Abstract
Previous studies indicate that the hippocampus is active during exercise, and that neurotrophin expression, receptor density, and survival
of dentate gyrus granule cells in the hippocampus can be modified by moderate voluntary exercise. The present study was designed to test the
consequences of voluntary exercise on a hippocampal-related behavior. Exercising and control rats were tested on the standard and delayed
nonmatch-to-position (DNMTP) version of the eight-arm radial maze, both of which are sensitive to hippocampal damage. Voluntarily
exercising rats ran in running wheels attached to their home cage for 7 weeks prior to and throughout testing, and took 30% fewer trials to
acquire criterion performance than sedentary controls. Both groups spent the same average time per arm. Once the eight-arm maze had been
