Cerebellar mechanisms of learning and plasticity revealed by delay eyelid conditioning

Int Rev Neurobiol. 2014:117:21-37. doi: 10.1016/B978-0-12-420247-4.00002-6.

Abstract

The analysis of well-defined behaviors that require the cerebellum has helped reveal many key mechanisms operating in the cerebellum to mediate learning and feed-forward prediction. These systems include eyelid conditioning, adaptation of the vestibuloocular reflex, smooth pursuit eye movements, and arm-reaching tasks. This review focuses specifically on the variety of findings that have come from the use of eyelid conditioning to study the cerebellum. Phenomena discussed include sites and rules for plasticity, temporal coding and mechanisms of timing, cerebellar control of climbing fibers and its role in bidirectional learning, extinction of conditioned responses, and the phenomenon of savings.

Keywords: Cerebellum; Conditioning; Extinction; Long-term depression; Long-term potentiation; Savings; Timing.
