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.
