively promotefundraising activities throughout the year toraise funds for motor neuron disease throughthe Ross Maclean Fellowship.I thank my fellow Development Board membersfor their ongoing support and commitment tothe Queensland Brain Institute, and to ProfessorPerry Bartlett for his leadership and vision. I lookforward to the continued growth of the Institute,and the enhanced possibility for breakthroughsin our understanding of brain functioning thatthis will allow.David MersonChair, QBI Development BoardRight, Board Members from left to right, top down: David Merson, Paul Greenfield, Bob Atkinson,Mark Gray, Sallyanne Atkinson, John Lyons, Perry Bartlett, Jeff Maclean, Milton DickPG | 7

Working out ofa $63 million state-of-the-art centre, researchershandpicked from across the globe along with ahost of high calibre students have demonstratedthe Institute’s commitment to improving thelives and health of everyday Australians.Research at QBI aims to create an environmentof discovery that will ultimately lead to thedevelopment of much-needed therapeutictreatments for neurological disorders andneurotrauma. Indeed, the diverse discoveriesmade during 2010 have reaffirmed the valueof this approach, proving once again thededication of the Institute’s researchers.Christine Dixon undertakespatch clamping procedures.PG | 9
Queensland Brain Institute Annual Report 2010All in the MindNeuroscientistsat theQueensland BrainInstitute haveuncovered howantidepressantsstimulate thebrain to improvea person’s mood– however their research has also found thatnot all antidepressants work in the same way.They discovered the class of drugs thatincreases levels of a neurotransmitter knownas norepinephrine triggers neurogenesis in thehippocampus, which is the area of the brainresponsible for learning and memory.Neurogenesis, or the growth of new neurons,is seen as vital in warding off neurologicaldisorders such as dementia.Lead researcher Dr Dhanisha Jhaveri explained:“If you block hippocampus neurogenesis, antidepressantsno longer work. That suggestsantidepressants must up-regulate neurogenesisin order for them to actually have any effect onbehaviour.”However, the neuroscientists found the resultswere not mirrored with all antidepressants.Surprisingly, the class of antidepressants thatincrease levels of the neurotransmitter calledserotonin (Prozac is a common example) fails tostimulate neurogenesis.Dr Jhaveri explained: “Norepinephrine isbasically binding directly onto the precursorswhich then initiate a signal which leads to theproduction of more neurons.“Serotonin just doesn’t do that. Prozac doesn’twork by regulating the precursor activity – itmay work outside that region, but it isn’tregulating the hippocampus directly. Moreresearch is needed to find out what serotoninactually does.”The team, which is part of QBI’s neural plasticitylaboratory, used rodent models to establish thatselectively blocking the re-uptake of norepinephrinedirectly activated hippocampal stem cells.In turn, they discovered a much larger pool ofdormant precursors in the hippocampus thanwere previously thought to exist.Further, the research expanded existing understandingof the mechanisms by whichnorepinephrine activated the precursors in thehippocampus. It found that the expression ofβ3 (beta-3) adrenergic receptors is critical inmediating the effect.Armed with this information, the team cannow explore improved treatments for seriousneurological disorders, such as depression andageing dementia.“Since dementia – especially in the ageingpopulation – appears to be related to a decreasein neurogenesis this discovery opens up excitingnew ways to stimulate the production of newneurons to alleviate the devastating effects ofdementia in our society,” said Laboratory Headand QBI Director Professor Perry Bartlett.The findings will also allow researchers todevelop more specific – and therefore moreeffective – antidepressants.“Depression is a complex disorder, so we aregoing to test different behavioural outcomesto see whether the compounds that increasenorepinephrine levels or stimulate β3 adrenergicreceptors work only for certain aspects ofdepression. We just don’t know yet but it may,for example, improve learning and memory, orreduce anxiety,” Dr Jhaveri said.The research was conducted by Professor PerryBartlett, Drs Dhanisha Jhaveri, Sanjay Nandamand Adam Hamlin, and Eirinn Mackay (QBI)and Dr Vidita Vaidya and Swananda Marathe(Tata Institute of Fundamental Research, India).The findings were published in the Journal ofNeuroscience in February.Left: A differentiated primary neurosphere derived from norepinephrine-treated adult hippocampal precursorculture contains a large number of βIII-tubulin-positive neurons (pink).

Queensland Brain Institute Annual Report 2010Lord of the FliesThe worldaround us can beoverwhelming– just ask theQueensland BrainInstitute’s Assoc.Professor Brunovan Swinderenwho investigateshow the brain pays attention.The cognitive and behavioural neuroscientisthas discovered a way to measure the attentionspan of a fruit fly, which could lead to furtheradvances in the understanding of attentiondeficithyperactivity disorder (ADHD) andautism in humans.Combining genetic techniques with brainrecordings, researchers found differentmutations can either increase or decrease afly’s attention span. Interestingly, all of thesemutations produce learning and memoryproblems.Using the genetic fruit fly model Drosophilamelanogaster, lead researcher Assoc. ProfessorBruno van Swinderen found that a fly’s level ofdistractibility is finely tuned to allow ‘normal’behavioural responses to a constantly changingenvironment.“We now have the two ends of an attentionspectrum in our model. We have a fly memorymutant that is hard to distract and another flymemory mutant that’s too distractible.“They both have the same result – they don’tlearn well but for completely different reasons,not unlike human patients afflicted with autismand ADHD,” Assoc. Professor van Swinderensaid.“You need a certain amount of distractibility tobe able to assimilate your world – concentratingtoo much or too little affects your ability toprocess and retain information.”Understanding the processes regulatingattention and memory in the fly brain will allowresearchers to better understand how memoryand attention work together to governbehaviour.“One question I’m really interested in is, howdo perceptual suppression mechanisms work?How does the brain ‘block’ you from seeing theworld – what are the actual mechanisms thatprevent you from responding to distractingstimuli, for example? I really think that’s beenoverlooked,” he said.Throughout the research, Assoc. Professor vanSwinderen fed the Drosophila methylphenidate,which is sold under the brand name Ritalin andused to treat children with ADHD. He found thedrug had similar affects on fruit flies as it didon people: it helped the distractible flies to payattention to visual stimuli.“It suggests there may be similar pathways in thebrains of fruit flies and humans, which meanswe now have a simple reductionist model, withall the genetic tools that go along with it, to tryto understand exactly what this drug is doing,”he said.“We know that this drug affects differentpathways. Now we can really try to ask howthat translates to other brain phenomena, suchas how neurons talk to one another. It will helpus form the bigger picture.”To help him build that picture sooner, QBIopened the first joint neuroscience researchlaboratory between Australia and China inSeptember. Assoc.

Queensland Brain Institute Annual Report 2010Common Scents ApproachEvery momentof every day thebrain is forcedto processthousandsof separateodorants fromthe world aroundus.Through the study of honeybees, scientists atthe Queensland Brain Institute have discoveredthe brain has an advanced ability to isolatespecific odorants and recollect smells.“There’s a lot of information coming into thebrain whenever a scent is detected and it wouldbe difficult to process it all.“We’ve found that honeybees pick only ahandful of so-called ‘key odorants’ out of everycomplex aroma that they really learn. They mayremember just six or seven odorants from acouple of hundred – the rest are ignored,” saidlead researcher Dr Judith Reinhard.“If you had to learn the hundreds of compoundsyour brain is subjected to every minute ofevery day you would be overwhelmed withinformation. By choosing the key odorants, youcan function more effectively without the brainbeing swamped,” added fellow researcher DrCharles Claudianos.The research has also allowed the scientists toexplore how the learning of odours is linkedto molecules that have been associated withautism and schizophrenia.Dr Claudianos explained: “These synapticmolecules connect neurons and help wire thebrain correctly. If the molecules are out ofbalance, as is the case in autism and schizophrenia,odour processing goes haywire. Peoplewith these neurological disorders perceivesmells differently, which can be used for earlydiagnosis.”During their studies, the researchers foundthat the honeybee brain responds to sensoryexperience.“The honeybee brain – like the human brain –adapts to its sensory environment by adjustingthe expression of molecules involved in odourdetection.“It is a complex process and we do not yet fullyunderstand it, but it seems that the brainincreases or decreases expression of thesemolecules, depending on what scents areout there, to optimise odour detection,” DrReinhard explained.The findings could also have an enormousimpact on Australian farming. Scientists will beable to isolate key odorants from the complexaromas of crops and then use these to trainhoneybees to pollinate specific harvests.“Farmers often have problems makinghoneybees focus on the crop – the bees goastray and go to nearby forests or nationalparks and the farmers don’t get a good yield,”Dr Reinhard said.“If we know the key odorants of the almondaroma, for example, we could use these totrain the honeybees in the hive to focus only onpollinating almonds. Then you’d have a muchhigher likelihood the honeybees would stay inthe crop and pollinate it.”The next step for scientists is to determinewhether humans use the same technique oflearning specific key odorants so our brain is notoverwhelmed by too much sensory information.Early research suggests we do.“If we can confirm that humans use the same keyodorant technique as honeybees, it would meanthat we have discovered a general strategy ofscent processing,” Dr Reinhard said.The findings were published by QBI’s DrsReinhard and Claudianos, Professor MandyamSrinivasan and Mr Michael Sinclair in PLoS Onein February.Above: Almond blossoms.

Queensland Brain Institute Annual Report 2010Shining Light on SchizophreniaSunshine has longbeen seen as vitalfor healthy bones– now QueenslandBrain Instituteresearchershave found alink betweennewborn babieswith low levels of vitamin D and an increasedrisk of schizophrenia.Using tiny blood samples from Denmarknewborns, the team compared vitamin D concentrationsin babies who later developed schizophrenia,with healthy controls – and confirmedthose with low vitamin D were twice as likely todevelop the disorder.Vitamin D, or the ‘sunshine hormone’, isthe result of sunshine on the skin, howeverdeficiency is common in many countries.“Although we need to replicate these findings, thestudy opens up the possibility that improvingvitamin D levels in pregnant women andnewborn babies could reduce the risk of laterschizophrenia,” Professor John McGrath said.Schizophrenia is a poorly understood group ofbrain disorders that affects about one in 100Australians, and usually first presents in youngadults.Findings from the three-year study couldeventually inform public health messages, inmuch the same way that pregnant women areencouraged to increase folate to reduce the riskof spina bifida in their children.However, it is not just this research that isbeing heralded – the techniques used by theresearchers have also garnered internationalattention.As the blood samples available were exceptionallysmall, scientists had to develop a new way totest – or assay – vitamin D levels.“It took three years of hard work but we haveprobably developed the world’s most sensitiveassay for vitamin D,” fellow investigator DrDarryl Eyles explained.The assay has been so effective it is now beingused by scientists researching cancer, diabetes,multiple sclerosis, autism and asthma.Meantime, in a separate project, ProfessorMcGrath found that young adults who usecannabis from an early age are three times morelikely to experience psychotic symptoms.The study of more than 3,800 21-year-olds, bornat Brisbane’s Mater Hospital, revealed those whouse cannabis for six or more years have a greaterrisk of developing psychotic disorders or theisolated symptoms of psychosis, such as hallucinationsand delusions.The research included the results of 228 sets ofsiblings.“Looking at siblings is a type of naturalexperiment – we found the same links withinthe siblings as we did in the entire sample, whichmakes the findings even stronger.“The younger you are when you start to usecannabis, the greater the risk of having psychoticsymptoms at age 21,” Professor McGrath said.The research appeared in the Archives of GeneralPsychiatry in March, with researchers fromQBI, UQ’s Department of Psychiatry, Centre forYouth Substance Abuse Research and School ofPopulation Health, the Queensland Centre forMental Health Research, the Royal Children’sHospital, Princess Alexandra Hospital, MaterChildren’s Hospital and the University of NewSouth Wales.The research into the increased risk of schizophreniain people with low prenatal vitamin Dwas carried out by QBI’s Professor McGrath, DrsEyles and Tom Burne, Mr Cameron Andersonand Ms Pauline Ko, with colleagues from theUniversity of Aarhus, Denmark, and the StatensSerum Institut, Denmark. It was published in theArchives of General Psychiatry in September.Above: Professor John McGrath.

