Cochlear nerve

The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. The function of cochlear nerve is mostly gathering of auditory data from the environment and transmitting it to the brain for processing. It is one of the many pieces that make up the auditory system, which enables effective hearing. The function of cochlear nerve begins when the sound vibrations hit the ear drum (tympanic membrane). By hitting the ear drum, those vibrations are converted into an electrical signal that cochlear nerve carries to the brain. The cochlear nerve can be affected with many different disorders and diseases. These diseases can damage the nerves in the auditory system, causing the loss of hearing. The hearing loss usually includes treatment with the usage of hearing aids in the form of cochlear implants. The cochlear implants represent very effective treatment because they usually manage to restore a significant proportion of lost hearing capability.
