Bipolar Ganglion cells of the auditory nerve-

Peripheral projection as multiple single fibers innervating only one inner hair cell. Others project to multiple outer row hair receptor cells.
Central projection to brainstem complex in the pons/medulla brainstem.

Bilateral cochlear complexes of brainstem consist of dorsal and ventral cochlear nuclei.
Crossed connects of axons from these paired nuclei project to same side and contralateral MNTB (medial nucleus of the trapezoid nucleus).
MNTB form lateral lemniscus; These nuclei serve Inhibition for targeting directional auditory sensitivity.
Superior olive- Efferent source to outer row HC’s
Inferior Colliculus- Processes directionality, Tone specifying reflex; Tectospinal alerting reflex; Ascending connection is to the MGB.
Medial Geniculate Body- Temporal station unifying cortical inputs by synchrony.
Primary Auditory Cortex- Sound understanding and appreciation.
