- Uppermost portion of cerebellum, which receives sensory information about the relative location of different body parts and anticipates movement 
- Damage results in ataxia, which causes a loss of coordination of the elgs, as well as a loss of gait and posture 
- Long term alcoholism can degrade anterior lobe of cerebellum, causing disrupted gait

Smith College

- The cerebellum's three major subdivisions are responsible for specific functions, which can cause specific motor and (subsequent) behavioral impairments when damaged 
- These subdivisions include the spinocerebellum, cerebrocerebellum, and vestibulocerebellum

Spinocerebellum

- Lowermost portion of cerebellum
- Involved in coordinating complex movements 
- Damage can cause decomposition of movements, known for stilted/ broken up/ non-smooth movements 

Cerebrocerebellum 

- In between the two other regions of the cerebellum
- Obtains information about spatial orientation of body, and supports ability to regulate posture and direct eye movement  
- Damage to this region causes a difficulty in following objects visually as the head moves, and general use of visual field (gaze)
