Right. Because one guy who goes to GW knows more than a community of intellectuals (plus a few morons here and there).
I am studying medicine and I had a Neuroanatomy course last semester.
Now, what I'm saying is that even if this stuff works it's complete bullshit and most likely psychosomatic. It's never a good idea to tamper or attempt to tamper with your brain. If the damned thing was so simple, we'd already have good A.I.s.
In short... If anything, it might work because you are meditating and calming yourself... The whole amygdala shit is just pseudo-science to help and trigger that. Now, some stupid kid might (And most probably would) get the wrong idea and could try to stick a probe up his nose in order to "click" his actual brain.
Omcifer: If you really are interested in the human brain, you could study Medicine (Neurology), in the meantime... I suggest you take a hold of "John Martin's Neuroanatomy."
