can nerves regenerate after being severely damaged
Nerves regenerate at the rate of one inch per month. Although sensation can be regained even after long periods of denervation (loss of nerve supply), muscle reinnervation will not occur after long periods of time without nerve innervation (nerve supply).
This is most unfortunate, as a capacity for successful nerve regeneration is a necessity for restoration of function following damage, through accident or disease, to the human brain and spinal cord. Success of optic nerve regeneration might also open the door to future strategies of eye transplantation.cientists around the world are working hard to find a way to regrow the optic nerve. In addition, because of its easy access, the optic nerve has long served as a standard model for the study of spinal cord injury and regeneration in lab animals.
