| Abstract | Brain areas involved in gaze monitoring were determined using positron emission tomography (PET) in the present study. Healthy normal volunteers measured regional cerebral blood flow during gaze direction discrimination tasks. A region in the left amygdala was activated during eye-contact and no eye-contact tasks to the same extent. However, a region in the right amygdala was specifically activated only during the eye-contact task. Our results indicate that the left amygdala plays a general role in the interpretation of eye gaze direction, and that the activity of the right amygdala of the subject increases when another individual's gaze is directed towards him. |
