Summary

This chapter focuses on some of the tasks that the cerebellum performs. It describes some possible cerebellar mechanisms that could carry out timing functions for each task. Models like Mauk's are not constrained to be linear. The chapter explores some simpler models and many of the concepts related to timing that will rely on linear filters. Linear models of cerebellar function, as well as the neural-network models, assume that the important signals are neuronal discharge rates, that is, scalar variables that are continuous functions of time. However, changes in the discharge rate may be too gradual to do the job of timing in some cases. The pattern of activity in the cerebellum has two features. They may be of key importance in motor timing and coordination. These features are synchrony among the climbing fibers, and synchrony of the simple spikes that convey information out of the cerebellar cortex.
