Auditory Brainstem Implants stimulates the cognitive brain

Yvonne Foong on the Auditory Brainstem Implant:

"I did not actually hear any better. Her voice still sounded robotic through my Auditory Brainstem Implant. But somehow the second time around, her more relaxed and slower speech enabled a part of me to perceive the words cognitively similar to the effects of healthy sound perception but without hearing them accurately.

i used to think each channel of the multichannel electrode array of the Auditory Brainstem Implant represents a different pitch, like how we would tune string instruments. But each time Steve Otto tested the threshold with each of mine, all activated channels sounded at almost the same pitch. Although I was able to sort them out as a scale, from lowest to the highest, but they weren’t much different from each other. Only until lately did I understand that the purpose of having multiple channels was to make sure that if some causes side effects when activated, there are still others to try and use. Each channel may stimulate a different part and cause us to hear an extra pitch, but the electrodes themselves do not make pitches."
