The inner ear includes the cochlea , the hearing organ, and the semicircular canals and otolith organs, the sense organs of balance.
In the cochlea in the inner ear, the vibrations are changed into electric signals that move along the nerves to the brain.
This measures the responses the cochlea makes to sounds produced by a probe placed in the outer ear.
By completely bypassing the damaged part of the cochlea , the cochlear implant uses its own electrical signals to stimulate the auditory nerve, allowing the person to hear.
