The motion of the hair cells allows electrical potentials to travel to the auditory nerve and become processed by the brain. Hair cells are theorized to be frequency-selective: specific pitches excite specific areas of t ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
