Document Summary

The flocculonodular lobe of the cerebellum receive its input from the vestibular system and the visual system. The main function of the vermis and the intermediate hemispheres is to control the actual execution of movement (correct for deviations from an intended movement through comparing feedback from the spinal cord with the intended motor command), The three phylogenetic zones of the cerebellum and their functions are: The flocculonodular lobe (vestibulocerebellum: controls the axial muscles, used in equilibrium control. The vermis and intermediate hemispheres (spinocerebellum: control the actual execution of movement, modulate muscle tone, regulate movements using a feedforward mechanism. The vermis and intermediate hemispheres of the cerebellum would help prevent a person from overshooting a target through a feedforward mechanism. Movement is not required to activate the cerebellum. The functional differences between the cerebellum and the basal ganglia: the basal ganglia is concerned with internally generated movements, while the cerebellum is involved in visually triggered and guided movements.
