Male, 17 years old, with epilepsy. Pre-surgical language localization is requested. Sensorimotor cortical activation maps as expected along the pre- and post-central gyri.All tested language paradigms produced reliable language related cortical activation, though Wernicke's area is visualized only on the sentence completion paradigm. Language is left dominant.Putative Broca's area activity is seen in the left inferior frontal lobe (predominantly pars triangularis). Putative Wernicke's area activity maps along the posterior aspect of the left superior temporal sulcus.
Successful fMRI for language lateralization. Language is left dominant. Broca's and Wernicke's areas map to their expected locations as above.