Queensland Brain Institute Annual Report 2010Navigating a path for improved diagnosisIf you have everlost your senseof direction in anunfamiliar placethen QueenslandBrain Instituteresearchers maybe able to help.They havediscovered a neuronal population sensitive toheading direction in humans. Head directionsensitive cells have been found in rodents, butevidence for such cells in humans had beenlacking.Lead researcher Dr Oliver Baumann askedvolunteers to learn the directions to landmarksaround a computer-generated maze overseveral days. He then measured the volunteers’brain activity as they viewed each of thelandmarks in isolation.“The brain acts like a compass, with differentneurons firing depending on the directionpeople think they are heading. We certainly donot have a magnetic sense, but we have a brainregion that nevertheless codes the direction weare heading in,” Dr Baumann explained.“Our study provides not only the first evidenceof a brain region sensitive to heading directionin people, but also its precise location in thebrain.”The researchers used functional magneticresonance imaging to monitor people’s brainactivity as they carried out the computerisedtesting.They found that a small area in the parietalcortex, located toward the back of the brain,provides critical details for navigation andinformation about the direction in which aperson is heading.“Here we have evidence in a normal, healthyhuman population that there is a dedicatedcluster of neurons that encodes our sense ofdirection,” fellow researcher Professor JasonMattingley said.“If this brain region is damaged it can severelydisrupt a person’s ability to navigate in newsituations. Such damage is common in strokeand Alzheimer’s disease. People haven’t madethis link before – previously it was just aclinical anecdote.”Professor Mattingley predicted clinicianscould eventually use navigational tests, suchas those created for this study, as an earlyprobe for the onset of dementia.“Our research suggests that one of theimportant cognitive functions we should betesting in people with suspected dementia istheir sense of direction,” he said.Dr Baumann added: “The assessment ofnavigational skills in people with suspecteddementia could be more sensitive to earlysigns of Alzheimer’s disease than traditionalscreening tests. Furthermore, performanceon virtual reality navigation tasks could serveas a valuable behavioural marker of diseaseprogression.”There might even be scope to test whethermen’s sense of direction really is better thanwomen’s.It is often suggested that females are poorerat navigation than males, however superiorperformance by men is not found in all tasksinvolving spatial skills.Professor Mattingley said: “Most interestingly,there appear to be qualitative differencesin the environmental cues and strategiesthat women and men use during navigationand orientation. Women typically reportnavigating on the basis of local landmarksand familiar routes, whereas men report usingcardinal directions.”“Our approach could provide an objective testby revealing whether male and female brainsrespond differently during navigation tasks,”concluded Dr Baumann.The research was conducted by ProfessorMattingley and Dr Baumann and appeared inthe Journal of Neuroscience in September.Above: Dr Oliver Baumann.

Queensland Brain Institute Annual Report 2010Discovering Creatures of the DeepPushing theboundaries isan almost dailyrequirement forany scientist.Hence, it is nosurprise that neurobiologistsfromthe Queensland Brain Institute have delveddeep into the Coral Sea to learn more aboutocean life and, in turn, human vision.Using high-tech equipment and instrumentplatforms new to Australia, prehistoric six-gilledsharks, giant oil fish, swarms of crustaceans andmany unidentified fish were caught on camera1,400m below sea level at Osprey Reef, 350kmnortheast of Cairns.The team, led by Professor Justin Marshall,captured the sea creatures using speciallow-light sensitive, custom-designed remotecontrolled cameras, which sat on the seafloor. The Australian Research Council fundedthe equipment that was built at The HarbourBranch Oceanographic Institute in Florida.“Osprey Reef is one of the many reefs in theCoral Sea Conservation Zone, which has beenidentified as an area of high conservationimportance by the Federal Government.Therefore, it is paramount that we identify theecosystems and species inhabiting the area,”Professor Marshall said.“As well as understanding life at the surface,we need to plunge off the walls of Ospreyto describe the deep-sea life that lives downto 2000m, beyond the reach of sunlight. Wesimply do not know what life is down thereand our cameras can now record the behaviourand life in Australia’s largest biosphere, thedeep-sea.”Scientists working on the Deep AustraliaProject also collected amazing footage of theNautilus, a relative of squid or octopus that stilllives in a shell as they have done for millions ofyears.Researchers measured these living fossilsto find out more about their biology beforereturning them to the sea.“Learning about these creatures’ primitive eyesand brain could help neuroscientists to betterunderstand human vision,” research studentAndy Dunstan said.Professor Marshall explained most of ourknowledge on how nerve cells function andcommunicate was first pioneered throughwork on squid giant nerve cells.“We are now returning to these original modelsystems, both for their own intrinsic interestand also to better understand brain disorderswhich lead to conditions such as epilepsy,” hesaid.Deep Australia Project Manager Kylie Greigsaid the expedition helped shed light on howdeep-sea creatures had evolved over time.“This technology will help the discoveryof deep-sea creatures’ adaptations to thechallenges of living at crushing depths and infreezing, dark water. Here they must find foodand mates in the dark and avoid being eatenthemselves.“We are interested in the sensory systems usedfor this lifestyle,” she said.However, to explore the unknowns of thedeep sea, it is vital the creatures are protectedand currently oceans are under threat from avariety of human activities.Contributing to this effort, Professor Marshalljoined with educator Craig Reid, Coral WatchProject Officer Dave Logan and graphicdesigner Diana Kleine to author Coral Reefs andClimate Change: the guide for education andawareness.

Queensland Brain Institute Annual Report 2010ResearchUnlike other research organisations which focus onparticular diseases or conditions, QBI is structuredto study the brain’s fundamental molecular andphysiological mechanisms. Research is conductedacross the seven key themes of cognition andbehaviour, computation and neuronal circuits,neurogenesis and neuronal survival, neurogeneticsand epigenetics, neuronal development andconnectivity, sensory systems and synaptic function.QBI neuroscientists use the world’s most advancedinvestigative technologies for their research, includingflow cytometry and mass spectrometry equipment.They use human volunteers in their research and alsostudy a range of animal models, including the mouse,honeybee, fruit fly, frog, zebrafish and flatworm.Developing visual circuit in a zebrafish brain(six days old). Labelling of nerve fibres in redreveals a 'neural skeleton' in the zebrafishbrain.

Laboratory Head Professor Perry BartlettNeurogenesis, the production of new nerve cells in the adult brain bypopulations of resident stem cells, has been implicated in regulatinglearning and memory. Research to date has suggested that stimulatingthis production may be therapeutic for diseases such as dementia anddepression. To study how various factors released by nerve stimulationactivate stem cells in the hippocampus to produce new nerve cells,members of the Bartlett laboratory are using unique cell-sortingtechnologies to isolate stem cells and novel in vivo techniques.Above: Bartlett group photo. 2010 Laboratory Members: Debra Black, Daniel Blackmore, Lavinia Codd, Michael Colditz, Kirsty Dixon, Dhanisha Jhaveri,Vilija Jokubaitis, Masahiro Kameda, Tamara Koudijs, Li Li , Eirinn MacKay, Estella Newcombe, George Rigley, Gregory Robinson, Sumiti Saharan, JaySpampanato, Mark Spanevello, Sophie Tajouri, Chanel Taylor, Jana Vukovic, Tara Walker, Dianne Walker, Di Xia. Above right: Neurosphere from an aged(24 month) mouse demonstrating that neural stem cells within old animals retain the ability to produce neurons (in red) and astrocytes (green).PG | 26Stimulating neurogenesis in the brainDuring 2010, the laboratory continued toinvestigate the regulation of neurogenesis inthe brain, with the specific aim of discoveringmolecules that activate resident precursor cells.During the year, the team discovered a secondpopulation of precursors in the hippocampusthat are normally dormant, but can be activatedby the neurotransmitter norepinephrine (NE)to produce new nerve cells both in vitro andin vivo. Furthermore, we demonstrated thatNE acted directly on the precursor populationthrough a beta-3 adrenergic receptor, definingfor the first time a mechanism of action for theclass of antidepressants that raise NE levels.Previously, it has been posited that antidepressantsthat raise NE or serotonin levels mayact by increasing neuronal production in thehippocampus. Our studies show that onlyNE directly regulates this, suggesting thatserotonin may act indirectly or through raisingNE levels. These discoveries present new opportunitiesfor developing antidepressantswhich target the beta-3 receptor.Also, the finding reveals that there is morethan one population of precursors in thehippocampus, since the NE-activatedpopulation is quite separate to the onewe previously described in 2008, whichwas activated by synaptic activity. Thus, itappears that there are discrete populations ofprecursors which respond to different stimuli,raising the possibility that they may give rise topopulations of neurons with subtle differencesin their synaptic machinery, which may explainwhy different stimuli lead to different hippocampal-dependentbehavioural outcomes. Thispossibility is now being investigated.Coronal section of a transgenicmouse brain showing Thy1 positiveneurons. Image Sophie Tajouri.
Laboratory Head Dr Timothy BredyDr Timothy Bredy’s laboratory is interested in elucidating how the genomeis connected to the environment, and how this relationship shapes brainand behaviour across the lifespan. In contrast to the information conveyedby a static genome, the epigenome is very dynamic and can be modifiedby exposure to a variety of environmental stimuli, including learning,exposure to drugs of abuse, environmental toxins, dietary factors andsocial interaction.1Original Memory2Memory RetrievalNewInformationPG | 28Above: Bredy group photo. 2010 Laboratory Members: Kevin Dudley, Carlos Coelho, Wei Wei, Xiang Li , Danay Baker-Andresen, Vikram Ratnu, RogerMarek, Zoran Boskovic, Maria Galeanos, Joanne Loh, Zhanzhi Yan. Above right: The transcription factor ATF4 is coexpressed with the histoneacetyltransferase PCAF within the infralimbic prefrontal cortex.Shaping scientific understanding of epigenetic mechanismsIn 2010, the Bredy group discovered that, inmice, the extinction of conditional fear (aform of inhibitory learning important for thetreatment of anxiety disorders) is regulated bymicroRNA activity in the prefrontal cortex. Wealso demonstrated that there are epigeneticregulatory proteins such as p300/CBP-associatedfactor (PCAF), which are unique to theextinction learning process. We have alsobeen performing genome-wide methylationprofiling experiments to determine whethersex-specific cortical DNA methylationpatterns are associated with sex differences infear-related learning and memory.The year has been a busy one in otherways. Laboratory members organised thefirst Epigenetics, Behaviour and Diseasesymposium, while Dr Bredy delivered invitedtalks at a range of neuroscience events. DrBredy and Dr Kevin Dudley, a postdoctoralfellow, published a review on epigeneticmechanisms mediating vulnerability andresilience to psychiatric disorders.In December, the group welcomed PhDcandidate Ms Danay Baker-Andresen, whoholds a National Science and EngineeringCouncil post-graduate scholarship, fromCanada. We were fortunate to host a summerresearch scholar, Mr Xiang Li, and we alsowelcomed two co-supervised PhD students –Mr Vikram Ratnu with Professor John Mattick,and Mr Roger Marek with Professor PankajSah.Our research associates, Drs Wei Wei and CarlosCoelho, continued to perform extraordinarilyin overseeing experiments and maintainingthe laboratory.

