摘要: Verbal phonological and semantic fluencies were investigated in 24 patients with unilateral prefrontal lesions 10 normal control subjects. Lesions limited to small areas within either the dorsolateral (Brodmann's area 46/9) or ventromedial (posterior part of gyrus rectus) cortices. In a fluency task, left region impaired. fluency, not only group but also two right frontal damaged groups performed worse than group. agreement previous studies, our results show that is mediated by cortex. contrast this, performance on task depends wider portion cortex involving areas.
