modern technology and research
psychologists
instrusive techniques of investigation
neurologists
treatment of selected subjects and conditions
brain mapping techniques
wider population
observation of location and intensity of activity in living brain
capturing brain in action
brain mapping
attempt to provides A complete picture about how the brain works
relate the brain's structures to its function
find what parts of the brain give us certain abilities
goal= to achieve a 3D map of the brain, representing the surfaces, the structures within, and the functions of performed by components of structure
structures = where the components of the brain are located
functions= how the components act and interact to recieves and integrate information and to produce behavior
structural mapping
electrophysiological methods
by stimulating specific part of the brain and recording the corresponding response
enabling accurate mapping of location of different functions based on activity of individual neurons
neural hardware
connections linking one part of the brain to the other
principles underlying the ordering of these links
brain mapping techniques
structural
x-ray techniques
cerebal angiography
computed tomography
computer axial tomography (CAT)
magnetic resonance imaging (MRI)
functional
electrophysiological techniques
electroencephalography
event- related potential (EPRs)
blood-flow techniques
positron emmision tomography (PET)
single photon emission computed tomography (SPECT)
