In this article, we review a broad range of studies of cerebellar function and dysfunction and interpret them within the framework that the cerebellum acts as part of a mechanism of predictive control. We describe studies that span human behaviour and consider the motor and sensory impairments that result from cerebellar damage. We conclude that a parsimonious explanation of cerebellar function is as a predictor of the sensory outcomes of movement. However, future studies are needed to more rigorously test this hypothesis and determine how the cerebellar circuit might perform this type of computation.
