Abstract

In five alert chronically-prepared cats we studied the response to sinusoidal 3-D whole body rotation of well-isolated vestibular nucleus neurons which were tested for monosynaptic input from the vestibular labyrinth, direct projection to the oculomotor nucleus and, in some cases, inhibition from cerebellar flocculus stimulation. Neurons directly inhibited by flocculus stimulation had significantly greater horizontal-vertical semicircular canal signal convergence than did neurons not inhibited by flocculus stimulation.
