The cerebellum in eye movement control: nystagmus, coordinate frames and disconjugacy

In this review we discuss several aspects of eye movement control in which the cerebellum is thought to have a key role, but have been relatively ignored. We will focus on the mechanisms underlying certain forms of cerebellar nystagmus, as well as the contributions of the cerebellum to binocular alignment in healthy and diseased states. A contemporary review of our understanding provides a basis for directions of further inquiry to address some of the uncertainties regarding the contributions of the cerebellum to ocular motor control.
