| Research Abstract |
A low intensity exercise without stress enhanced adult hippocampus neurogenesis (AHN), while the effect disappeared by a high intensity exercise with stress. Furthermore, it became clear that low intensity exercise induced AHN via corticosterone (CORT) pathway and found that inhibitory effect of glucocorticoid receptor (GR) became dominant in the high intensity exercise. It was suggested that CORT took an important role in specific effect of exercise intensities on hippocampal plasticity.
