The nucleus of Darkschewitsch is an accessory oculomotor nucleus situated in the ventrolateral portion of the periaqueductal gray of the mesencephalon (midbrain): 114 : 458.e1 near its junction with the diencephalon. It is involved in mediating vertical eye movements. It projects to the trochlear nucleus, receives afferents from the visual cortex, and forms a reciprocal (looping) connection with the cerebellum by way of the inferior olive.
Anatomy
= Connections
=It receives afferents from the visual association areas (via the corticotectal tract),: 241 vestibular nuclei (via the medial longitudinal fasciculus),: 402 and from the spinomesencephalic tract.: 433.e1
It gives rise to the medial tegmental tract to project efferents to the (rostral portion of) medial accessory olivary nucleus: 458.e1 → ((decussation) inferior cerebellar peduncle → (contralateral) globose nucleus of cerebellum → superior cerebellar peduncle (decussation) → (rostral part of) medial accessory olivary nucleus → (ipsilateral) nucleus of Darkschewitsch: 484 ).
It projects (directly or indirectly) to the trochlear nucleus.: 457
= Relations
=It is situated near the oculomotor nucleus.: 321 It is situated just dorsomedial to the interstitial nucleus of Cajal, the medial longitudinal fasciculus, and red nucleus.: 458.e1
