| Outline of Final Research Achievements |
Accumulating evidence suggested that physical exercise improves various brain functions, including memory and learning, emotion and cognitive/executive functions. The multiple effects of exercise on the brain function may be due to interaction of neural activation of multiple brain regions stimulated by exercise. In the present study, we tried to identify the functional brain network recruited by acute treadmill running in male Wistar rats, using c-Fos immunohistochemistry and correlation analysis. We found that the functional brain network recruited by exercise was formed depending on exercise intensity, and that chronic regular exercise could remodel the functional brain network recruited by acute exercise. These results suggest that the functional brain network recruited by exercise, which is defined by co-activation of multiple brain regions, may depend on intensity and duration of the exercise.
