1. The vestibuloocular reflex (VOR) stabilizes images on the retina against movements of the head in space. Viewing distance, target eccentricity, and location of the axis of rotation may influence VOR responses because rotation of the head about most axes in space rotates and translates the eyes relative to visual targets. To study the VOR response to(More)
The objective of these experiments was to determine whether the trajectories of the horizontal and vertical components of oblique saccades in primates were coupled. Human and monkey eye movements were recorded during a visual tracking task that jumped a small visible target spot to different locations on a tangent screen. For oblique saccades larger than(More)
The axis of head rotation is usually different from the axis of eye rotation. Geometrical considerations show that the eyes translate with respect to visual targets located near the head. In order to accurately stabilize retinal images against this translation, the vestibulo-ocular reflex (VOR) must be modulated inversely with the target's distance. The(More)
Afferent and efferent connections of behaviorally identified omnipause neurons involved in saccadic eye movements were investigated electrophysiologically in cats anesthetized with ketamine hydrochloride. Pause cells were polysynaptically excited by electrical stimulation of the optic chiasm (mean latency = 8.3 ms), the visual cortex (mean latency = 7.3(More)
1. Four macaque monkeys were trained to fixate visual targets. Eye movements were recorded binocularly using the search coil technique. Saccades, vergence movements, and combinations of the two were elicited by training the monkeys to alternate the gaze between real visual targets that differed in viewing distance and eccentricity with respect to the(More)
Recordings from neurons in the vestibular nuclei indicate that the cells that carry eye position signals encode the position of a single eye (either ipsilateral or contralateral) during both conjugate and vergence eye movements. The fact that the vestibular nuclei are aware of the positions of each eye is not surprising as the otolith-based linear(More)
