What it is
A cochlear implant is a device that is surgically implanted in the brain to help the user hear. The device runs through the cochlea in the ear and sends electronic messages to the brain when sound is detected.
A cochlear implant contains a microphone, a processor, a headpiece, an implant, and an electronic array.
Those who are a part of the Deaf culture believe that hearing loss is not a deficit that needs to be fixed, but is a part of the person who makes them who they are. There is also debate over using cochlear implants in children because it is such an invasive procedure. Some people think that it is wrong to implant a child who cannot make the decision for his/her self.
