The cerebellum is known to improve but not generate eye movements. Thus without the cerebellum all types of eye movements are still possible, an exemption being smooth pursuit eye movements (SPEM) which can no longer be performed after total cerebellectomy (Westheimer and Blair, 1973). It is also well established that certain areas of the cerebellum are more involved in oculomotor control than others. Three major cerebellar structures related to oculomotor functions have been distinguished: I. The floccular region, II. the oculomotor vermis with the underlying fastigial nucleus and III. the nodulus. However, there are certainly other structures of the cerebellum, which are also involved in oculomotor control (Ron and Robinson, 1973; Mano et al. 1991; Straube et al. 1997). In the following some recent results concerning the role of the cerebellum in oculomotor control will be presented. Emphasis will be laid on the relation of structure and function. However, in patient studies this is often not possible in detail.
