The<unk>  is a tract of axons in the brainstem that carries information about sound from the cochlear nucleus to various brainstem nuclei and ultimately the contralateral inferior colliculus of the midbrain. Three distinct, primarily inhibitory, cellular groups are located interspersed within these fibers, and are thus named the nuclei of the<unk> .
Lateral lemniscus
Paramedian reticular nucleus
Medial pulvinar nucleus
Sublingual nucleus
Caudal pontine reticular nucleus
Reticulotegmental nucleus
Inferior colliculus
Ventral lateral nucleus
