Inferior Colliculus

A primary auditory relay nucleus located in the midbrain, involved in processing auditory information, especially sound localization and frequency discrimination.

Key Functions:

• Processes auditory information (sound localization, frequency discrimination).
• Relays auditory signals to the medial geniculate nucleus of the thalamus.
• Involved in acoustic startle reflex.

Interacting Systems & Components:

• Midbrain (located in)
• Auditory Pathway (key relay station)
• Medial Geniculate Nucleus (projects to)
• Superior Colliculus (interacts with for sound-guided eye movements)
