Schematic of different head and eye movement tasks. A) Eye saccade task: subjects shifted gaze using eye movements only when target moved ±10° from midline at random 3 to 6 s intervals. B) Gaze saccade task: subjects shifted gaze using head and eye movements when target moved ±40° and ±50° from midline at random 3 to 6 s intervals. C) Gaze stabilization task: subjects fixed gaze on stationary target while moving head at 0.25 Hz. D) Gaze pursuit task: subjects viewed target as it moved from central viewing area of display to 60° left and right of midline.
