Well, the ends of the nerves have reaction to the other nerve endings, as
opposed to anywhere along the nerve, generally. So, like a coaxial cable, you
could put a new dendrite on the end of a nerve, or put a connecting dendrite
that just forwarded messages to the original length and input of the nerve.
Then there is a biological layer where the nerve endings have chemical
reactions. That is a very small scale. Then, the system has to emulate the
old nervous reactions, because the old nerve will keep sending some of the same
messages as before the limb was amputated.

Brain function happens on a very small scale and in very complex ways. Anders
has nice pictures of the brain on his web page.
