Abstract

Distal ileum motility was continuously recorded in rhesus monkeys during long-term avoidance conditioning, before and after bilateral cingulum ablation. The results indicated that the diurnal ileum motility patterns were most commonly bimodal and quite regular for individual animals regardless of the conditioning or the lesions. In contrast, the avoidance conditioning did affect the daily motility output of the monkeys. The animals tended to be either hyper- or hypomotile during the avoidance weeks as compared to control weeks. The cingulum monkeys were less consistent in their direction of motility change during avoidance conditioning than those monkeys with cortical control lesions. The cingulum lesions seemed to reverse the ileum-motility output trend evidenced during the pre-lesion avoidance period.
