BrainGames

There is a product developed by NASA that that they use as a training aid to their pilots. It's basically a Neurofeedback device; meaning, it sorta displays brain waves. EEG Neurofeedback training uses a computer assisted EEG (Electroencephalogram) which accurately measures Brainwave activity through sensors, safely placed on the surface of the head. This brainwave activity can then be monitored visually and auditorally.
Through this sophisticated feedback system, individuals are taught to effectively exercise their brain, leading to increased awareness and differentiation of mental states.
Researchers are trying to team this product up with video games which will give it a more appealing front. It is geared especially towards helping kids with ADHD. Here's a video that gives a bit more detail.

It will probably still be a few years till this gadget is something kids would feel comfortable or "cool" with. I say that simply because it's not really known and recognized yet by mainstream America and it's really kinda dorky looking having all that equipment on your head and all. I think it's something we should keep a close eye on though. We could develop little labs with these hardware available to help kids develop their brain. (Sorry if that last line sounded a bit creepy)

Pitfalls: It's kinda expensive right now so that's not such a great thing. It's really dorky looking as I said above so kids might not be ready and willing to get into it. Also I don't really have much information on the setting up and putting together of the equipment so I don't know how hard that'll be.
