Effects of adrenal demedullation and stria terminalis lesions on retention of an inhibitory avoidance response

Abstract

The present study investigated the effects of adrenal demedullation and/or lesions of the stria terminalis (ST) on retention of an inhibitory avoidance response. The results of Experiment 1 indicate that adrenal demedullation results in impaired retention when low footshock is used for training. The results of Experiment 2 indicate that ST lesions produce, at best, only a mild retention deficit. The results of Experiment 3 indicate that adrenal demedullation does not potentiate the effect of ST lesions on retention.
