Region of Cerebellum
Anatomical Location
Pathway
Origin
Peduncle
Input
Deep Cerebellar Nuclei
Output
Vestibulocerebellum
(Archicerebellum)
Balance
Flocculonodular lobe
Vestibulocerebellar
Vestibular Nuclei
Inferior
Mossy fibres
Fastigal Nuclei
Vestibular nuclei and reticular formation of medulla, and onto vestibulospinal and reticulospinal tracts
Spinocerebellum
(Palecerebellum)
Muscle Tone and posture (propriception)
Ipsilateral vermis and paravermis
Spinocerebellar
Dorsal and ventral spinocerebellar tracts (via clark’s nucleus)
Inferior
Mossy Fibres
Globose and emboliform
Red Nucleus of the midbrain, and onto the rubrospinal tract.
Cerebrocerebellum
(Neocerebellum)
Majority of the cortex of the cerebellum
Pontocerebellar
Pontine nuclei (at basal part of pons)
Middle
Mossy Fibres
Detate
Most go to contralateral ventral lateral nucleus of thalamus, and onto the primary motor cortex to act on the corticospinal and coritobulbar tracts
