- Abstract
- We examined three-dimensional eye positions in alertness and light sleep when monkeys were placed in different roll and pitch body orientations. In alertness, eye positions were confined to a fronto-parallel (Listing's) plane, torsional variability was small and static roll or pitch induced a torsional shift or vertical rotation of these planes. In light sleep, the planes rotated temporally by about 10°, torsional variability increased by a factor of two and the static otolith-ocular reflexes were reduced by about 70%. These data support the importance of a neural control of the thickness and orientation of Listing's plane, and suggest that part of the vestibular input underlying otolith-ocular reflexes depend on polysynaptic neural processing.
