and functional Magnetic Resonance Imaging (fMRI), they identified the cortical
and subcortical areas involved. They were then able to show that forming the

tomography) allow research correlating localized brain activity
with the performance of specialized cognitive tasks.
These varied techniques have allowed for the localization of
