Abstract: Experiments conducted in animals have repeatedly demonstrated the ability of exercise to enhance cognitive function.This study examines the effects of chronic swimming exercise on non-spatial memory in adult rats after 12 weeks of swimming exercise in object recognition and elevated T-maze tests.In the object recognition test, repeated measures analysis of variance revealed a group effect (F 1,42 = 26,093; p < 0.001), control rats had lower discrimination ratios than the exercise group.However, the swimming exercise did not affect the performance of inhibitory avoidance and escapes, when memory was tested in elevated T-maze.Analysis of variance showed a significant reduction in inhibitory avoidance 24h after the first training (F 1,42 = 14,552; p < 0.001).Results indicated that regular swimming exercise significantly increased non-spatial memory in object recognition behavior, but did not affect the performance of inhibitory avoidance and escape on elevated T-maze test in adult rats.These findings suggest that the perirhinal cortex plays a role in memory consolidation and storage in addition to that of the amygdala, which could be regarded as the center of a second memory system, separate from those governed by the perirhinal cortex.
