| Outline of Research at the Start |
We will use electrophysiological recording techniques, in combination with a behavioral task that helps identify positive motivational behavior to reveal the brain activities and structures that accompany the motivational benefits of the non-stressful mild-running exercise paradigm in rats.
|
| Outline of Annual Research Achievements |
During this project, we have developed techniques to do multi-site local field potentials in rats before, during, and after a light running exercise to identify the positive effects of this exercise on brain activities and structures related to positive motivation. We have recorded different brain parts, including the hippocampus (CA1) and cortex. I confirmed that light running increased theta activity up to 6 times. It also increased waking periods following exercise by up to 90 minutes. This demonstrates a general activating effect of light running. Hippocampal theta waves have been shown to be involved in physical activity, cognitive processes, and memory formation and recovery, so these results strongly support the hypothesis that light exercise positively impacts brain activity.
