Modulation of Movement by the Cerebellum - Projections from the Cerebellum

3 important questions on Modulation of Movement by the Cerebellum - Projections from the Cerebellum

Why do projections from the cerebellum to the cortex need to cross the midline?

Because the cerebellum receives information from the ipsilateral side of the body, while the cortex only processes contralateral information. So information from the cerebellum needs to cross the midline for the cortex to process contralateral information.

What feedback circuit is crucial for the adaptive function of the cerebellum?

Projections from the cerebellum to cortex send collaterals to the inferior olive via the red nucleus.

Via what structure does the cerebellum have acces to the premotor cortex?

The thalamus
