Three-Dimensional Primate Eye Movements during Lateral Translation
Natural head movements provide a rich vestibular stimulus containing both rotational and translational components. Reflexive eye movements elicited by head motion provide a unique opportunity to study sensorimotor function. The oculomotor response to linear motion (translational vestibulo-ocular reflex, TVOR) is kinematically more challenging than that to rotation. In general, compensatory eye movements during translational motion are different for each eye and exhibit a dependence on the position of the target of interest. The distance of a desired fixation point also imposes kinematic requirements on the TVOR (Virre et al. 1986; Paige 1989, Schwarz et al. 1989, Paige and Tomko 1991a,b; Schwarz and Miles, 1991, Snyder and King 1992, Telford et al. 1997).
