Assessment of the effects of cinglulate gyrus lesions by neuropsychological techniques.
Nineteen psychiatric patients undergoing bilateral cryogenic cingulate cortex lesions were extensively evaluated pre- and postoperatively with objective measures of intelligence, higher cortical functions, memory, and emotional status. Following surgery the patients as a group revealed no significant deterioration of functions; rather, they demonstrated improvement that could be interpreted as the result of decline in anxiety. Investigations of individual revealed that the overall test performance was improved in 13 and substantially unchanged in three, whereas three demonstrated some decline in performance. These results were discussed in terms of the characteristics of the changes across the various tests.
