Functional neuroimaging

Functional neuroimaging represents an area of brain imaging that has underg one tremendous advancements in the last decade. It is now possible to desig n experiments that elucidate the functional interplay between brain regions that give rise to specific human cognitive processes. Positron emission to mography (PET) and functional magnetic resonance imaging (fMRI) form the co re technologies that have allowed such studies. This article reviews the ba sis of these techniques, their strengths and limitations, the underlying ne urophysiology, and the future of functional neuroimaging.
