Medial geniculate body

Last revised by Dr Elmira Hassanzadeh on 12 Jun 2021

The medial geniculate body, also known as the medial geniculate nucleus, is one of the thalamic nuclei. It acts as the principal relay nucleus for the auditory system between the inferior colliculus and auditory cortex.

Together with the lateral geniculate body, it forms the metathalamus.
