Schematic of the brainstem auditory system of the barn owl. Auditory nerve (AN) fibers bifurcate to project to both cochlear nuclei, NA and NM. NM is the first nucleus belonging exclusively to the ITD processing pathway and projects to NL in which coincidence detection takes place. NL projects to the ICCc. NA projects to the LLDp; these nuclei comprise the ILD processing pathway. The ITD and ILD processing pathways converge on the ICCls, which projects to the external nucleus of the inferior colliculus (ICx).