Queensland Brain Institute Annual Report 2010Laboratory Head Dr Thomas BurneThe Burne laboratory studies brain development and behaviour in animalmodels to learn more about neuropsychiatric diseases. Researchersinvestigate the underlying biological basis for schizophrenia, with the aimof finding appropriate public health interventions. The group has beenexploring the impact of developmental vitamin D deficiency on braindevelopment, the impact of adult vitamin D deficiency on brain functionand behaviour, and the neurobiological effects of having an older father.The group is part of the Queensland Centre for Mental Health Research.Above right: Burne group photo. 2010 Laboratory Members: James Kesby, Lauren Harms, Claire Foldi, Carlie Cullen, Natalie Groves, Karly Turner,Suzy Alexander, Meggie Voogt, Pauline Ko, Henry Simila.

We haveexplored the behaviour, brain neurochemistryand receptor profile associated with vitaminD deficiency in animal models. Now the collaborationis investigating the impact of DVDdeficiency on social and cognitive behaviours.Probing the roots of schizophreniaResearch into the impact of adult vitamin Ddeficiency on brain function has also started.The Burne group has also expanded itsresearch tools, with a suite of cognitivebehavioural tasks to assess attentionalprocessing in rodents. The goal now is toinvestigate the neurobiology of alteredcognition in animal models, by looking atselected cognitive domains – sensorimotorgating, working memory, attention andspeed of processing, learning and memory,and problem solving – that are known to bedisrupted in schizophrenia. In collaborationwith other neuroscientists at QBI, we havealso begun to incorporate other species, suchas zebrafish and fruit flies, to ask questions ofthe ‘small brain’. This research made the coverof Molecular Psychiatry.Further, the group published the first comprehensivestudy of the impact of advancedpaternal age in a mouse model on behaviourand brain structure.

Laboratory Head Dr Charles ClaudianosDr Charles Claudianos’ laboratory examines how sensory experience changesnerve cell junctions called synapses that control information transfer in thebrain. There are literally hundreds of genes that encode or regulate proteinsthat contribute to development of synapses – but when these genes aredefective, the synapses fail to transfer appropriate signals and cognitivedisorders may result. To understand how this works in humans, researchersstudy the same molecules in simple insects such as fruit flies and honeybeeswhich have advanced genetic and behavioural toolsets.Above: Claudianos group photo. 2010 Laboratory Members: Zoran Boscovic, Alexandre Cristino, Maria Rondon Galeano, Nevitha Gunasekaran, Yeu LinLiu, Janelle Scown, Sarah Williams, Shan Shi Yang, Zheng-yang Zhao. Above Right: Fluorescent antibody staining of olfactory receptor proteins at the tipof the honeybee antennae.PG | 30Investigating molecular response to sensory experienceDr Claudianos’ team studies neurexin-neuroliginmolecules with regard to sensory acuity,learning and memory and with respect tothe greater network of genes that functionin the brain - the ‘neurome’. Togetherwith QBI colleague Dr Judith Reinhard, thelaboratory discovered neurexin-neuroliginmolecules found in the synapse are regulatedin specific patterns depending on the sensoryexperience. Their research, detailing howassociative memories of odours significantlychanged expression of these molecules in thehoneybee brain, was published in PLoS ONE in2010. Molecular changes occurred whenevera bee learnt new odours, showing that thesense of smell is not hard-wired but remainsplastic throughout adult life. The team alsodiscovered that the brain needs sensoryinformation to develop normally.During the year under review, the Claudianos’laboratory also built upon 2006 researchin which it helped publish the ‘honeybeegenome’. A principal discovery was that thehoneybee had far fewer genes than otherinsects, with Dr Claudianos and his colleagueshypothesising that gene shortfalls associatedwith environmental responses in the beewere due to the evolution of sociality in thebee. In 2010, members of his laboratory werepart of an international team that sequencedthe related ‘wasp genome’, with researchpublished in Science and Insect MolecularBiology. The results showed that the wasp hasa different complement of genes comparedto the bee, supporting the idea that socialbehaviour reduces molecular diversity – whichoffers a lesson for our own human evolution.Soluble honeybee neurexin 1 (Nrx1)protein (green) expressed in monkeyCOS-7 cells is purified and used todetermine biochemical interaction ofsynaptic proteins of neurons.
Queensland Brain Institute Annual Report 2010Laboratory Head Assoc. Professor Ross CunningtonResearch in Assoc. Professor Ross Cunnington’s laboratory focuses on thebrain processes involved in planning and preparing for voluntary actionsand for perceiving and understanding the actions of others. Wheneverhumans plan, imagine, or observe others performing actions, representationsof those actions are encoded in the motor areas of the brain. In 2010,researchers explored brain imaging methods to examine how people formplans for action before initiating voluntary movement, and how our ownplans for action can influence the way we perceive others’ actions.Above right: Cunnington group photo. 2010 Laboratory Members: Marta Bortoletto, Pascal Molenberghs, Katharine Baker, Veronika Halasz, Kian Ng,Vinh Nguyen, Simmy Poonian. Above left: We examine brain processes involved in the perception of observed actions. There appear to be specialisedareas in the human brain that allow us to readily perceive and understand the actions and gestures of others.Using EEG, we can see brain activityincreasing over the mid-line motorareas of the brain as people plan andprepare voluntary movements.Members of the Cunnington laboratoryexamine the chain of brain processes thattransform our intentions into plans foraction that can be executed by the brain’smotor system. Our research has revealedhow activity in prefrontal regions of thebrain, beginning up to one second beforemovement, is important for deciding the rightmoment to initiate voluntary actions. Thisoccurs before activity starts in premotor brainareas involved in coding specific sequences ofmovement to make up complex actions.Researchers are also discovering how thesame brain processes involved in planning ourRevealing secrets of mirroring through brain imagingown actions are also important for our abilityto perceive and understand the observedactions of others. Known as mirroring, thisprocess is thought to underlie the way inwhich we can understand intentions andempathise with others.The laboratory also develops new methodsfor examining human brain activity and itsfunction. In a collaboration with the MedicalUniversity of Vienna, researchers in theCunnington laboratory are using ultra-highresolution brain imaging (7 Tesla humanMRI) to examine neural activity of themotor system during planning. We are alsodeveloping techniques for combining the highresolution of MRI brain imaging with the hightiming accuracy of brain activity recordingswith concurrent fMRI-EEG measurement –allowing us to visualise and examine humanbrain activity in more detail than ever before.The development of Brain-ComputerInterfaces – devices that can read and ‘decode’people’s brain activity as they make choicesbetween items on a computer screen – is afurther exciting extension of this research.With such devices, patients can learn to selectand control objects just by the computerdetecting changes in their brain activity.PG | 33
Laboratory Head Dr Darryl EylesDr Darryl Eyles’ laboratory is primarily focused on modelling non-genetic riskfactors for schizophrenia. This work has greatly enhanced understandingof the effect of vitamin D on a person’s likelihood to develop schizophrenia.Most noticeably, research in animal models has demonstrated that adevelopmental vitamin D deficiency in newborns increases the chances ofdeveloping the disorder in later life. Further, work from this group has firmlyestablished that vitamin D regulates brain development. The group is partof the Queensland Centre for Mental Health Research.Above: Eyles group photo. 2010 Laboratory Members: Xiaoying Cui, Trudi Flatscher-Bader, Isabel Formella, James Kesby, David Kvaskoff, Pauline Ko,Henry Simila, Suzy Alexander, Karly Turner, Ashley Liu, Maggie Voogt, Lauren Harms, Claire Foldi, Elizabeth Mason, Jennifer Goddard, Karthic Purushothaman,Jacqui Byrne, Ben Calcagno.

Research hasshown direct reductions in specification andmaturation factors for dopaminergic neuronsin foetal DVD-deficient brains, which correlatewith disturbances in brain function both at thelevel of locomotion and selective attention.The group is rewriting the paradigm thatdopamine may not represent a final commonpathway for schizophrenia. Rather, it maybe the initial common abnormality in braindevelopment that precipitates the multipledisturbances seen in other neurotransmittersystems in this disorder. Currentlyresearchers are modelling how alterations indopamine levels affect brain developmentand behaviour in models such as zebrafish,fruit flies and mosquitoes. The use of avariety of model animals continues to providea diverse and flexible research platform inunderstanding the neurobiology of seriouspsychiatric disease.In clinical research, the Eyles laboratoryhas developed possibly the world’s mostsensitive test for 25 hydroxyvitamin D, whichcan detect tiny amounts of this vitamin inpaediatric dried blood spots. Apart frombeing successfully used to indicate that lowvitamin D levels are associated with schizophreniain later life, this test is now being usedin the laboratory to assess the vitamin’s role inautism, cancer and multiple sclerosis.Dopamine neurites innervating thecentral complex and mushroombodies of a fruit fly (Drosophilamelanogaster).
Queensland Brain Institute Annual Report 2010Laboratory Head Professor Geoffrey GoodhillResearch in Professor Geoffrey Goodhill's laboratory uses a uniquecombination of experiments and theoretical modelling to develop acomputational understanding of how the nervous system becomes wiredup during development. For the brain to function properly, its neuronsmust be connected correctly. The laboratory’s guiding philosophy is thatbuilding mathematical models allows a much more precise understandingof the underlying phenomena than relying on purely qualitative reasoning.Above right: Goodhill group photo. 2010 Laboratory Members: Zac Pujic, Andrew Thompson, Jiajia Yuan, Clement Bonini, Jinjun Sun, Stanley Chan,Duncan Mortimer, Jonny Hunt, Clare Giacomantonio, Hugh Simpson, Richard Faville.Above left: Rat neurons growing in a microfluidic chamber.4000 photos grouped into clusterswhich share similar statistical properties,providing insight into the brain'svisual function.Using mathematical models to identify neural wiring defectsOne area of focus for the Goodhill laboratoryis how nerve fibres (axons) are guided bymolecular gradients to find appropriate targetsin the developing nervous system. Onesurprising result recently was that the responseof axons to shallow gradients is different fromtheir response to steep gradients – not onlyquantitatively but also qualitatively. Thishelps explain apparent anomalies betweenresults from different gradient assays and alsoprovides an insight into the way axons areaffected by gradients in vivo.Researchers have also investigated the formand shape of growth cones, the structures atthe tip of developing axons. This morphologyis complex and highly dynamic but thesignificance of these changes for either thesensory or motor roles of growth cones ismostly unknown. As such, sophisticatedmathematical techniques for characterisingshape in general are currently being adaptedin order to develop a more quantitative understandingof the role growth cone shape plays ineffective axon guidance.Further, the Goodhill laboratory is studyingvisual system development, particularly mapsin the primary visual cortex. Visual maps(and thus visual function) are affected by thestatistics of visual input during early life, butteasing apart the relative contributions of input-dependentmechanisms of developmenthas proved an extremely challenging task.Researchers have investigated the effect ofrestricting visual input early in life on visualdevelopment. Their theoretical predictionssuggest that a surprisingly large degree ofvisual map structure plasticity may be possible– a theory now being tested by experimentalcollaborators.PG | 35
Laboratory Head Dr Massimo HilliardDetermining how individual neurons develop is crucial for understandinghow highly complex neuronal structures, such as the brain and spinalcord, are formed. Dr Massimo Hilliard’s laboratory is interested inunderstanding how axons (nerve fibres conducting impulses from theneuron) and dendrites (nerve processes conducting impulses to theneuron) develop and how they are guided to their targets. The group alsoinvestigates how the axonal structure is maintained over time and how itcan be reconstituted after injury.Above: Hilliard group photo. 2010 Laboratory Members: Sean Coakley, Leonie Kirzsenblat, Jujiao Kuang, Casey Linton, Brent Neumann, DivyaPattabiraman, Katherine Truong, Nick Valmas.

