Neuroscience Lecture 21: Cerebellum

What are the four functions of the cerebellum?

1. Fine movement coordination

2. Sense of body position

3. Balance

4. Motor learning

What segment of the cerebellum is for equilibrium and eye movement?

Vestibulocerebellum

What segment of the cerebellum receives proprioceptive input from the motor cortex?

Spinocerebellum

What segment of the cerebellum interacts with the motor cortex in planning and programming movements?

Cerebrocerebellum

Where do axons of the deep cerebellar nuclei cross?

Midbrain

Where do axons of the deep cerebellar nuclei and the vestibulocerebellar cortex project to?

Medial ventral horn of the spinal cord

What is formed by the deep cerebellar nuclei and their excitatory afferents?

Deep excitatory loop

What shapes the output of the deep excitatory loop?

Cortical inhibitory loop

What condition causes difficulty reaching for things from damage to the cerebellum?

Appendicular ataxia
