Definition: axons that arise from neurons in the cerebellar nuclei, exit through the superior cerebellar peduncle, cross in its decussation, and descend in association with the central tegmental tract. Depending on their origin, these fibers terminate in the accessory and principal olivary nuclei: the anterior and posterior interposed nuclei to the dorsal accessory and medial accessory olivary nuclei respectively, the medial cerebellar nucleus to the medial accessory olivary nucleus, and the lateral cerebellar nucleus to the principal olivary nucleus.
