Models of the cerebellum and motor learning

Houk, James C., Buckingham, Jay T. and Barto, Andrew G. (1996) Models of the cerebellum and motor learning.

Short Abstract:

This article reviews models of the cerebellum and motor learning starting with the landmark papers by Marr and Albus and going through present times. The unique architecture of the cerebellar cortex is ideally suited for pattern recognition, but how is pattern recognition incorporated into motor control and learning systems? The present analysis begins with a discussion of what the cerebellar cortex needs to regulate through its anatomically defined projections to premotor networks. Next we examine various models of how the microcircuitry in the cerebellar cortex may be used to achieve its regulatory functions. Having thus defined what it is that Purkinje cells in the cerebellar cortex must learn, we then evaluate theories of motor learning. We examine current models of synaptic plasticity, credit assignment and the generation of training information, indicating how they could function cooperatively to guide the processes of motor learning.
