Methods： Twelve healthy right-handed female subjects completed the study. Each patient performed a jaw-tapping task and an n-back task during functional magnetic resonance imaging （fMRI）. The subjects were trained to carry out the jaw-tapping movement at home twice a day for 4 weeks. The fMRI was repeated when they returned. Results： During the first and second jaw-tapping session, both sides of precentral gyrus and the right middle frontal gyrus （BA 6） were activated. And during the second session of the jaw-tapping task, parts of frontal lobe and temporal lobe related to memory function were more activated. In addition, the total percent task accuracy in n-beck task significantly increased after 4 weeks of jaw- tapping movement. After jaw-tapping training for 4 weeks, brain areas related to memory showed significantly increased blood oxygen level dependent signals. Conclusion： Jaw-tapping movement might be a useful exercise for stimulating the memory and cognitive regions of the brain.展开更多
