Major afferent connections to the inferior colliculus nucleus. Afferent axons from the medial geniculate, contralateral inferior colliculus, lateral lemniscus, cerebellar cortex and primary auditory cortex connect to the inferior colliculus nuclei. Efferent connections include the medial geniculate body, contralateral inferior colliculus, superior colliculus, lateral lemniscus, and cerebellum (Figure 2).