Image Leonie Kirzsenblat.PG | 36Unlocking secrets of axonal growth and regenerationNeurons are among the most highly polarisedcells in the body, with their dendrites and axonsforming distinct morphological and functionaldomains. However, the understanding ofhow dendrites develop is poor, with only afew molecules known to play a role in thisprocess. Using the nematode – or roundworm- Caenorhabditis elegans as a model system, theHilliard group has identified two Wnt ligandsand two Frizzled receptors that regulatedendrite development in vivo.The axon protruding from a neuronal cell canextend extraordinarily long distances, withmechanisms in place to maintain the structuralintegrity of these long processes over theanimal’s lifetime. Failure in the maintenanceof the axonal process is one of the underlyingcauses of different neurodegenerativeconditions including motor neuron disease.Using forward genetic screens, researchersin the Hilliard group have identified mutantanimals in which the axons of C. elegansmechanosensory neurons and oxygen sensoryneurons spontaneously degenerate. Thegroup now seeks to identify the mutated genesresponsible for this condition, and to identifyaxonal degeneration phenotypes in motorneurons.A crucial question for neurobiologists is howsome axons can regenerate following nervedamage while others cannot. The answer willbe of great value in the treatment of neurodegenerativeconditions and traumatic nerveinjuries. Using a laser-based technology toaxotomy single neurons in living C. elegansanimals, the Hilliard laboratory has shown thataxonal regeneration can occur by a mechanismof axonal fusion, whereby the two separatedaxonal fragments can specifically re-attach andrestore the original axonal tract.Axonal degeneration in a C. elegansmechanosensory sensory neuron.Image Brent Neumann.

Collectively, the grouphas produced more than 25 publicationsthis year, including a book, contributionsto Current Biology and two major editedreviews. This output effort from laboratorymembers and international collaborators isoutstanding and several of our papers havealso been highlighted in Science, Nature andNew Scientist. Recognising the importanceof communicating science beyond scientists,the work of the laboratory has also featuredin international non-science media for workon visual systems and deep sea, including SirDavid Attenborough’s latest documentaryFirst Life and TIME Magazine.The way in which the ultraviolet (UV) region ofthe spectrum and other colours are used by avariety of animal communication systems is amajor component of the Marshall laboratory’swork.

Queensland Brain Institute Annual Report 2010Laboratory Head Professor Jason MattingleyAttentional processes are crucial for virtually all cognitive functions inhumans, including learning and memory. A long-standing question is howthe brain selects just a few important inputs from myriad sensory datawhile filtering out irrelevant elements – in other words, how it regulatesmechanisms of attention. Professor Jason Mattingley’s team seeks toanswer this by using cutting-edge brain imaging and brain stimulationtechniques, including functional magnetic resonance imaging (fMRI),electroencephalography (EEG) and transcranial magnetic stimulation (TMS).Above right: Mattingley group photo. 2010 Laboratory Members: Oliver Baumann, Luca Cocchi, Marc Kamke, Pascal Molenberghs, Martin Sale, DavidLloyd, Edgar Chan, Michael Dwyer, Veronika Halasz, Will Harrison, Oscar Jacoby, Inga Laube, David Painter, Amanda Robinson, Daniel Stjepanovic,Lydia Hayward.

Red crosshairs indicate a brain region involved in attention.Dr Marc Kamke applies TMS to testthe involvement of different brainareas in selective attention.In 2010, researchers in the Mattingley laboratorycontinued to investigate the brain processesthat regulate selective attention in healthand disease. Mr David Painter, a PhD student,has recently developed a novel approach tomeasuring changes in brain activity that occurwhen attention is deployed over complex andrapidly changing visual displays. The protocoluses EEG recorded from the scalp to measuretiny fluctuations in the brain’s electrical activity.During these recordings, volunteers focustheir attention to locate coloured targetsamong flickering, multi-coloured distractors.By analysing precisely timed oscillations inthe brain’s activity, the researchers discoveredAnalysing and understanding attentional processesunique signatures for sensory events that areattended and ignored – effectively showinghow the human brain sorts the wheat from thechaff.Having learned more about how attention iscontrolled in the healthy brain, the researchersare now using their novel tests to examineimpairments of attention in patients with braindamage due to stroke. The same approachwill also be used to assess the efficacy of newbehavioural and pharmacological treatmentsfor perceptual and cognitive deficits in a rangeof neurological disorders.Other work being pursued by the team hasfocused on neural plasticity, the brain’s capacityto undergo functional alterations in responseto external stimulation or learning. Using TMS,work conducted by research fellows Dr MarcKamke and Dr Martin Sale discovered thatmechanisms of attention regulate plasticity inthe primary motor cortex in healthy volunteers.The next step for the team will be to determinewhether the influence of attention on plasticityholds for brain areas outside the motor system.Armed with this knowledge, they hope to beable to develop more effective approachesfor the rehabilitation of sensory and motorimpairments following stroke.PG | 39

In the absence of majortreatment advances, interventions that offerthe prospect of reducing the incidence of thedisorder should be vigorously pursued.Professor John McGrath’s group, whichforms part of the Queensland Centre forMental Health Research, has discovered alink between early life vitamin D levels andrisk of schizophrenia. Working with Danishcollaborators, the McGrath group usedblood samples from newborn babies toconfirm a deficiency in neonatal vitamin Dlevels is linked to a higher risk of developingschizophrenia. If future studies confirm theassociation between developmental vitaminD deficiency and a higher risk of schizophrenia,than it could raise the prospect of primaryprevention – much like folate supplementationto prevent spina bifida.Based on a large US birth cohort, researchersin the McGrath laboratory also found that theolder the father, the more likely his childrenwere to have impaired brain development.The offspring of older fathers also have aslightly increased risk of schizophrenia andautism. While it has long been recognisedthat maternal age is linked to conditions suchas Down syndrome, paternal age has beensomewhat neglected. The researchers are nowpart of a collaboration further examining theissue in a mouse model. Group researchers DrTraute Flatscher-Bader and Claire Foldi havealso been exploring behavioural, genomicand brain imaging in a mouse model relatedto advanced paternal age.

Queensland Brain Institute Annual Report 2010Laboratory Head Assoc. Professor Frederic MeunierNeurons are highly polarised cells that transport membrane compartmentscalled organelles. They underpin functions like neuronal communicationthrough the release of neurotransmitters at the synapse and carry importantsurvival factors from the synapse back to the cell body. The Meunierlaboratory is designing fluorescent probes and live cell microscopy which,when combined with proteomics, electrophysiology, structural biology andbiochemistry, will enhance understanding of the molecular mechanismsunderpinning different forms of neuronal membrane trafficking.Above right: Meunier group photo. 2010 Laboratory Members: Tam Nguyen, Shona Osborne, Sally Martin, Regine Low, Peter Wen, Rachel Gormal,Nancy Honesta T Malintan, Vanesa Tomatis , Callista Harper , Guillaume Maucort.

EMBO Jwith permission.Resolving puzzles of neuronal trafficking and communicationIn 2010, the Meunier laboratory published alarge body of work involving bulk endocytosis– the engulfment of a large portion of theplasma membrane – in the maintenance ofneurotransmitter release.Despite decades of research, the molecularmechanism underpinning exocytosis remainspoorly understood. Emerging trends suggestthat the protein Munc18 acts as a chaperoneto promote the delivery of Syntaxin1 to theplasma membrane - an essential protein forexocytosis, via a trafficking pathway that is yetto be characterised.The Meunier laboratory and its collaboratorshave hypothesised that the Munc18 traffickingpathway is responsible for populating theplasma membrane with Syntaxin1. This isa highly significant trafficking pathway assecretory vesicles rely on Syntaxin1 to undergoregulated fusion. Researchers believe thefailure of this pathway at any stage completelyblocks neuroexocytosis in neurons, neurosecretorycells and insulin-releasing cells.They have also uncovered a novel form ofregulation helping secretory vesicles toacquire the competence to release theircontent by exocytosis. This provides the firstdemonstration of a link between calcium andPI3-kinase signalling pathways.This research provides the basis for a moredynamic view of the secretory mechanismof neurotransmitter release, with importantimplications for the treatment of conditionscharacterised by the diminished release of aneurotransmitter/hormone.PG | 41

We alsoactively participate in the internationalPsychiatric Genetics Consortium (PGC), whichis conducting genome-wide association studies(GWAS) on the largest available populationsof European ethnicity. Additionally, we areinvolved in the continuing recruitment andanalysis of the Australian SchizophreniaResearch Bank (ASRB) cohort. In all studies, wefocus on identifying homogeneous sub-typesand dimensions for use in genetic analyses.Our lab group has grown over the year, gainingfurther expertise in statistical genetics (Dr JakeGratten) and psychiatry and immunology (DrBill Mantzioris). During 2010 QBI establishedthe Centre for Brain Genomics (CBG), thecore of which is a second-generation DNAsequencer (Illumina HiSeq 2000). This is thefirst installation of a HiSeq 2000 in an Australianresearch institute. Bryan Mowry is CBG Director,Ms Vikki Marshall is Centre Manager withexpertise in molecular genetics and Dr DenisBauer is the CBG bioinformatician consultantfor user groups. The HiSeq 2000 was installedtowards the end of 2010, paving the way for QBIto undertake its first sequencing projects.Work funded by National Health and MedicalResearch Council (NHMRC) grants has alsoprogressed this year, with the completion ofa GWAS in the Iban of Sarawak, the analysisof second-generation sequencing data in aschizophrenia candidate gene in the southernIndian population, and the ‘deep phenotyping’of a sub-set of schizophrenia patientswith documented copy number variations(structural genomic variants).

The specificity and affinityof these antibodies to their targets and theirrelevance in a biological context is the subjectof further studies, with a long-term goal ofproviding pure populations of well-characterizedcells for trialling compounds whichincrease or rescue stem cell numbers.The year also saw the publication ofstudies on the role that particle size hason the yield obtained from cell sortingexperiments. This work on the fundamentalsof cell sorter function has implications forfuture experimental design and alters theexpectations of results from sorting large orirregular sized particles such as those typicallyfound in neural samples. It is now the basis forongoing research into cell sorting yield andcell recovery that seeks to identify the factorsthat contribute to variability in experimentaloutcome.

