How can someone regenerate his/her brain?


Question:
It is a well-known fact that "extacy" users damage and eventually lose their serotonin neurons. Those neurons that do not die, are still severely damaged and lose their axons, and thus their ability to communicate with neurons downstream. There must be a way to promote axon growth in those neurons which are not dead, but are simply "de-axonized".
One possible method is to take Inosine, a supplement that is readily available at any vitamin shop. Inosine has recently been shown to regenerate axons in damaged spinal cord neurons in mice (in vivo!), when administered parenterally. Of course this is a long way from human brain neurons (administered orally), but there is still a chance that this may prove to be somewhat effective.
Does anyone know of, or can anyone suggest another possible method? Any feedback will be greatly appreciated. Thank you.

Answers:
Well, our professor was telling us about the possibility of applying stem cell technology in this area. Embryonic stem cells when given the right environmental cues can develop into neurons. Alternatively, Schwann cells which are the ones that wrap around the axons and allow for conduction can also be generated from embryonic stem cells. Hope that helps.

Other Answers:
Brain cells that die don't grow back. If you screw up, to bad.
Unless stem cell research finds a cure sometime.
