Experiment to determine brain activation in response to expected and unexpected gaze shifts on the part of another person (left panel) and corresponding brain activation to biological motion (observed human movements; right panel). Incongruent trials evoked greater right hemisphere STS activity than did congruent trials, demonstrating the sensitivity of the STS region to the intentions conveyed by eye-gaze shifts.
