All language paradigms produced reliable language related cortical activation. Language is left dominant. Broca's area is identified as several foci of activation in the left inferior frontal lobe, primarily pars triangularis. Wernicke's area is identified as one or two foci of activation along the posterior aspect of the superior left temporal gyrus.
Successful functional MRI for language lateralization. Language is left dominant.
