Yeah tDCS seems interesting. Amazing! <br><br>All you need is a 9V battery. Sweet. <br><a href="http://brainstimulant.blogspot.com/2008/06/tdcs.html" target="_blank">http://brainstimulant.blogspot.com/2008/06/tdcs.html</a><br>

<br>Also, they can apparently use pulsed ultrasound for noninvasive localized brain stimulation(from another another list). <br>
