Abstract(in Japanese) (See Japanese page)
Abstract(in English) Eye contact is cue behavior to make communication smooth. Many studies have shed light on the perceptual aspect of eye contact, however, little is known about how brain works during it. To elucidate physiological mechanisms underlying eye contact, we trained a macaque monkey to make eye contact with human, and recorded neuronal activity from the premotor cortex (PM) during the eye contact behavior. Some PM neurons enhanced their firing rate during the eye contact, and some PM neurons showed larger responses to the eye contact in a more communicative situation. These results suggest that PM neurons are involved in eye contact behavior in primates.
