Connections

Input

From three sources, vehiculated via the middle and inferior cerebellar peduncles:

  • Vestibular
  • Ascending
  • Descending

Note:

All input coming from the cerebral cortex crosses the median line before arriving to the cerebellum. Therefore, the cerebellum processes informations coming from the ipsilateral hemicorpus.

Within the cerebellum

Projection on deep cerebellar nuclei

Output

Four sources, exiting through the superior and inferior cerebellar peduncles:

  • Vestibulocerebellum
    function: balance and oculovestibular regulation
  • Dentate nuclei
    function: planning of movements
  • Interposed nuclei
    function: execution of movements
  • Fastigial nuclei
    function: execution of movements

Feedback loops

  • Via the inferior olivary complex
  • Via the vestibular nuclei
