The spinocerebellum has a role in

Head and eye movement, corrections of trunk movements, signaling to the forebrain.

How does the excitatory loop of the cerebellum work?

Input form the pontine nuclei, spinal cord and vestibular system --> mossy fibers of the cerebellum --> signal to the deep cerebella nuclear cell --> output

How does the inhibitory look of the cerebellum work?

The mossy fibers signal to the granule cell --> excite the parallel fibers --> send information to the purkinje cells --> the climbing fibers also signal to the purkinje cell  --> inhibition of the deep cerebellar nuclear

What are complex spikes

Combination of climbing and parallel fibers --> parallel fibers get a weak signal --> LTD

A purkinje cell receives .... Of parallel fibers inputs

100000

Each parallel fiber contacts thousands of ...

Purkinje cells

Each climbing fiber contacts ... Purkinje cells
