The cerebellum is located in the hindbrain and coordinates motor function and muscle tone. It has three functional divisions - the vestibulocerebellum regulates balance and eye movements, the spinocerebellum controls distal and proximal muscle movements like walking, and the corticocerebellum plans sequential movements and speech. Damage to different parts of the cerebellum results in impairments like ataxia, nystagmus, tremors, and difficulties with gait and coordination.

2. Cerebellum
 A region of brain that coordinate motor
function and muscle tone
 Largest part of hindbrain
 Located behind the top part of the brain
stem.
 Called silent area

4. Functional divisions
 Vestibulocerebellum
 Spinocerebellum
 Corticocerebellum

5. Vestibulocerebellum
Inputs:
 From vestibular nuclei in brainstem
Function:
 Regulate movements underlying posture
and equilibrium
 Coordination of eye and head movements
Damage:
 Impairs ability to stand upright, maintain
posture and balance
 Cerebellar nystagmus

6. Spinocerebellum
Inputs:
 Directly from spinal cord
Function:
o Lateral portion
 Movement of distal muscle (ex. gross
movements during walking)
o Central portion (vermis)
 Movement of proximal muscles
Damage:
 Overshoot and intension tremor
 Impaired gait

7. Corticocerebellum
Inputs:
 Many areas of cerebral cortex (relayed thru Pons)
Function:
 Planning and timing of sequential movements
 Speech
Damage:
 Ataxia: Incoordination of complex, purposeful
movements of hands, fingers, feet and speech
apparatus
 Failure of smooth progression of movement
Lesions to any division of cerebellum result in
impairments on ipsilateral side of the body
