Wow. Normally, just after an accident resulting in paraplegia / amputation, the brain's neurons are still able to adapt that now-useless part of the sensory map to a new sense. I seem to remember a case where a patient was able to map their right hand feelings to their prosthetic arm and hand (or similar), and also of weird stuff like a newly-blind person's pain receptors on their face giving off colours, or some such. (Sorry, the details are so sparse, it must be a ong time since I read this. Probably a lecture I fell asleep in ...)
