LOCALIZATION OF CORTICAL FUNCTION USING E LECTRICAL-STIMULATION AND FUNCTIONAL MAGNETIC-RESONANCE-IMAGING - PARADIGMS OF NEURONAL STIMULATION

In this review, localization of function is discussed with respect to distributed cortical areas involved in complex mental processing. Afte r introducing the methodology of lesion studies, some results of studi es using electrical cortical stimulation are presented. With respect t o functional magnetic resonance imaging, results and problems from sev eral experiments are reported, and further questions and perspectives regarding the two methods are outlined.
