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 |
