Most of the output from the cerebellum comes from
|
|
Purkinje cell axons
|
|
|
Axons of cells in the deep nuclei
|
|
|
Mossy fibers
|
|
|
Climbing fibers

Explanation:
Detailed explanation-1: -The deep cerebellar nuclei (DCN) consist of three nuclei: the fastigial (medial) nucleus, the interposed nucleus and the dentate (lateral) nucleus. Together they form the sole output of the cerebellum.
Detailed explanation-2: -Besides a motor function, it has been suggested that the cerebellum, and therefore also the deep cerebellar nuclei, are involved in cognitive and linguistic processing as well.
Detailed explanation-3: -The axons of Purkinje cells form the only output from the cerebellar cortex. Axons of the Purkinje cells end in cerebellar nuclei (dentate, emboliform, globose, fastigial) and vestibular nuclei and has an inhibitory effect (gama-aminobutyric acid, GABA) on them.
