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 |
