Model of four regions of the cerebellum

The authors propose computationally coherent models of the four regions of the cerebellum based on the feedback-error-learning scheme. They assume that climbing fiber responses represent efference copy of motor commands generated by premotor networks such as feedback controllers at the spinal, brain stem, and cerebral levels. Based on the long-term depression in Purkinje cells, which tends to decrease the premotor-network activity, different regions of the cerebellum learn to execute predictive and coordinative control of different types of movements and complement crude control by the premotor networks
