vestibulocerebellum

The phylogenically oldest part of the cerebellum, which regulates balance and eye movements.

Anatomic components
Flocculonodular lobe and adjacent vermis.

Receives
• Vestibular input from semicircular canals and vestibular nuclei;
• Visual input from superior colliculi and visual cortex via pontine nuclei, forming a cortico-ponto-cerebellar pathway.

Sends
To medial and lateral vestibular nuclei.

Lesions
Cause disturbances of balance and gait.
