Abstract：
:Eye and head movements during tracking of a smoothly moving visual target were recorded in trained monkeys. The head movement clearly followed the target, although with considerable variability from cycle to cycle. The eye stayed relatively near the primary position and moved in an apparently irregular fashion; however, the sum of eye and head, or gaze, remained accurately on target despite the irregularity of the individual eye and head movements. When compared with tracking with head fixed, head free tracking was not measurably different in accuracy. Further experiments were performed which demonstrated a role for the vestibular system in coordinating eye and head during smooth pursuit. The results of these experiments can be best explained by postulating an internal smooth pursuit command driving both eye and head movements. In the case of the eye movement, this smooth pursuit command is combined with vestibular feedback from head movement before being forwarded to eye movement centers.
