[μλ¬Έ]It is often observed that Broca''s aphasics have more difficulties in processing verbs than concrete nouns. On the contrary, Wernicke''s aphasics have more difficulties in processing concrete nouns than verbs. However, these results are often inconclusive and anecdotal. Some investigators have found that both types of aphasic patients were more impaired in producing verbs than nouns. / However, different cerebral localizations of lesions for noun vs. verb impair- ments have been suggested. Patients with a selective disorder for noun usually have lesions centered in the left temporal lobe. Conversely, verb deficits have been associated with left frontal lobe. However, not all the data support the claim for neural specialization of nouns and verbs. Thus, the objectives of the present study were to ascertain whether verb or noun deficits are associated with a particular type of aphasia, and to ascertain whether there are differences in the sites of brain damage. The results were as follows:/1. The mean naming performance obtained by Broca''s and Wernicke''s aphasia groups on verbs was lower than their performance on nouns. However, only Broca''s aphasics were significantly more impaired on verb than noun naming. And Wernicke''s noun naming was significantly poorer than Broca''s noun naming.//2. All of the patients with severe noun deficits have lesions in the left middle-inferior temporal lobules, but patients with verb deficits did not reveal common lesions. //Thus, verb deficits were not unique features for Broca''s aphasia and significant noun deficits were found only in Wernicke''s aphasia. /It is noteworthy that all of the patients with noun deficits had lesions essentially involving the left middle-inferior temporal lobule, indicating neuroanatomical correlates of noun processing. /There are restrictions on limited subjects and tasks in this study, therefore studies considering types and severities of aphasic patients should be followed.ope
