The vestibulo-ocular reflex (VOR) has been a popular model system for the study of cerebellar motor control and learning. The VOR maintains a stable visual image on the retina by counter-rotating the eyes during head movements. Perfect compensation is represented by a gain equalling 1.0 where gain is defined as eye velocity/head velocity. In normal conditions, VOR gain is close to 1.0, however in the laboratory, VOR gain can be modified by using visual-vestibular mismatch stimuli. The cerebellum is intimately involved in VOR gain modification as evident in the firing modulation of its output neurons, Purkinje cells, which closely corresponds to changes in VOR gain. Currently we recorded from cerebellar Purkinje cells during a novel VOR motor learning paradigm in which VOR gains at two different stimulus frequencies are modified in opposite directions. We show that while behavior can be simultaneously modified at both stimulus frequencies, Purkinje cells change their firing modulation at only one. |
