1. The inferior colliculus has a relatively high metabolism in the brain. 2. Sound location data thus becomes fully integrated by the inferior colliculus . 3. Fibers leaving these brainstem nuclei ascending to the inferior colliculus rejoin the lateral lemniscus. 4. The LSO projects bilaterally to the central nucleus of the inferior colliculus ( ICC ). 5. These small arteries supply portions of the midbrain, especially the superior colliculus, inferior colliculus , and tectum. 6. The trochlear nerve comes out of the posterior surface of the midbrain, below the inferior colliculus . 7. This indicates that the inferior colliculus is metabolically more active than many other parts of the brain. 8. The inferior colliculus receives input from both the ipsilateral and contralateral cochlear nucleus and respectively the corresponding ears. 9. The time and sound-pressure pathways converge at the lateral shell of the central nucleus of the inferior colliculus . 10. They reflect neuronal activity in the auditory nerve, cochlear nucleus, superior olive, and inferior colliculus of the brainstem.
