Prof. Greg Francis 1/2/12!! Poor spatialresolution!! You never reallySpatial resolutionknow which part ofthe brain is makingthe current!! Lots of work toimproveMagnetic Resonance Imaging!! Magnetic fieldforces protons inyour body to lineup!! pulses of radiointo fieldbouncesprotons around!! as they returnto normalposition, theyemit a signalthat can bedecoded into amapPurdue UniversityPurdue UniversityMagnetic Resonance Imaging!! MRI Scans: Like an x-ray machine, butcan look at soft tissue (like lungs, heart,..)!!Very good spatial resolutionMagnetic Resonance Imaging!! MRI Scans: Like an x-ray machine, but can look at softtissue (like ankles, my brain,..)!! Very good spatial resolution!! millimetersPurdue UniversityPurdue UniversityMRI ScansMRI Scans!! MRI providesa “slice” at atime!! Take multipleslices to buildup full image!! Can identifyanatomicaldifferences betweenbrains!! Alcoholic has largerventricles and thinnercorpus callosumNobel prizewinning work!Purdue University!! Note comparingacross brains is a bittricky!!! Everyone’s brain is abit differentPurdue UniversityPSY 200: Intro. to Cognitive Psychology 2
Prof. Greg Francis 1/2/12!! 3-D maps!! NormalMRI ScansMRI Scans!! Non-invasive, no side effects!! Allows early detection of brain disease,tumors,…!! Fantastic spatial resolution!! But…!! Ataxia:!!loss of motorcontrol!!it only shows structure!!no way to know what a brain area doesPurdue UniversityPurdue UniversityFunctional MRI!! Just like MRI, but with a new analysis!! MRI differentiates between different types of tissue (celltypes)!! Functional MRI differentiates between active andinactive neurons: concentration of oxygen!! The measurement is called the “blood oxygen leveldependent” (BOLD)»! It roughly tracks the flow of blood in the brain»! More active neurons recruit more bloodPurdue University!! Color maps showstrongest“responses”!! E.g., fMRI scan of awoman after a stroke!!Blue/green:normal blood flow!!Red/black:abnormal bloodflowFunctional MRIPurdue UniversityFunctional MRIScanning!! Consider this fMRI scan!! Very good spatialresolution!! millimeters!! Pretty goodtemporal resolution!! Seconds!! (Silva, 2002)!! It shows regional cerebralblood volume (rCBV)!! You cannot tell how/ifdifferent regions are involvedin different activities!! Breathing!! Digestion!! Thinking about exams!! …..Purdue UniversityPurdue UniversityPSY 200: Intro. to Cognitive Psychology 3
