KEY POINTS

1. The cerebellum constantly compares the intended movement with the actual movement and makes appropriate adjustments.

2. Cerebellar histology and phylogeny give clues to cerebellar function.

3. The vestibulocerebellum helps coordinate balance and eye movements.

4. The spinocerebellum helps coordinate muscle tone as well as limb movement.

5. The Cerebrocerebellum helps with planning coordinated, properly timed movement sequences.

6. The cerebellum plays a role in motor learning.

7. Cerebellar disease causes abnormalities of movement.
