I wonder when the first real such product will exist. Like any system that synchronizes by waves it can be modified by waves, probably much more than you'd be able to do through chemicals.
So who will make the first heroine headband ? It will probably need outputs as well as inputs though.
It seems to just be a biofeedback device. It tells you when you are experiencing the right brain wave pattern so that you're consciously aware of it, but you have to do the work of meditating to alter the state.
