Medial geniculate nucleus
The medial geniculate nucleus (medial geniculate body) is a nucleus of the thalamus (the largest part of the diencephalon). As the central switching point of the auditory pathway, it transmits impulses from the inferior colliculus to the auditory radiation. Together with the lateral geniculate body, it forms the metathalamus.

Lateral geniculate nucleus
The lateral geniculate nucleus is the section of the thalamus (the largest part of the diencephalon) where around 90% of the optic nerve axons terminate. It has a characteristic stratification into six cell layers. The nerve cells of the lateral geniculate nucleus send their projections to the visual cortex. Together with the medial geniculate nucleus, it forms the metathalamus.

Primary auditory cortex
The first processing station in the cerebral cortex for auditory information. The primary auditory cortex is located in the Heschl's gyrus and receives inputs from the medial geniculate nucleus of the thalamus. It is organized tonotopically – its neurons are arranged continuously according to frequency.
