They may seem a little unsettling but the staring eyes of this female avatar were designed to grab your gaze and hold it, and also to obligingly follow where you look. By performing these actions with people placed inside a brain scanner, she has helped to demonstrate that guiding the gazes of others activates different brain areas than following.
The real-time fMRI scans revealed that when the volunteers successfully got the avatar to follow their gaze, brain areas involved in reward and motivation were activated. When they followed the avatar's gaze, a different area of the brain, known to be involved in imagining what other people are thinking, was active.
