Cochlear Implants
... The implant converts the digitally-coded sound into electrical impulses and sends them along the electrode array placed in the cochlea (the inner ear). The implant's electrodes stimulate the cochlea's hearing nerve, which then sends the impulses to the brain where they are interpreted as sound. 1. T ...

... The COCHLEA is a snail-shell shaped, membrane-bound, fluid-filled receptor for sound of the inner ear. When viewed in cross-section , the cochlea is divided into upper and lower halves by the BASILAR MEMBRANE. Angling into the upper half is another membrane called the TECTORIAL MEMBRANE. Resting on ...

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.
