Hi Dr. Hill,

I'm not sure how AMA's work - this is the first I have been in, but if you are still here;

Could you shed some light on the biological pathway of 'how' a nootropic like, say, the thinkdrink or Piracetam (or whatever you are most comfortable explaining) works? Are things like withdrawal or tolerance a potential issue?

Second, what are your thoughts on the use of neural stimulation from something like a TMS to achieve nootropic effects?
