Hair cells transduce mechanical information into electrical signal and, via afferent synapse, transmit it to the central nervous system (CNS). Hair cells receive cholinergic efferent innervation from the CNS, and a long-lasting membrane hyperpolarization is produced by activation of Ca2+-activated K+ channels. Acetylcholine may facilitate afferent synaptic transmission by suppressing K+ channels on the afferent nerve terminal.
