Outline of Final Research Achievements

We validated a Japanese version of questionnaire, Power of Food Scale (PFS), to measure the motivation to eat beyond physiological need. Next, we determined brain areas related the motivation to eat and examined individual variability using magnetoencephalography (MEG) during the presentation of food images in the fasting or Hara-hachibu conditions. We demonstrated the involvement of immediate neural responses of the insular cortex in individual differences in motivation to eat in both dietary conditions. Furthermore, we demonstrated that non-exercise lifestyle is associated with motivation to eat, raising the possibility that such distorted and inevitable motivation (urge) to eat and the underlying brain activities might be suppressed even by infrequent exercise habit.
