A cochlear implant is a small electronic medical device that improves moderate to severe hearing loss. It’s used to help hearing loss in adults, children, and babies. The device works by electrically stimulating the cochlear nerve
Cochlear nerve
The cochlear nerve is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain. The other portion of the vestibulocochlear nerve is the vestibular nerve, which carries spatial orientation information to the brain from the semicircular can…
