Male, 33 years old, with seizures after encephalitis for presurgical evaluation. Sensorimotor cortical activation observed during the hand, foot and face/tongue motor tasks maps to its expected locations along the pre- and post-central gyri.All tested language paradigms produced reliable language related cortical activation. Language is left dominant.There are 2-3 foci of activation within the pars opercularis and pars triangularis of the left inferior frontal lobe, any or all of which could represent Broca's area cortical activity. There are 1-2 foci of activation along the left posterior superior temporal gyrus, which likely represent Wernicke's area cortical activity. Strong secondary language activation is seen in the left middle frontal gyrus and at the level of the SMA.
Sensorimotor cortical activity maps as expected along the pre- and post-central gyri.Language is left dominant. Broca's area is identified as expected in the left inferior frontal lobe. Wernicke's area is identified as expected along the posterior aspect of the left superior temporal sulcus.
