| Outline of Final Research Achievements |
In order to examine the functional correlation of parafunction, esophagus and stomach that based the correlation of brain and gastrointestinal tract, we first investigated the morphologic functional characteristic of the stomatognathic system, and a psychological characteristic, in addition to the brain activity. We examined a masticatory muscles activity and a psychological evaluation and a brain activity, during stress task and during fist clenching assumed unconscious clenching. As a result, the masticatory muscles activity increased at each task, and the VAS scores were high. We reported that the experimental acid stimulation to esophagus cause increase of the masticatory muscles activity during awake. Furthermore, an insula and anterior cingulate cortex (ACC), were reported to activate by the stimulation to esophagus, were also activated in this study. Therefore, it suggested that an insula and ACC were related to unconscious clenching such as the awake bruxism.
