Nucleus Darkschewitsch ND

This small nucleus is located just rostral and dorsal to the interstitial nucleus of Cajal near the most rostral pole of the oculomotor complex (Fig. 1C). Its relationship to oculomotor control is unclear. It has strong projections to the dorsal cap of Kooy of the inferior olive (which projects to the flocculus of the cerebellum) and receives strong projections from the dentate nucleus of the cerebellum and from the cortex (pre-and postcentral gyrus). The afferents to the nucleus Darkschewitsch from the vestibular nuclei (via the medial longitudinal fasciculus) are small compared to the vestibular input to the interstitial nucleus of Cajal. The nucleus Darkschewitsch is closely associated with both motor (dentate nuclei and precentral gyrus) and oculomotor structures (providing floccular input), and it may participate in some aspects of hand-eye coordination (the dentate mediates control of distal upper limb segmental motoneurons).
