This researcher wants to replace your brain, little by little. The US government just hired a researcher who thinks we can beat aging with fresh cloned bodies and brain updates. (www.technologyreview.com)

go look at images of old telephone wiring like when POTS was still the main method.multiply those rats nests of wires by a billion and shrink that them down to the molecular size and you might see the issue

I cut a big nerve in my thumb years ago, and apparently plastic surgeons fix that sort of thing.

They reattached the nerve bundles, but I was told the sheathes could be realigned, but the nerves would have to grow back from the point of the cut all the way to the skin.

At first one half of my thumb was entirely numb, and over the course of well over a decade I'd get pins & needles as bunches of nerves would finish regrowing, except attached to random channels in the nerve bundle, so my brain had to completely remap all those signals to what they actually meant. Also extreme nerve pain near the cut whenever it was bumped, I assume because many nerves just didn't grow successfully and remained near that site.

It felt super weird because hot, cold, pain & touch were all mixed up, but eventually my brain sorted them out. It still feels a little weird, especially near my nail, but I haven't had a pins & needles experience for a few years.

The problem with doing that with a neck is that it would take wayyy longer and the chances of the patient dying from complications due to no brain signals working right... yeah I don't see medical science fixing this unless we can regrow nerves in a much shorter span of time.

Wow, that's fascinating. Thanks for sharing your story.

Thanks! As far as I know I'm not describing anything too unusual with the mixed-up signals, I think pins & needles is essentially that, just a bunch of nerves randomly firing, so you probably do know what it's like in little doses.

I've been paying attention to it since I wrote that, and it definitely is still slightly more numb on the affected side, I think I was right that not all the nerves regrew completely.

Just enhance a few times and it will be easy!
