Male, 32 years old, with epilepsy. Functional localization of language, motor and visual cortex for presurgical evaluation. Sensorimotor cortical activation of the hand, foot and face maps as expected along the pre- and post-central gyri. Passive visual stimulation elicits activation along the bilateral calcarine sulci.Of the tested language paradigms, the cleanest and most reliable language related cortical activation is seen with the verb generation paradigm. Language is left dominant. Broca's area is identified in its customary location of the left inferior frontal gyrus. Wernick's area is identified in its customary location along the posterior aspect of the left superior temporal sulcus.
Technically successful functional MRI for presurgical mapping. The sensorimotor and visual cortices are well delineated. Language is left dominant with Broca's and Wernicke's areas identified in their customary locations.
