10:30 am – 12:35 pm SYMPOSIUM – WIRING THE OLFACTORY SYSTEMSChair/Organizer: Jean-Francois CloutierIsland BallroomThe detection of odorant signals from the environment relieson the formation of accurate stereotypical connections betweenolfactory sensory neurons (OSNs) located in the olfactoryepithelium (OE) and second order neurons located in theolfactory bulb (OB). In the mouse, most OSNs expressing asingle olfactory receptor project their axons to twosymmetrically bilateral glomeruli within the OB. How doOSN axons select their target glomeruli in the complexthree dimensional target field that represents an OB? The targetchoice of OSN axons appears to rely on a combination ofmolecular determinants that enhance the growth of axons tothe OB, promote their segregation into broad regions of theOB to form a crude topography and then favor their sortingand coalescence into specific glomeruli. This symposium willexamine recent progress in our understanding of the molecularmechanisms that underlie the formation of an accurateglomerular map.10:35 am #40 Mapping Odorant Receptor Classes in the MouseOlfactory BulbThomas Bozza, Rodrigo Pacifico, Jingji Zhang,and Brian Weiland, Department of Neurobiology andPhysiology, Northwestern University, Evanston, IL,United States11:05 am #41 Axon - matrix interactions regulate olfactory wiringHelen B.
