Cochlear Implant

Illustration of a cochlear implant in the ear, showing how sound travels to the brain. The transmitter is worn behind the ear (shown here next to the ear), linked to a transmitting antenna placed under the scalp, which transmits sound to a receiver placed under the skin, to the electrode array rolled up in the inner ear duct (in the cochlea). Sound is transmitted to the auditory nerve and to the brain.
