Female, 39 years old, with intractable epilepsy. Functional MRI requested for localization of speech and sensorimotor cortex. Sensorimotor cortical activation maps as expected along the pre- and postcentral gyri.All tested language paradigms produced reliable language related cortical activation. Language is left dominant with minor task dependent contributions from the right hemisphere.Broca's area activity is identified within the inferior left frontal lobe, principally involving the pars opercularis and to a lesser degree the pars triangularis.Wernicke's area activity is identified most reliably on the sentence completion paradigm where it is visualized along the posterior aspect of the left superior temporal sulcus.
Successful functional MRI for surgical planning. Sensorimotor cortical activation maps as expected along the pre- and postcentral gyri. Language is left dominant with minor contributions from the right hemisphere. Broca's and Wernicke's areas are identified in their customary locations.
