@granny73 here is a good start for an explanation on brain neuroplasticity
-- Neuroplasticity 101: https://www.brainfutures.org/neuroplasticity-101/

A couple of books that I started reading were by Norman Doidge, M.D., The Brain's Way of Healing and The Brain that Changes Itself, are described on his website here https://normandoidge.com/. I read most of the first one and a little of the second one as my feeble brain didn't comprehend what I was reading. 🙃 It's definitely interesting and if you want to search YouTube, there are a lot of videos that may be easier to learn from if you search using "brain neuroplasticity and neuropathy".
