Well, there are also methods of injecting stem cell cultures into the brain to
stimulate new young brain growth. I imagine that these therapies could be used
to help maintain brain plasticity, however a significant problem with the brain
is hardening of arteries, capillaries and veins over time, esp with people with
long term exposure to smoke and pollution, and I seem to recall that high doses
of vitamin C also cause some hardening effects...
