The superior olivary complex (SOC) or superior olive is a collection of brainstem nuclei that is located in pons, functions in multiple aspects of hearing and is an important component of the ascending and descending auditory pathways of the auditory system.
Diagram of a cross-section taken horizontally through the lower part of the pons of a human brainstem and stained with the Kluver-Barrera method. Due to the staining method, white matter (axons) appears blue and gray matter (cell bodies) appears light gray. Notes: Anterior is down, posterior is up.
The inferior cerebellar peduncle is formed by fibers of the restiform body that join with fibers from the much smaller juxtarestiform body. [1] The inferior cerebellar peduncle is the smallest of the three cerebellar peduncles.
The olivocochlear system is a component of the auditory system involved with the descending control of the cochlea.Its nerve fibres, the olivocochlear bundle (OCB), form part of the vestibulocochlear nerve (VIIIth cranial nerve, also known as the auditory-vestibular nerve), and project from the superior olivary complex in the brainstem to the cochlea.

The olive consists of two parts: The inferior olivary nucleus (or 'complex'), which is a part of the olivo-cerebellar system and is mainly involved in cerebellar motor-learning and function. The superior olivary nucleus, considered part of the pons and part of the auditory system, aiding the perception of sound.

The medial vestibular nucleus (Schwalbe nucleus) is one of the vestibular nuclei. It is located in the medulla oblongata . Lateral vestibulo-spinal tract (lateral vestibular nucleus “Deiters”)- via ventrolateral medulla and spinal cord to ventral funiculus (lumbo-sacral segments). ..
