Title: EFFECTS OF BILATERAL FLOCCULECTOMY ON OPTOKINETIC (OKN), VESTIBULO-OCULAR REFLEX (VOR) AND VISUO-VESTIBULAR INTERACTIONS IN THE CAT.
Abstract: This chapter discusses the effects of bilateral flocculectomy on vestibulo-ocular reflex (VOR) and visuo-vestibular interaction. The density of connections between the cerebellar flocculus and the anatomical structures subserving the VOR suggests an important contribution of the flocculus to the control of eye movements induced by vestibular stimulation. The flocculus receives mainly afferents from primary and secondary vestibular neurons, extraocular muscle proprioceptors, and the visual system. The experiment explained in the chapter involves recording horizontal and vertical eye movements using the search-coil technique. The optokinetic stimulus is a random dot pattern projected on a hemispherical screen at a constant velocity. Animals are tested before and after bilateral flocculectomy is performed under visual control through a dissecting microscope.
