| Outline of Final Research Achievements |
Subjects were asked to watch food or mosaic pictures (5 min) and to close their eyes (3 min) before and after the picture presentation without thinking of anything. Resting brain activities were recorded for both eye-closed sessions. The brain activities were changed after the visual presentation in insula (IS), dorsolateral prefrontal cortex (DLPFC), and frontal pole. The changes of activities in IS and DLPFC were associated with feeling of pleasure in eating food in dietary life, and those in frontal pole were associated with increases in appetitive motives during the experiment. These findings raise the possibility that automatic or unconscious brain mechanisms after food-related stimulation might determine subsequent eating behaviors through positive emotion such as pleasure in eating and irresistible appetitive motives. The result suggests importance of elucidation of these brain mechanisms in order to develop efficient strategies for optimizing dietary lifestyle in modern people.
