- the spiral cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations
In man, the cochlea and the organ of Corti follow a spiral course of two and one half turns.
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.
This measures the responses the cochlea makes to sounds produced by a probe placed in the outer ear.

In the cochlea in the inner ear, the vibrations are changed into electric signals that move along the nerves to the brain.
When a hearing aid does not give sufficient amplification, as with profound deafness, a cochlear implant may help.
Sensorineural hearing loss indicates a disease or abnormality of the inner ear or cochlear portion of the eighth cranial nerve.
The presence of tinnitus often heralds a cochlear hearing loss.
A device called a cochlear implant can be surgically inserted in the inner ear of children as young as 12 months of age to stimulate hearing.
No significant cochlear impairment was noticed in metabolically well-controlled diabetic patients in comparison to controls.
