The accessory oculomotor nuclei are a group of nuclei situated in the rostral mesencephalon (midbrain) near its junction with the diencephalon, and consist of:

Interstitial nucleus of Cajal Rostral interstitial nucleus of medial longitudinal fasciculus Nucleus of Darkschewitsch Nucleus of the posterior commissure

These nuclei are involved in vertical and rotatory gaze (physiology), and smooth pursuit. They receive afferents from the visual association area; they project efferents through the medial longitudinal fasciculus to the nuclei of cranial nerves controlling extrinsic eye muscles.