The ability of ultra high-field MRI tocharacterise the blood flow and structure ofliving systems, together with developments inMRI biomarkers, will allow researchers to betterphenotype animal models of disease and tomap the cognitive function of the brain.PET measures the distribution and fate ofmolecular markers using radiolabelled ligands,providing UQ researchers with the capacityCreating images to explore living organismsto perform, for the first time, in vivo studiesof metabolism, receptor-ligand binding andgene expression. The ability to study theliving organism enables longitudinal studiesof normal development, of the natural historyof disease and of responses to novel therapies.Consequently, in vivo imaging methodshave also become platform technologies fordrug discovery and validation. By providingsurrogate end points to assess the effectivenessof new therapies in clinical trials, a coherentimaging framework also speeds translation ofscientific discoveries to clinical realisation. MRIand PET are now core investigative modalitiesin virtually all clinical specialties, informingclinical diagnosis and prognosis and facilitatingthe goal of personalised medicine by bettercharacterising both disease and its response totreatment in the individual patient.Using these imaging tools, research in ourlaboratory in 2010 has involved creating newatlases of the mouse brain, developing newbiomarkers of epileptogenesis and strokeprogression and developing new methodsof mapping neural currents and using MRIinformation to map functional activity in thebrain.PG | 45
Professor Laboratory Perry Head Bartlett Professor Laboratory Linda RichardsResearchers in Professor Linda Richards’ laboratory investigate how thebrain forms connections during foetal development. The laboratory isfocussed on understanding the mechanisms regulating the formation ofthe cerebral cortex and the corpus callosum, which connects the left andright sides of the brain and is involved in higher-order cognitive processes.These processes include sensory and motor information processing as wellas speech, emotions, memory formation and storage, and many otherbrain functions.Above: Richards group photo. 2010 Laboratory Members: John Baisden, Erica Little, Oressia Zalucki, Amber-Lee Donahoo, Sharon Mason, Ilan Gobius,Samantha Liu, Skyle Murphy, Guy Barry, Michael Piper, Randal Moldrich. Above Right: A sagittal slice through the cerebellum of a mouse brain.PG | 46Elucidating formation of foetal brain connectionsResearchers in the Richards laboratory havemade several important discoveries during2010. For several years, laboratory membershave been studying the role of a family of transcriptionfactors known as the nuclear factorone gene (Nfi) family in the development ofthe cerebral cortex. Until recently little wasknown about how Nfi genes regulated theseevents at a molecular or genetic level. Recentresearch has shown that Nfia plays a pivotalrole in regulating proliferation and differentiationof hippocampal neurons. It does thisby simultaneously turning off genes requiredfor proliferation, such as Hes1 and turningon genes required for differentiation, suchas mature glial markers. This represents aconceptual advance in understanding that, forcells to proceed to differentiation, they mustfirst cease proliferation.The group also published its landmark studyon the discovery of the mouse commissuralplate. Since the early 1900s, it has beenhypothesised that a specialised region ofthe brain might exist that is important forthe formation of all forebrain commissures,axonal tracts that connect the two sides of thebrain. The group identified that a commissuralplate exists in mice and is made up of fourdistinct regions, each with molecular andgenetically defined boundaries. This workwill help to identify whether disruption of thecommissural plate in humans might underlieagenesis of the corpus callosum, which occursat a rate of 1 in every 4,000 live births.During the year, the group also published workcomparing various tractography methods foroptimising our ability to study axon tracts inthe developing brain.Neurons labelled by in uteroelectroporation of a fluorescentprotein in the cortex send axonalprojections across thecorpus callosum.
Queensland Brain Institute Annual Report 2010Laboratory Professor Head Thomas Professor Burne Pankaj Laboratory SahThe focus of the Sah laboratory is to understand how sensory informationreaches the amygdala, is processed, stored and retrieved. The amygdala is,in evolutionary terms, an ancient part of the brain that stores and retrievesemotional content to our sensory world. Dysfunction of the amygdalaleads to a range of disorders including anxiety, phobias and post-traumaticstress disorder. It is the long-term goal of the Sah laboratory to discovermolecular targets within the amygdala for the development of morespecific treatments for anxiety-related disorders.Above right: Sah group photo. 2010 Laboratory Members: Eleanora Autori, Sue Campbell, James Crane, Peter Curby, Andrew Delaney, Christine Dixon,Kathryn French, Helen Gooch, Robin Johnson, Sepideh Keshavarzi, Roger Marek, John Morris, John Power, Petra Sedlak,Jay Spampanato, Cornelia Strobel, Robert Sullivan, Tim Tatterstall, Francois Windels.Shown is a neurone in the medialamygdala in an acute brain slice.The image is a compressed stackimaged a Zeiss 710 two photonmicroscope.

Now researchersin the group have developed recordingtechniques using tetrodes implanted in awakebehaving animals in which the activity in theamygdala and other connected brain regionsis recorded as they undergo behavioural tasksthat engage the amygdala These recordingsallow researchers to follow the cellularactivity of different regions in the brain, inExploring learning and memory formationparticular the amygdala, as the animals learnand remember.Using two-photon imaging, researchers in theSah group have also examined how synapticinputs impinging on pyramidal neurons inthe basolateral amygdala initiate calciumsignalling mechanisms. This has led to thefinding that synaptic activity initiates calciumwaves in dendrites that propagate to thenucleus. These calcium waves also invadesome dendritic spines but do not enter others.Changes in calcium are likely to underlie howlearning takes place in the amygdala.NMDA receptors are activated by glutamateand initiate the molecular events that underlielearning and memory formation. Thesereceptors are made up of combinationsof different subunits that are thought toplay different roles during the learningprocess. Using a combination of molecularmanipulation and physiology in acute brainslices, the Sah group has also examined thedistribution of different subunits that make upNMDA receptors at different synapses in theamygdala.PG | 47
Laboratory Head Professor Mandyam SrinivasanFlying insects display remarkable visual agility, despite their relatively smallbrains and simple nervous systems. Professor Mandyam Srinivasan’s groupuses honeybees and budgerigars as models to understand how visualinformation is used to guide flight and facilitate navigation. Another aimis to explore whether some of these insights can be used to devise novel,biologically inspired strategies for the guidance of autonomous aerialvehicles.Above: Srinivasan group photo. 2010 Laboratory Members: Samuel Baker, Parthasarathy Bhagavatula, Daniel Bland, Natalie Bland, Brenda Campbell,Nikolai Liebsch, Tien Luu, Eliza Middleton, Richard Moore, Navid Nourani, Dean Soccol, Saul Thurrowgood, Gavin Taylor, William Warhurst. Above right:A tethered bee flying in a virtual-reality apparatus for investigating the visual mechanisms of flight control.PG | 48Translating flight findings into aeronautical applicationsAlthough research has revealed how insectsuse vision to guide their flight, little is knownabout whether flying insects actively avoidmid-air collisions and, if so, how they achievethis. The Srinivasan group’s recent study ofbees flying through narrow passages showsthat collisions occur at a much lower rate thanpredicted by chance, suggesting that beesactively avoid them. Three-dimensional reconstructionof the trajectories shows us howcollisions are avoided.Orchestrating a smooth landing is a challengingtask for any animal or machine, particularlyin the presence of wind. After establishingthat bees tend to land facing into the wind,we discovered in 2010 that bees do this evenwhen the substrate is devoid of visual texture,suggesting the direction of landing is guidedby cues additional to optic flow. We also foundthat bees are able to orient their landings atwind speeds as low as 0.8 m/sec, indicating ahigh sensitivity to this external disturbance anda remarkable ability to compensate for it.We filmed and analysed the flights ofbudgerigars to uncover strategies birds useto fly safely through dense and clutteredenvironments. Some findings parallel thosepreviously observed for flying insects,suggesting that certain principles of visualguidance may be shared by all diurnal, flyinganimals.In the area of biologically inspired robotics, wehave designed, developed and successfullytested vision systems that implementautomatic and efficient changes of aircraftaltitude and attitude, use horizon-basedinformation to perform a range of extremeaerobatic manoeuvres (such as loops) andenable a vehicle to detect the presence ofsalient landmarks in its environment fromthe patterns of image motion generated in acamera image.PhD student Samuel Baker with amulti-rotor aircraft that will embodybiologically inspired algorithms fornavigation.
Queensland Brain Institute Annual Report 2010Laboratory Head Assoc. Professor Bruno van SwinderenThe van Swinderen laboratory uses the fruit fly model Drosophilamelanogaster to investigate perception and cognition. Combining moleculargenetic tools with high-throughput behavioural testing and electrophysiology,the group studies the underpinnings of complex phenomena suchas selective attention, memory and sleep in the more simple fly brain. Thishas important parallels to the human brain, which must suppress partsof the outside world in order to pay attention, learn and sleep. How thissuppression mechanism works is a key question of the laboratory.Above right: van Swinderen group photo. 2010 Laboratory Members: Angelique Paulk, Bart van Alphen, Ben Kottler, Oressia Zalucki, Thomas Pollak, BenCalcagno, Melvyn Yap, Oliver Evans, Joanne Daniels, Rebecca Morley. Above left: Dr Bart van Alphen and Dr Angelique Paulk in the laboratory.A tethered fruit fly prepared for brainrecordingsThe van Swinderen laboratory has uncoveredDrosophila memory mutants that also haveattention defects. These mutants, which forthe most part are involved in protein synthesisdependentmemory consolidation pathways,were found to be less distractible thanwild-type flies. Genetic rescue experimentssuggest that neural wiring during early braindevelopment is crucial for eventual attentionlikeprocesses in adult flies. These defectsare being examined as potential models forautism spectrum disorders in humans.Recently, a behavioural screen has uncoveredanother memory mutant, called radish, whichCreating fruit fly models of autism and ADHDdisplays behaviours characteristic of attentiondeficit and hyperactivity disorder (ADHD)in humans. These ADHD-like symptomswere determined using behavioural testsas well as electrophysiology. Interestingly,radish attention deficits uncovered by theseparadigms were rescued by exposing flies tothe same drug used to treat ADHD in humans,Ritalin (methylphenidate). This suggests thatsimilar molecular pathways control attentionlikebehaviour in flies and humans, and thatthese pathways operate in the same neuronsalready known to be required for memoryformation. These results point the way tounravelling how memory and attentioninteract in a model brain.To better address neural mechanisms ofattention in the insect brain, the van Swinderenlab has recently set up a multi-channel brainrecordingparadigm for flies and honeybees.Neural dynamics (both spiking activity andlocal field potential) are analysed in responseto competing visual stimuli. The greater accessibilityof the bee brain combined with genetictools in Drosophila recordings provides asynergistic approach to understanding attention-likeprocesses in insect brains.PG | 49
Laboratory Head Professor David VaneyProfessor David Vaney retired as a Professorial Research Fellow at theend of 2010, after a 35-year career studying the structure and function ofthe retina. He will continue to maintain an academic association with theQueensland Brain Institute, having being appointed Emeritus Professorfollowing his retirement. Professor Vaney will be based in ProfessorMarshall’s laboratory, occupying the same space where he worked for20 years as a foundation member of the Vision, Touch & HearingResearch Centre.Above: Vaney group photo. 2010 Laboratory Member: Ben Sivyer. Above right: Dye-filling of the newly discovered type of retinal ganglion cell shows thatits processes dive in and out of three layers of the inner retina, each represented by a different colour. Image Ben Sivyer.PG | 50Shining light on visual processing in the retinaAll photoreceptors in the retina respond tolight by decreasing neurotransmitter releasewith increasing brightness of light. By contrast,the retinal neurons that lie downstream maybe either excited or inhibited by light. Theretinal ganglion cells (RGCs), whose axonsconvey visual information from the eye tothe brain, fire nerve impulses when light isturned either On or Off. In addition, it has longbeen known that two types of RGCs fire atboth light On and Off, namely the directionselectiveganglion cells (DSGCs) and the localedge-detectors(LEDs).Ben Sivyer, a PhD student in the Vaneylaboratory, discovered that there is a third typeof On–Off RGC, which responds transiently toillumination, like the DSGCs but unlike theLEDs. However, this novel type of RGC showsno directional preference for moving visualstimuli, like the LEDS but unlike the DSGCs.Even though these ‘transient On-Off RGCs’receive similar excitatory inputs to the DSGCs,the two types branch at different levels in theinner retina, indicating that they receive theirinputs from different types of retinal bipolarcells.The transient On-Off RGCs are conservedacross diverse mammalian species, andthus represent an ancient channel for thetransmission of visual information. Howeverit is not clear why 3 types of On-Off RGCsare required for visual processing or, forthat matter, why there are 15-20 types of allRGCs. There must be much redundancy inthe information conveyed to the brain by thediverse populations of RGCs. Understandinghow the visual scene is represented by theirtotal activity is one of the major outstandingproblems in retinal neuroscience.This dye-filled rod amacrine cell iscolour-coded to show the differentbranching levels in the inner retina.Image David Vaney.
Queensland Brain Institute Annual Report 2010Laboratory Head Dr Robyn WallaceThe Wallace laboratory explores the genetics of neurological disorders suchas motor neuron disease (MND) and epilepsy. MND is a rare, incurabledisorder with late onset. Although only a small percentage of MND casesare due to genetic mutations, Wallace group researchers are exploringhow these genes cause MND and working towards potential treatments.Epilepsy is a common, complex disorder with a strong genetic component.Having successfully identified several human epilepsy genes, the groupcontinues to characterise the functional consequences of the mutations.Above right: Wallace group photo. 2010 Laboratory Members: Marie Mangelsdorf, Tim Butler, Ramesh Narayanan, Ajay Panwar.

