| Research Abstract |
Brain blood flow during masticatory movement, finger tapping and hand holding increased for all three movements, and the amount of change was the largest for masticatory movement. Brain blood flow during chewing three types of gummy-jelly with different amount of bitterness also increased for all three types of gummy-jelly, however the amount of blood flow decreased as the bitterness increased. From these results, it was concluded that masticatory movement stimulates brain activities more than other body movements, and the difference in the taste of food affects brain blood flow.
