Theories on cerebellar mechanisms are presented, based on the cerebellum's multiple excitatory and inhibitory interconnections. In animals, the results of responses to distant stimuli, direct stimulation, and ablation are reviewed, with differences between subprimates and primates explained. The relationship between the cerebellum, muscle spindles, and hypotonia is also discussed.