TDP-43is a protein involved in gene regulation but itsfunction in the nervous system is currentlyunknown and its role in the pathogenesisof MND remains unclear. We have identifiedgene targets of TDP-43 and are investigatingthe functional consequences of TDP-43mutations in MND patient stem cells.Potential outcomes of this project includeIdentifying functional consequences of gene mutationscrucial insights to understanding how motorneurons degenerate in MND and the identificationof novel therapeutic targets.The Wallace lab has also been analysing agenetic mouse model of MND, which carries amutation in another MND gene known as SOD1.In collaboration with the Centre for AdvancedImaging (CAI), we have demonstrated thatmagnetic resonance imaging is able to detectspinal cord degeneration in live mice. Thehigh resolution imaging technique developedis an important breakthrough, as mice nolonger need to be sacrificed to examine spinalcord pathology. This research has importantimplications for future drug trials as it has thepotential to reduce the number of animalsrequired.In addition to MND research, researchers arecontinuing to study the genetics of epilepsy.We recently discovered a new gene mutationthat causes a specific form of epilepsy knownas myoclonic astatic epilepsy. We are nowinvestigating exactly how this novel epilepsygene alters nerve cells in the brain to makethem susceptible to seizure activity.PG | 51
Laboratory Head Assoc. Professor Stephen WilliamsAssoc. Professor Stephen Williams joined QBI in 2010 to establish a SynapticPlasticity laboratory which investigates key questions of single neuron andneural network computation. Synapses connect networks of neurons andfacilitate information transfer between cells. A single neuron in the centralnervous system may receive thousands of synaptic inputs distributed widelyacross its dendritic arbor. Neurons must integrate such time-varying inputsignals to form an output signal, or action potential, which is communicatedto other neurons and/or effector systems like muscles.Above: Williams group photo. 2010 Laboratory Members: Arne Brombas, Ben Sivyer. Above right: Synaptically connected layer 1 inhibitory interneuronand layer 2/3 pyramidal neuron.Form and function of neural pathways in the neocortexResearchers in Assoc. Professor StephenWilliams’ laboratory are investigating keyquestions of single neuron and neural networkcomputation. They use advanced electrophysiologicaltechniques that allow simultaneousrecording from multiple dendritic sites of asingle neuron and computational modelling toexplore the synaptic integration mechanism inneurons of diverse morphology. The group’saims are focused on understanding the computationaloperations of the most numerousneuronal classes in the brain region calledthe neocortex (pyramidal neurons) and theirrelation to the physiological function ofneuronal networks.To explore this, members of the Williamslaboratory activate determined neuronalpathways in the neocortex using light-activatedion channels and measure how such inputsignals are integrated in the dendritic treeusing multi-site electrophysiological recordingtechniques. In September 2010, groupmembers participated in a Brain PlasticitySymposium at QBI, where Assoc. ProfessorWilliams spoke on the subject of synapticintegration in the first layer of the neocortex.The Williams laboratory is also involved in anactive collaboration with research groups at theHoward Hughes Medical Institute, Janelia FarmResearch Campus, in the USA. Through the useof multi-site two-photon glutamate uncagingtechniques, researchers are exploring thedeterminants of dendritic synaptic integration.This research will enable neuroscientists tobetter understand how networks of neuronsfunction in the neocortex and how theseprocesses are disturbed in disease.PG | 52Inhibitory neuronal classes inlayer 1 of the neocortex.

StudentsStudents play a vital role in research effortsat QBI. Research higher degree students, inparticular, are the linchpins of our laboratories– accordingly, the Institute aims to maintain acohort of around 80 PhD and MPhil degreestudents each year.In 2010, QBI had 72 students enrolled at theInstitute, of which 28 were from a diversity ofcountries, including Canada, China, Germany,Iran, Malaysia, Taiwan and Bangladesh. Nineteenstudents commenced their candidature, andthree PhDs were conferred – Stacey Cole (CooperLab), Ben Sivyer (Vaney Lab) and Divya Unni(Richards Lab). Dr Unni is QBI’s first internationalstudent to graduate with a PhD. These graduateshave subsequently gone on to postdoctoral workor into research administration.The high calibre of students attracted to QBIis attested to by their success securing highquality, competitive scholarships. In 2010,two of our incoming international studentsreceived the top international scholarshipsavailable at UQ, comprising the InternationalPostgraduate Research Scholarship (IPRS) alongwith the UQ Centennial Living Allowance andthe UQ Advantage Top Up. These students wereShao-Chang Huang (Reinhard Lab) and ElizabethKita (due to commence in the Goodhill Lab in2011). Three of the twelve prestigious NHMRCPhD Scholarships awarded to UQ students in2010 went to QBI: Ben Kamien (Richards Lab),John Morris (Sah and Mattingley Labs) and HughSimpson (Goodhill Lab).Undergraduate students are also welcomed intothe Institute as part of the Summer Scholarsprogram and many pursue further studies withQBI as a result of this experience. For example,Aanchal Sharma, from New Zealand, is a formerSummer Scholar who is currently undertakinga PhD in the Coulson Lab. It is pleasing to notethe increasing popularity of this program, withQBI welcoming its largest number of SummerResearch Scholars since the program began in2008, with a total of 23 students in our labs overthe Christmas and New Year summer break.Student success storiesThe continuing progress of QBI students, bothpast and present, has confirmed that Institutegraduates are ones to watch.Dr Benjamin SivyerOne of those who continues to stand out fromthe crowd is PhD candidate Ben Sivyer, who in2010 was awarded a Dean’s Commendation forOutstanding Research Higher Degree (RHD) thesison the physiology and anatomy of a class of rarelyencountered ganglion cells in the mammalianretina. The UQ Graduate School instituted theDean’s Commendation for Outstanding RHDThesis in 1998, to give formal recognition tooutstanding PhD and MPhil graduates whoreceive unanimous commendations from theirexaminers for a substantial contribution to theirfield of research. No more than 10 per cent ofRHD graduates are recognised in this way and DrSivyer was the only QBI graduate to receive thisaward in 2010. This commendation follows onfrom a string of previous successes, including theMichael F Hickey Memorial Honours Prize (2006)for obtaining the highest overall percentage inthe Anatomy Honours Program and the IstvanTörk Prize (2009) for the best oral presentation bya Student Member of the Australian NeuroscienceSociety (ANS).Dr Adrian CarterDr Adrian Carter was one of the first studentsto complete his PhD through the QueenslandBrain Institute, graduating from The Universityof Queensland at the end of 2009, and was alsothe recipient of the Dean’s Commendation forOutstanding RHD Thesis in 2009. Dr Carter hassince continued a close association with QBIwith Professor Wayne Hall via his appointmentat the UQ Centre for Clinical Research. ThereAdrian continues to investigate the social andethical challenges of neuroscience research andemerging neurotechnologies for the treatment ofaddiction. This research includes an examinationof the impact that neuroscience has on understandingof addiction, including notions ofautonomy and responsibility, the use of coercionand the capacity to consent to addiction research,and the use of emerging technologies, such asdeep brain stimulation and drug vaccines, to treataddiction.PG | 56Above: Dr Hugh Simpson received anNHMRC PhD Scholarship in 2010.

