Outline of Final Research Achievements

The purpose of this study is to devise an exercise program to improve brain function using jaw movement. For this purpose, cerebral blood flow dynamics (brain activity) when changing the jaw motion (gum chewing movement, clenching movement, opening / closing movement) conditions were measured by the brain functional imaging method (functional near infrared spectroscopy). As an exercise condition, the gum chewing movement and open / close movement were normal speed and slightly faster exercise, the clenching movement was light and moderate strength. As a result, movement with a slightly faster or moderate intensity as a condition increased the activity of the dorsolateral prefrontal cortex associated with working memory and the frontal pole associated with decision making.
