Part of the thalamus. At least two pathways from the medial geniculate lead to several auditory cortical areas. 


Neurons are excited and inhibited by frequencies to help sharpen the frequency responce and allow for discrimination.

Medial geniculate nuclei

A key component of the auditory thalamus, the medial geniculate nucleus serves as a critical relay station in the auditory pathway. It receives auditory signals from the inferior colliculus and transmits them to the auditory cortex for higher-level processing.

Medial Geniculate Nucleus

This is where some information from the cochlear nuclei converge. The outputs go to the medial geniculate nuclei.

One of the cochlear nucleus pathways goes to the superior olivary nuclei. Both the right and left superior olivary nuclei recieve input from both the right and left cochlear nuclei, causing bilateral input. This allows for the central nervous system to localize sound by comparing the input for both ears.
