It is the largest of the four deep cerebellar nuclei, the others being the [[fastigial nucleus]] and the [[interposed nucleus]] (globose and emboliform nuclei combined). It is responsible for the planning, initiation and control of volitional movements. It therefore receives its afferents from the [[premotor cortex]] and the [[supplementary motor cortex]] (via the [[pontocerebellar system]]). Its efferents project via the [[superior cerebellar peduncle]] to the contralateral [[red nucleus]] and ventrolateral [[thalamus]] (crossing over at the pontomesencephalic junction). It consists of an irregularly folded [[lamina]], of a grayish-yellow color, containing white fibers, and presenting on its antero-medial aspect an opening, the [[hilus]], from which most of the fibers of the [[superior peduncle]] emerge. ==Additional images== <gallery> Image:Gray683.png|Dissection of brain-stem.
