Rewiring?

It was interesting to read that surgeons in Australia have managed to restore a good degree of hand function in around half of their quadriplegic patients by moving surviving nerves in the arm so that they take on the functions of the nerves that formerly provided the connection to the spinal cord (https://www.bbc.co.uk/news/health-48868670). This has enabled some of the patients to gain sufficient arm control as to regain a relatively independent life style and even to play sports. This is, of course, only possible in patients with a combination of features but it does appear to be transformative in those cases.
