A member asked:
Most neurons in the brain and spinal cord are not regenerated, right?
A doctor has provided 1 answer
Not quite correct: For years, it was felt that nerve cells would not heal. If the cell body dies (apoptosis), it does not resurrect. If the nerve fibre axon is transected, it will not reconnect. But the myelin covering can regenerate, and the brain can employ alternative pathway connections with time.
