**Core Concept**
Cochlear implants are neuroprosthetic devices designed to bypass damaged or non-functioning parts of the ear and directly stimulate the auditory nerve, allowing individuals with severe to profound sensorineural hearing loss to perceive sound.

**Why the Correct Answer is Right**
Cochlear implants utilize an external sound processor that converts sound into electrical signals, which are then transmitted to an internal receiver and stimulator. The stimulator converts these electrical signals into electrical impulses that directly stimulate the auditory nerve. This bypasses the damaged or non-functioning hair cells in the cochlea, allowing the individual to perceive sound. The auditory nerve then sends these signals to the brain, where they are interpreted as sound.
