Male, 13 years old, with left frontal cortical dysplasia and intractable epilepsy. Functional MRI for surgical planning. Of the tested language paradigms, the most reliable language related cortical activation is seen with the word generation and the verb generation paradigms. Language is left dominant. Wernicke's area is identified in its customary location along the posterior aspect of the left superior temporal sulcus. Cortical activation related to Broca's area is present in the left inferior frontal gyrus, primarily the pars opercularis and the pars triangularis. This activity is well removed from the patient's left frontal focal cortical dysplasia.
Successful functional MRI for language mapping. Language is left dominant. Broca's and Wernicke's areas are identified in their customary locations. Activity related to Broca's area is well removed from the patient's left frontal cortical dysplasia.
