Peripheral nerves regrow but slowly. It can take a very long time for them to grow the length of a limb so things are sort-of reconnected, which is why rehab takes so long.
They can only reconnect it if it is not missing or too damge.If it is too damage or missing they cannot reconnect it and you will lose that harm ,finger ,foot or leg or what ever it is.
Previously it was thought that central nervous system tissue (brain, spinal cord etc.) didn't grow back, but this is no longer the case.
I think what the body can do some times is by pass the damge nerves .It like you have 3 roads going from your home to your work now that say one road you cannot go on so you can take the other road to work.
Much work is now going into bridging damaged spinal cords and brain tissue, and the results are very promising especially as concerns spinal cord injuries.
I'm not sure I understand this. Are you saying they came up with a drug to regrow it?
One development is the use of antibodies to negate the action of NOGO, a family of molecules that prevent nerve fiber regrowth. Also interesting is that olfactory glia cells, normally involved in smell and not present in the cord, can be used at the injury site to promote regeneration of cord nerve fibers.
Not sure what glia cells are or how antibodies wil be used to regrow nerves
