Abstract

In alert, chronically-prepared cats, we studied response characteristics of well-isolated vestibular nucleus neurons (n = 9) while pairing yaw rotation with a pitch optokinetic stimulus, resulting in cross-axis adaptation of the horizontal vestibulo-ocular reflex. Each neuron's sensitivity to whole body rotation in a variety of axes in three-dimensional space was determined. When tested in darkness following adaptation, neurons showed statistically significant increases in sensitivity to yaw but not vertical plane rotations, suggesting participation in reflex plasticity.