Queensland Brain Institute Annual Report 2010CommunityQueensland Brain Institute researchers form anintegral part of the communities in which they workand live. They regularly discuss the latest researchdiscoveries with community groups, while alsoengaging with their peers at scientific conferences.In 2010, QBI hosted a series of high profile lecturesand conducted a range of community outreachevents. In addition to educating Australiansabout the latest research findings, staff alsoexpanded their efforts to encourage the nextgeneration to consider careers in neuroscience.A group from the Mental Illness Fellowship ofQueensland visits QBIPG | 59
QBI EventsPeter Goodenough Memorial LectureToshiya Yamada Memorial LectureDollars and SenseResearch Gene-iusQBI welcomed a leading philanthropiccampaigner to present the Peter GoodenoughMemorial Lecture in early April.Dr Sarah Caddick is the principal neuroscienceadvisor for the UK’s Lord David Sainsbury’s GatsbyFoundation. She has built her career advocatingthe importance of donating to science – and saidthere has never been a better time for the publicto become involved.“We’re going to figure out how the entire brain iswired up at some point. This is the future – whodoesn’t want to know why we think, how we thinkand where our memories come from?” she asked.The former neuroscientist explained thatinstitutes conducting fundamental studies – suchas QBI – are leading research efforts.“Basic science is where the answers are. There isno example of a discovery, therapy or a diagnosticthat has come from the translational end.”Dr Caddick predicted research funding wouldevolve in the future, with increased collaborationsbetween research laboratories and a greateremphasis on philanthropy.“It is extremely challenging for any system ofpublic grant making to take major risks. It’s alsochallenging for them to explore new areas,” shesaid.“Philanthropists are usually less burdened withbureaucratic controls and can take those risks.”During the lecture, she acknowledged thegenerosity of the late Peter Goodenough, whosesignificant bequest led to the establishment of amotor neuron disease laboratory at QBI.“The idea of funding basic research is exactlywhat we established this Institute for, so this idearesonates extremely well with us,” QBI DirectorProfessor Perry Bartlett said about the “veryrefreshing” lecture.There was a packed house for the ToshiyaYamada Memorial Lecture in June, hosted jointlyby UQ’s Queensland Brain Institute and theInstitute for Molecular Biosciences (IMB).Dr Yamada was an outstanding mid-careerscientist at UQ’s Centre for Molecular and CellularBiology (now the IMB) who died suddenly in 2001.Guest speaker for the annual lecture wasProfessor John Hardy from the Reta Lila WestonInstitute of Neurological Studies at UniversityCollege London.After starting his career researching Alzheimer’sdisease, Professor Hardy went on to lead thegroup that found the first mutation in theamyloid gene, which causes the condition. Hewas also part of the teams that discovered thegenetic mutations that lead to Parkinson’s andPick’s diseases.The geneticist used the lecture to give scientistsan update on the sequencing of both Alzheimer’sand Parkinson’s diseases.“As the number of people who are sequencedincreases, more and more variants are enteringthe databases. This is very powerful as we canpredict who has very rare mutations withoutsequencing them,” he said.A Fellow of the Royal Society, UK, ProfessorHardy also took the opportunity to inspire youngresearchers considering a career in genetics.“This is an amazing time to be a genomics-basedresearcher. It’s the beginning of a golden era.”IMB Director Professor Brandon Wainwright said:“Professor Hardy has demonstrated the power ofgenetics to impact all of our studies.”He went on to describe the lecture as a fittingtribute for “our much missed colleague, Toshi”.PG | 60Above: Dr Sarah Caddick.Above: Professor John Hardy(centre, white shirt).
QBI ConferencesEpigenomics, Behaviour and DiseaseSymposiumChanging BehaviourSummer of Spikes Lecture SeriesSpike up your LifeMotor Neuron Disease (MND)SymposiumMiND MattersIntroducing Addiction NeuroethicsConferenceThe Neuroethics of NeuroscienceResponding to increasing interest in thestudy of inherited changes in appearance andgene expression, QBI hosted the inauguralEpigenomics, Behaviour and DiseaseSymposium in March.“Many questions of adult behaviour in thenervous system have some component ofepigenetics – there couldn’t be a more excitingtopic,” said QBI Director Professor Perry Bartlett.Among the speakers was University of Zurich’sProfessor Isabelle Mansuy, who revealed thatchronic maternal deprivation leads to impulsiveand depressive behaviour in future generations.“The maternal environment is of greatimportance for the normal development ofchildren,” she said.“Some traits disappear in the fourth generation,but some stay … We’re testing the theory thatthese traits can be reversed by drugs or environmentalfactors.”The symposium organiser, QBI’s Dr TimothyBredy, said work presented at the conferencerepresented major advances in the understandingof gene-environment interactions in thecontext of human disease.“It’s clear that the epigenome is playing a centralrole in that,” he said.Better understanding the link betweenlearning, rhythm and computationalneuroscience was at the core of the Summerof Spikes lecture series organised by theThinking Systems Group and held at QBI overthe 2009-2010 festive season.By increasing the understanding of these keyareas, scientists hope to advance research intoneurological disorders.QBI’s Dr Angelique Paulk, who organised theseries with Dr Peter Stratton and ProfessorJanet Wiles said: “Direct interaction betweenscientists provides the ground-work for trulynovel research which would not otherwise occur.That’s why we decided to organise this courseand unite eminent researchers from the computationaland empirical neuroscience disciplines.”Guest speakers included Assoc. ProfessorJean-Mark Fellous, University of Arizona, USA,who researches the role of noise in neuralcomputations; and Professor Anthony Burkitt,University of Melbourne, and Assoc. ProfessorMichael Breakspear, University of New SouthWales, who use mathematical concepts to betterunderstand neurological functions.Neuroscientists from across the globegathered at QBI to learn more about the latestdevelopments in motor neuron disease (MND)research in February.The symposium gave researchers theopportunity to discuss advances across a rangeof areas, including the molecular and cellularmechanisms, genetics and diagnostic markersof MND, as well as treatment strategies andimaging.“This highly successful symposium broughtthe clinical, scientific and public communitiestogether for the exchange of ideas and newscientific knowledge on current issues in MND,”conference organiser Dr Robyn Wallace said.The Australian Neuroscience Society satellitemeeting also included a series of oral andposter presentations, illustrating the qualityand breadth of research that is currently beingconducted into MND across the country.Neuroscientists are committed to improvingdrug treatments for a range of illnesses – butit is important to consider the ethical, socialand policy implications of the treatments theydevelop.Addiction is a serious illness for many people,however research is only now starting to revealhow drugs act on the brain to cause dependenceand why some people are more prone todeveloping addiction than others. This researchcould lead to more effective treatments foraddiction and transform social policy.Many questions remain unanswered, includingwhether people are responsible for drug-inducedbehaviour that harms others and whetherpsychotropic drugs that enhance brain functionssuch as memory, concentration and moodshould be allowed.International speakers Professor Judy Illes fromthe University of British Columbia, Canada, andAssoc. Professor Eric Racine from Université deMontréal and McGill University, Canada, joinedthe conversation at the Introducing AddictionNeuroethics Conference in April.Conference organiser, QBI’s Professor WayneHall, said: “It is important that we consider theimpact of neuroscience research if we are tomaximise the benefits it offers.”PG | 62
Queensland Brain Institute Annual Report 2010QBI ConferencesBrain Plasticity SymposiumThe Flies Have ItComputational NeuroscienceWorkshopMaths and MysteryCharles Watson Short CourseForebrain basicsVision Down Under 2010Festschrift for David VaneyMark Twain rarely comes to mind when youthink of neuroscience.However he was central to a lecture by ProfessorRon Davis who tried to debunk the quote “thegood Lord didn’t create anything without apurpose – but the fly comes close” at the BrainPlasticity Symposium in September.Professor Davis, from the Baylor College ofMedicine, USA, spoke about the importanceof the fruit fly Drosophila in understandingmemory in humans.“In the past few years we have identified severalmemory traces. It appears that olfactorylearning is actually multiple memory phases inthe olfactory nervous system,” he explained.A plethora of national and international speakersspoke on a range of topics, covering neuralcircuit construction and function in sensorysystems, memory and psychopathology, acrossthe two-day symposium.QBI’s Deputy Director (Research) and symposiumco-organiser Professor Pankaj Sah said: “Thissymposium showcased new developments inthis exciting area of neuroscience. The postersession was particularly good and provided anopportunity for QBI students and staff to spendtime with leaders in the field.”Research leaders from Australia and overseasgathered at QBI in November for the AustralianWorkshop in Computational Neuroscience.First held at QBI in 2006, the two-day workshopgives computational neuroscientists theopportunity to learn more about the latestdevelopments in their field, while also discussingpotential collaborations with other researchers.Computational neuroscience is the study of theinformation-processing properties of nervoussystems, using a combination of mathematicaland experimental techniques.“A computational approach is essential for fullyunlocking the mysteries of brain function,” saidworkshop organiser and the head of QBI’s computationalneuroscience laboratory ProfessorGeoffrey Goodhill.Guest speakers also included Professor PeterDayan from University College London andDr Si Wu from the Institute of Neuroscience inShanghai.More than 50 people attended a short coursehosted at QBI in August by Professor CharlesWatson, Professor of Health Sciences at CurtinUniversity in Western Australia.Entitled ‘The forebrain tracts – histology andMR images’, the workshop focused on the fibresystems of the forebrain, first with histologicalsections, and then with MR scans of mousebrains.Formal lectures preceded related group projectsessions.Participants were provided with a review of theorganisation of the forebrain, an outline of themajor fibre systems of the forebrain as seen infibre-stained histological sections and interpretationof MR images of the mouse forebrain,including the thalamus, hypothalamus,subpallium and cerebral cortical areas.This was the third in what has become an annualshort course in neuro-anatomy.Professor Watson is a world-leading authority onfunctional anatomy of the nervous system. Hiscourses are always extremely popular and wellreceivedby those who attend them.On 1 December, QBI hosted the third ‘VisionDown Under’ meeting.The event marked the retirement of ProfessorDavid Vaney and provided an opportunity tocelebrate his many outstanding contributions tovisual neuroscience and to wish him well in thenext step of his life.VDU 2010 featured talks by Professor Vaney’spast and present collaborators and colleagues,on topics ranging from axon guidance inarthropods to the Bradshaw rock paintings ofthe Kimberley.Professor Vaney will retain close ties with theInstitute as he has been appointed EmeritusProfessor of The University of Queensland.Above: Professor David Vaney (centre, black shirt) with delegates from VDU 2010.PG | 63
Government RelationsFederal visitIn July, QBI was privileged to showcase itsresearch to Mr Mark Butler in his capacity asParliamentary Secretary for Health and MrSteven Miles, the Labor candidate for Ryan.The visitors met with Professor Perry Bartlett whoprovided them with an overview of QBI's unique“fundamental research” focus before walking themthrough a few laboratories. The final stop was atthe research benches of Drs Daniel Blackmore andDhanisha Jhaveri where the spotlight was on therecent developments in dementia research.Against a backdrop of Australia’s greyingpopulation, ageing dementia is emerging as oneof the country’s most pressing health problems.It is expected to present significant challengesto our health care system, which makes directedresearch programs aimed at preventing andtreating ageing dementia and preserving qualityof life for older Australians all the more urgent.State focusQueensland Education and Training InternationalThe Queensland Brain Institute took out the “BestPractice in International Collaborations” in theResearch category during the 2010 QETI Awardsfor Excellence ceremony in November.This award was in recognition of QBI's successfulcollaboration with the Institute of Biophysics inBeijing (further details on opposite page).The QETI awards occur on an annual basisand showcase Queensland’s international andtraining institutions’ best practice in internationalcollaboration and student services.The award was presented to Professor PerryBartlett by Mr Michael Choi MP, ParliamentarySecretary for Natural Resources, Mines andEnergy, and Trade and Investment Queensland.Professor Bartlett used the opportunity tobrief an interested Mr Butler on QBI's plans fora much-needed Centre for Ageing DementiaResearch.

Queensland Brain Institute Annual Report 2010International PartnershipsNeuroscientists predict significant progressover the next decade or two when it comes toidentifying the causes and cures for disorderssuch as ageing dementia, depression and schizophrenia.Fortunately, the Queensland BrainInstitute is positioned at the forefront of suchdiscovery thanks to strategic partnershipsestablished across the globe.Joint Laboratory OpeningA growing research bond between theneuroscience communities of China andQueensland culminated in the opening at QBIin September of the world-first Joint Laboratoryof Neuroscience and Cognition with theChinese Academy of Sciences (CAS) Institute ofBiophysics (IBP) in Beijing. A second openingtook place in November at the IBP.The laboratory is underpinned by a $1 millionNational and International Research AlliancesProgram (NIRAP) grant from the QueenslandGovernment, which brings together researchersfrom QBI, Griffith University, IBP as well as theChinese Academy of Sciences’ Institute ofPsychology.The aim of the program is to identify the keymechanisms regulating brain plasticity and totranslate this understanding into promotingnormal functions such as learning, memory andcognition, as well as ameliorating diseases suchas dementia, depression, schizophrenia andneurotrauma.“Beijing’s expertise in fruit fly behaviour andresearch, along with high resolution, functionalmagnetic resonance imaging facilities, alignsclosely with our own,” says Professor PerryBartlett.“Over the next decade or two, this part ofthe world, and China in particular, will play aleading role in making discoveries in the area ofbiological science.”Research AlliancesA second exciting alliance with researchers inChina was formed in June 2010 with colleaguesat the Shanghai Changzheng Hospital at theSecond Military Medical University.The Memorandum of Understandingestablishing the alliance was signed by ProfessorPerry Bartlett, with Queensland TreasurerAndrew Fraser present, during Queensland Weekat the World Expo being held in China.It underpins the development of a Human NeurogeneticsResearch Program which aims toimprove therapeutic outcomes for neurologicaldiseases such as motor neuron disease (MND),schizophrenia and epilepsy.“This is a wonderfully unique opportunity forus to collaborate with outstanding clinicalresearchers at the Shanghai ChangzhengHospital, to uncover the genetic basis of a rangeof devastating brain diseases,” Professor Bartlettsays.Meanwhile, a nano-neuroscience collaborationwith colleagues at Fudan University isprogressing well.The collaboration aims to develop a moreefficient drug delivery system based on a novelclass of hybrid inorganic neuroparticles.A further bilateral agreement with Ludwig-Maximilians-Universität(LMU) in München, Germany,was established in October 2010.This has resulted in the planning of a jointsymposium to be held at QBI in 2011, which will beattended by researchers from the Munich Centrefor Neuroscience (MCN), a virtual centre in whichseveral faculties of LMU and other Munich-basedresearch centres participate to enable integrated,interdisciplinary neuroscience.The Memorandum of Understanding (MOU) withthe Institute of Neuroscience (ION) in Shanghai,also a Chinese Academy of Sciences Institute,was extended for a further five years. This hasproved to be a most successful collaboration,with regular exchange of staff and studentswhich enhance the research programs and haveculminated in a number of joint publications.Right Top: Bart van Alphen (white coat) talks with Professor Jinghai Li Vice-President Chinese Academy of Sciences in the laboratory during theopening of the QBI-IBP Laboratory of Neuroscience and Cognition at QBI.

