CEREBELLUM

Vestibulocerebellum – floculonodular lobe

Spinocerebellum – Intermediate lobe

Cerebrocerebellum – Lateral lobe

CEREBELLAR FUNCTIONS

1. 1. Planning
   2. Sequencing
   3. Timing
   4. Comparing
   5. Corrective adjustments
   6. Learns by mistakes
   7. Control intensity
   8. Prediction of motor, auditory and visual responses
