Suppressive responses by visual food cues in postprandial activities of insular cortex as revealed by magnetoencephalography

Abstract ‘Hara-Hachibu’ in Japanese means a subjective sense by which we stop eating just before the motivation to eat is completely lost, a similar concept to caloric restriction (CR).

Description
Summary:Abstract ‘Hara-Hachibu’ in Japanese means a subjective sense by which we stop eating just before the motivation to eat is completely lost, a similar concept to caloric restriction (CR). Insular cortex is a critical platform which integrates sensory information into decision-making processes in eating behavior. We compared the responses of insular cortex, as assessed by magnetoencephalography (MEG), immediately after presentation of food images in the Fasting condition with those in the ‘Hara-Hachibu’ condition. Eleven healthy, right-handed males [age, 27.2±9.6 years; body mass index, 22.6±2.1 kg/m2 (mean±SD)] were enrolled in a randomized, two-crossover experiment (Fasting and ‘Hara-Hachibu’ conditions). Before the MEG recordings in the ‘Hara-Hachibu’ condition, the participants consumed rice balls as much as they judged themselves to have consumed shortly before reaching satiety. During the MEG recordings, they viewed food pictures projected on a screen. The intensities of MEG responses to viewing food pictures were significantly lower in the ‘Hara-Hachibu’ condition than those in the Fasting condition ( P
