The largest of the four deep cerebellar nuclei, a region where the cell bodies of neurons involved in the planning, initiation, and control of volitional movements are clustered. The other nuclei are the emboliform, globose, and fastigial nuclei. These deep cerebellar nuclei are in the centre of the cerebellum, embedded in the white matter, and are the origin of most of the output fibres of the cerebellum. They receive inhibitory inputs from Purkinje cells in the cerebellar cortex and excitatory inputs from mossy fibre and climbing fibre pathways.
