Cerebellum and cerebrum in adaptive control and cognition: a review

There have been various descriptions of cerebellar function in terms of adaptive control. However, a number of recent publications have indicated that the cerebellum is involved in a range of cognitive processes including pure cognitive activity. This review paper relates the concept of cerebellar adaptive control to cerebellar cognition, and explores the relative roles of the cerebrum and cerebellum by considering the issue of representation and processing of information in a systematic manner. It is suggested that the cerebellar cortex and cerebral cortex facilitate two fundamentally different types of information representation and processing which are complementary and which should be able to reciprocally evaluate and correct each other, thereby providing the basis for a self-correcting adaptive control system.
