Inferior colliculus
Two posterior elevations of the midbrain roof are referred to as the inferior colliculi. Together with the superior colliculi, they form the midbrain tectum. Impulses from various nuclei of the lower brain stem converge at the inferior colliculi. In addition, signals from the auditory cortex arrive here. This makes the inferior colliculi an important coordination center for auditory information.

Auditory pathway
The auditory pathway refers to the nerve fibers that transmit acoustic information from the inner ear to the primary auditory cortex. In humans, the auditory pathway consists of five switching points: the spiral ganglion, the auditory nuclei in the brainstem, the inferior colliculus, the medial geniculate body of the thalamus, and the primary auditory cortex.

Medial geniculate body
The medial geniculate body (medial geniculate nucleus) 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.
