Abstract
The vestibular nuclei receive vestibular-related information from canal and otolith afferents as well as from the vestibulocerebellum. In addition and in contrast to other sensory systems, early vestibular processing is highly convergent and strongly multimodal. Notably, the vestibular nuclei receive substantial visual, somatosensory, and oculomotor inputs. Multimodal interactions, which also occur elsewhere in the central vestibular pathways, are vital for spatial perception and for gaze and postural stabilization. Because oculomotor signals play an important role in shaping the information encoded centrally, knowledge of how the brain controls eye movements is crucial for understanding vestibular processing. This chapter provides an overview of oculomotor processing. Topics discussed include an overview and classification of eye movement types, ocular structure and functional implications, gaze redirection, gaze stabilization, and interactions between eye and head movements.
