Head movement control during head-free gaze shifts.
Humans mostly use combined eye-head movements to shift gaze to a new target. Here, we discuss head motor control during human gaze shifts. We demonstrate that vestibular feedback monitors and guides the head movement on-line. Our results further suggest that cerebellar signals play a role in this on-line control, possibly by contributing to detect vestibular input indicating deviations from the intended movement trajectory.
