Not sure that works. Remember, a neuron is a relatively simple mechanism. It is just that a bunch of them together make one "smart" or whatever. So alcohol's wanton destruction of neurons is only destructive I would think, because there are not "stronger" vs. "weaker" neurons. They are all pretty much the same, simple mechanisms. The more the better, and so killing some of them off just can't be good, I don't think. I am not a doctor but I do know neurons are fairly simple. They fire if a "threshold" of electric potential is exceeded, else they don't. They are simple, stupid, binary mechanisms. But put lots of them together and you eventually get Einstein. So killing neurons can only be bad I think.
