Abstract

Extracellular microelectrode recordings from single cerebellar neurons were made in the ventral paraflocculus of anesthetized, paralyzed pigmented rabbits during vestibular and visual stimulation. The discharge of 6 out of 207 neurons was modulated during vestibular or visual stimulation. The activity of 5 neurons was modulated during vertical vestibular stimulation. The discharge of only one neuron was modulated exclusively during vertical optokinetic stimulation. The information from both the vestibular and visual systems which is received by the ventral paraflocculus appears to differ from that which is received by the flocculus in rabbits.
