a device that sends signals - this is the amazing part - to implants that are DIRECTLY placed on the brain stem. The device allows
"Many children (that are) born deaf benefit from cochlear implants, electrodes that send impulses to the auditory nerve, where they're relayed to the brain and recognized as sound. But the small fraction born without a working hearing nerve can't make that brain connection.
The ABI (Auditory Brainstem Implant) attempts to fill that gap by delivering electrical stimulation directly to the neurons on the brainstem the nerve normally would have targeted. Here's how it works: The person wears a microphone on the ear to detect sound, and a processer changes it to electrical signals. Those are beamed to a stimulator under the skin, which sends the signals snaking through a wire to electrodes surgically placed on the brainstem."
