The historic view is that once brain cells are damaged or killed, they do not regenerate. Yet, research over the last 20 years is showing substantial evidence of cell regeneration, particularly in those under 40 year of age.
However, the best therapy should be able to also repair damage. The spinal cord (and the brain) is well known for its inability to self-heal. However, the right environment can induce axons of the spinal cord to regenerate. But it is precisely in this environment that lies the main problem, since the spinal cord contains a myriad of molecules that actively inhibit axonal regeneration.
