Hess. Primate translational vestibuloocular reflexes. I. High-frequency
dynamics and three-dimensional properties during lateral motion. J. Neu-
rophysiol. 83: 1637­1647, 2000. The dynamics and three-dimensional
(3-D) properties of the primate translational vestibuloocular reflex
(trVOR) for high-frequency (4­12 Hz, 0.3­0.4 g) lateral motion were
investigated during near-target viewing at center and eccentric targets.
Horizontal response gains increased with frequency and depended on
target eccentricity. The larger the horizontal and vertical target eccen-
tricity, the steeper the dependence of horizontal response gain on
frequency. In addition to horizontal eye movements, robust torsional
