inferior colliculus
Brainstem hearing relay
The inferior colliculus is a structure in the midbrain that serves as a major relay station for auditory information.
Sound signals from the ears pass through it on their way to higher brain regions for processing.
The plural is inferior colliculi: Damage to the inferior colliculi can impair sound localization.
