Figure 4c. Areas of activation for the verbal fluency–verb generation paradigm. The subject was a left-handed 42-year-old man with a right hemispheric temporal lobe lesion who presented with headache and speech disorders. T1-weighted MR images show a lesion in the right temporal lobe (arrow in a), an area of superimposed activation in the left inferior frontal gyrus (classic Broca area) (arrows in b), and areas of equal activation bilaterally in the medial temporal gyri (classic Wernicke area) (arrows in c). Conclusions: left hemispheric dominance for language; no relationship between the areas of activation and the lesion.
