Ehhhh thinking its dubious.
It's not making a lot of sense to. They're talking about regrowing parts of the auditory nerve. The auditory nerve, not the hair cells, so I'm not sure why would this would help. The auditory nerve send the signal to your brain, you don't actually hear with it. It's the hair cells being damaged that typically cause sensorineural loss. You have to have a healthy auditory nerve to even receive a CI so why would it need any regrowing?I also don't understand how that would improve pitch differentiation because again....that's from the hair cells, but in the case of an implant it's dependent on the electrodes. Btw C-Nice Advanced Bionics can give better pitch differentiation than the other brands, although med-El is probably close.
But meh, I'm not a scientist, but it's not making sense to me unless we're talking about someone that has a problem with their auditory nerve. This would maybe help with someone that has had severe to profound loss their whole life. I can see something like this helping them since auditory nerve might have some atrophy from little use.
It's Parkinson's though, Alzheimer's isn't a nerve thing.
