Abstract
The proportions of crouching responses after shock and the number of passive avoidance errors were compared for 30 rats with lesions in the hippocampus, septum, or cingulum and 30 controls. Hippocampal lesioned Ss made fewer crouching responses and were poorer in passive avoidance. Septal lesions disrupted both crouching and locomotion but did not alter passive avoidance. The cingulate lesioned Ss were poorer on passive avoidance but their crouching decrease was not statistically significant. The results indicate that lesion produced disruptions of crouching may influence passive avoidance performance. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
