When a person has a brain or spinal cord injury, nerve cells called neurons
often survive, but axons, the long connections
between neurons, are clipped, according to Dr. Stephen M. Strittmatter, of
Yale University School of Medicine in New Haven,
Connecticut. Unlike axons in other parts of the body, those in the brain
and spinal cord -- the central nervous system -- do not
regenerate after they have been damaged, he explained.


This goes against everything I have ever been taught about the nervous system.
It is the neuron that can not regenerate, not the axon. Could I have been
wrong all this time? (If so, it would not be the first time!)
