The ability to grow brain and spinal cord nerve cells is present at birth- and starts to disappear just like that as we age. So, when we incur an injury to the spine or the brain- the axons (as discussed earlier) can’t regenerate. It is thought that since these areas are replete with nerves and nerve fibers, they send signals to stop new connections from forming. By stopping new pathways from forming, our brain can’t be confused with by incorrect signals that could result from the new pathways.
