Abstract

Abstract Unilateral and bilateral septal lesions produced: (a) impaired reversal of a T-maze position habit; (b) changes in water consummatory behavior following deprivation; and (c) enhanced shuttle-box avoidance responding. The rats with unilateral lesions were superior to those with bilateral lesions in acquiring the avoidance response, but were intermediate to control rats and rats with bilateral lesions on the reversal task. Some brain mechanisms which could account for these data are discussed.
