Cerebellar cortex

Abstract

The cerebellar cortex appears to be involved in predictive feedforward control to generate smooth movements. There is a beautiful network architecture which suggests that the granule cells perform expansion recoding of the inputs; that these connect to the Purkinje cells via an architecture that ensures regular sampling; and that each Purkinje cell has a single teacher, the climbing fibre, which produces associative long-term synaptic depression as part of perceptron-like learning.
