The superior olivary nucleus consists of the lateral superior olive and medial superior olive, as well as a number of surrounding nuclei known as the periolivary nuclei. The superior olivary nuclei are thought to be involved in hearing, and specifically with identifying the location of sounds.

What is in the superior olivary nucleus?
The superior olivary nucleus consists of the lateral superior olive and medial superior olive, as well as a number of surrounding nuclei known as the periolivary nuclei. The superior olivary nuclei are thought to be involved in hearing, and specifically with identifying the location of sounds.
What is the function of superior olivary nucleus?
The superior olivary complex (SOC) is a group of auditory nuclei in the brainstem of amphibians, reptiles, and mammals. One major function of the SOC is to encode the cues that contribute to sound lateralization on the basis of convergent binaural ascending inputs arising from both ventral cochlear nuclei.
Where is the superior olivary complex found?
pons
Gross anatomy. The superior olivary nuclei are located in the pons, while the inferior olivary nuclei are located in the medulla. It is generally situated caudally near the facial nucleus, in the tegmentum of the caudal pons.
Is the superior olive a nucleus?
The superior olivary complex (SOC) or superior olive is a collection of brainstem nuclei that functions in multiple aspects of hearing and is an important component of the ascending and descending auditory pathways of the auditory system.
Where is the inferior olivary nucleus found?
superior medulla
The inferior olive nuclei are in the superior medulla, just inferior to the pons. Their composition is the grey matter in the shape of crenated “C,” in which the hilum is medially directed. The hilum faces the opposite inferior cerebellar peduncle (ICP), and a large number of fibers travel to and from it.
What is the afferent synapse of the superior olivary complex?
The output of the superior olive travels in the lateral lemniscus. Some nuclei within the lateral lemniscus further process the sound. Most of these afferents synapse in the inferior colliculus. All afferents then synapse in the medial geniculate body of the thalamus.
What is the inferior olivary nuclei?
The inferior olivary nucleus (ION), is a structure found in the medulla oblongata underneath the superior olivary nucleus. In vertebrates, the ION is known to coordinate signals from the spinal cord to the cerebellum to regulate motor coordination and learning.
Where is the cochlear nucleus located?
brain stem
The cochlear nuclei (CN) in man consist of the dorsal (DCN), superior ventral (SVCN), and inferior ventral (IVCN). The CN is located on the dorsolateral surface of the brain stem at the junction of the medulla with the pons.
