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

Detate
|
Most go to contralateral ventral lateral nucleus of thalamus, and onto the primary motor cortex to act on the corticospinal and coritobulbar tracts
