Before revision: Mechanism Binaural hearingAction potentialsoriginate in the hair cells of the cochlea and propagate to the brainstem; both the timing of these action potentials and their rate provide information to the SOC about the orientation of sound in space Auditory nerve and cochlear nucleusThe key mechanisms of the AN and CN are fast synapses that preserve the detail timings, or temporal fine structure, of sounds as transduced to action potentials, from the hair cellss in the cochlea through to the olivary complex.