Community OutreachQBI’s community outreach program isdesigned to engage people interestedin discovering more about neurologicaldisorders. The program’s success is proof ofthe public’s thirst to learn more about thelatest developments in this area of research.In addition to regular tours through QBI’sworld-class facilities, the Institute’s researchersfrequently conduct lectures, talks and discussionsthat are the anchor of the outreach program.This interaction – in libraries, bookstores, schools,hospitals and other community settings acrossthe country – has continually proven beneficialfor the public and scientists alike.As the community learns more about theresearch being conducted at QBI, the lecturesprovide an unparalleled opportunity forscientists to meet people who, in many cases,know someone affected by a neurologicalcondition. Engaging with people who willpotentially benefit from QBI’s research in thelonger term provides an additional impetus forthe neuroscientists to advance their work.In 2010, QBI’s researchers were involved inmore than 35 outreach events, including:The University of Queensland’s CentenaryOpen Day in April attracted more than 300people to the Institute to view our state-of-theartfacilities and learn more about our researchDr Michael Piper spoke to membersof Probus in Albany CreekProfessor John McGrath updated membersof the Mental Illness Fellowship of Queenslandon the latest in schizophrenia researchDr Judith Reinhard presented a talk to theLogan West Library on her research with beesAssoc.

Queensland Brain Institute Annual Report 2010Australia New Zealand Brain Bee Challengeout-smart, out-think, out-lastEstablished in 2006 to spark high schoolstudents’ interest in pursuing careers inneuroscience, the Australian Brain BeeChallenge (ABBC) went from strength tostrength in 2010. With neurological andmental illness accounting for almost half of thetotal disease burden in Australia, QBI views theABBC as one way of attracting the best youngminds to consider research careers.A record number of 4,526 Year 10 studentsfrom all around Australia and New Zealandparticipated in the 2010 competition, takingthe cumulative total number of participantssince the inception of the Challenge to 18,587.Designed to test students’ knowledge about arange of topics, including intelligence, memory,emotions, sleep, Alzheimer’s disease and stroke,the ABBC is the country’s largest neurosciencecompetition. It is affiliated with the InternationalBrain Bee (IBB), where the Australian and NewZealand Champions have the opportunity tocompete after their National win.held in Florence, Italy, during the InternationalBrain Research Organisation World Congress ofNeuroscience.Development of an ABBC Alumni program,designed to keep students connected to fellowalumni, organisers and, of course, the newestadvances in neuroscience, will be a focus for2011. Already, many former ABBC competitorshave taken up neuroscience careers within QBI.These include James Nightingale, CourtneyLanders, Katelin Haynes, Sophie Hill, CaseyLinton and Kristy Butler. Results such as thisdemonstrate that the ABBC is achieving itsgoals of stimulating and supporting students’fascination with science, and encouraging theircontinued interest throughout their highereducation and careers.The National Finals were held at the annualAustralian Neuroscience Society (ANS) meetingin Auckland. After a nail-biting two days ofcompetition, the 2010 Australian winner was BenThompson from Canberra Grammar School, nowstudying at Narrabundah College, with RachaelWiltshire from Samuel Marsden CollegiateSchool crowned as the New Zealand Champion.In July 2011, Ben and Rachael will compete atthe International Brain Bee Challenge beingLeft: 2010 ABBC winner Mr Ben Thompson.Above: Brain Bee competitors in the running.PG | 67

Fellowships and Awards2010 Nina Kondelos PrizeDeveloping ResearchProfessor Linda Richards was recognised forher research into how the brain developsbefore birth with the 2010 Nina KondelosPrize at the annual meeting of the AustralianNeuroscience Society (ANS) in January.The Nina Kondelos Prize is presented to a femaleneuroscientist for their outstanding contributionto basic or clinical research.“Linda has made a considerable mark in Australianneuroscience in the six years since she returnedto the country,” said QBI’s Professor David Vaney,President of the ANS at the time the prize waspresented.QBI PhD students Dana Bradford and Ben Sivyerwere also recognised at the ANS conference in2010, winning two of the five student posterprizes as part of the Sir Grafton Elliot-SmithAward.This was the second remarkable double achievedby the pair, who had both been awarded anIstvan Törk Prize for the best oral presentationby a Student Member of the ANS at the previousannual meeting in Canberra.In relation to the poster prize, Dr Bradford says,“It was great to see a friend win the same award –even if it did mean sharing the cash.”Schering-Plough SeniorResearch AwardRewarding ResearchTwo decades after he began researching thecauses of schizophrenia, Professor BryanMowry has been rewarded for his efforts.The psychiatric geneticist received the 2010Schering-Plough Senior Research Award for hiswork to identify the genes that make peoplesusceptible to developing schizophrenia and forinvestigating the illness’ genetic complexities.“It’s a great honour to receive this award,” saysProfessor Mowry.“It will hopefully engender, encourage andfacilitate a deeper interest in research, especiallyamong the younger generation of psychiatrists.”The judging panel from the Royal Australianand New Zealand College of Psychiatrists, whichpresented the award, said it was “thrilled” torecognise Professor Mowry as a joint winner withProfessor Ashley Bush from the Mental HealthResearch Institute of Victoria.QBI Director Professor Perry Bartlett congratulatedBryan on the accolade.“It's well-deserved recognition for his dedicatedwork in this field,” he says.Boycott PrizeEyes on the PrizeVisual neuroscientist Professor DavidVaney received the 2010 Boycott Prize forcareer achievement in the field of retinalneuroscience.The award, presented by Professor Vaney’scolleagues at the FASEB Summer ResearchConference on Retinal Neurobiology, recogniseshis research on visual processing in the retina.“The retina has been described as nature’sbrain slice because its structure and functionremain largely intact when studied in isolation,”Professor Vaney explains.“Many discoveries first made in the retina werelater shown to apply to other parts of the centralnervous system.”Professor Perry Bartlett said it was an honour forProfessor Vaney to be the first researcher fromAustralia to receive this prize, and its first solerecipient.The Boycott Prize was a fitting tribute forProfessor Vaney, who has played a leadingrole in neuroscience research, including atwo-year term as the President of the AustralianNeuroscience Society.PG | 70Above: Professor David Vaney, President of the Australian Neuroscience Society (ANS), presents the2010 Nina Kondelos Prize to Professor Linda Richards at the Annual Meeting of the ANS.Below: Professor Bryan Mowry is presented with the 2010 Schering-Plough award.
Queensland Brain Institute Annual Report 2010Fellowships and AwardsResearch FellowshipsFunding for FellowsUQ Research Excellence AwardsQBI ShinesQBI’s Dr Timothy Bredy has received acoveted Australian Research Fellowship whichcommenced in January 2010.His research will determine how the differencesbetween male and female brains contribute tothe formation and maintenance of long-termfear memories.Scientists have already identified that malesand females remember information in differentways – men primarily remember the gist, whilewomen focus on the details.Dr Bredy said improved understanding of thesex-specific differences could unlock the door tobetter treatments.“We’d certainly hope to be looking at newdirections in therapeutic approaches by the endof the grant,” he said.Meanwhile, QBI Faculty member and theDirector of UQ’s Centre for Advanced Imaging,Professor David Reutens, was awarded anNHMRC Practitioner Fellowship.The researcher, who uses functional magneticresonance imaging to learn more aboutneurological disorders, will use the five-year$500,000 grant to investigate nervous systemdisorders.The Queensland Brain Institute has again provenit is a rising star, with two of 11 University ofQueensland Research Excellence Awards beingpresented to QBI researchers in 2010.Dr Massimo Hilliard was recognised for his projectaimed at understanding nerve regeneration inthe roundworm Caenorhabditis elegans, whichcould eventually enable scientists to rebuildconnections in the nervous system after injury.“This prestigious recognition comes as a strongmotivation to our commitment to do goodscience and make important discoveries,” saysDr Hilliard.Dr Michael Piper was also rewarded for hisresearch studying the genes that regulate stemcell differentiation in the embryonic brain, whichis crucial for development.“It’s very humbling to get awards like these, asthey represent acknowledgement from yourpeers in the scientific community,” says Dr Piper.According to Professor Perry Bartlett, the raft ofawards secured in 2010 is further confirmationof the outstanding quality of the Institute’sresearch program.“QBI was extremely successful in snapping upthese awards – it’s a fantastic achievement,” headds.Right: Dr Massimo Hilliard in the laboratoryPG | 71
CommercialisationQBI’s commercialisation pipeline continuedto grow in 2010, with groundbreakingdiscoveries relating to the treatmentof glioma brain tumours and botulismpoisoning. However, the highlight of theyear came when an earlier discovery for thetreatment of neurodegenerative disease waslicensed to start-up company NuNerve PtyLtd.Neurodegenerative diseases are characterisedby the degeneration, and ultimately death,of neurons. In the seven years since QBI'sinception, researchers have identified factorswhich regulate both neuron survival (CoulsonLaboratory) and neurogenesis, the productionof new neurons (Bartlett Laboratory). Thebiotechnology company NuNerve Pty Ltdwas successful in raising $2 million and, in thefirst quarter of 2010, several patent familiesrelating to these breakthroughs were licensedto the company. The company’s focus is onthe development of novel technologies for thetreatment and prevention of progressive neurodegenerativediseases, particularly motorneuron disease (MND) and Alzheimer’s disease.In the second half of the year, QBI, partneredby NuNerve Pty Ltd, was successful in its bidfor ARC Linkage funding to further supportthe development of cell survival factors. WithNuNerve on board as a partner, we are lookingforward to further developing these promisingleads.Development of a treatment for acute spinalcord injury continues in collaboration withCSL Limited. QBI was successful in obtainingdevelopment funding from the National Healthand Medical Research Council (NHMRC) tosupport the development of this promisingprotein, EphA4, to treat acute spinal cord injury.Last year we completed proof-of-principlestudies in rats, demonstrating that treatmentwith EphA4 following spinal cord lesion notonly results in less scarring at the injury site andregeneration of the damaged cord, but also inrecovery of movement. We hope to progressthis treatment closer to the clinic in 2011.QBI’s commercialisation activities aresupported by UniQuest Pty Limited, the maincommercialisation company of The Universityof Queensland which provides access tocommercialisation expertise, processes andresources, and its Manager of Innovation andCommercial Development, Annita Nugent.PG | 72Image right: Neuronal production, in thenorepinephrine-stimulated adult hippocampalneurospheres, was visualized by Thy1-YFP (ingreen) and beta3-tubulin (in red).
