Summary
The medial geniculate nucleus, or MGN for short, is a nucleus located in the thalamus of the brain. This nucleus receives auditory information from the inferior colliculus and superior olive of the brainstem, before transmitting it forward to the primary auditory cortex for further processing. In this way, the MGN acts as the primary thalamic relay for hearing in our brain.
