After an interminably long wait, the first brain-boosting tDCS headset has finally received FCC approval and will begin shipping in the next few days. Dubbed the Foc.us, the headset jolts your prefrontal cortex with electricity, improving your focus, reaction time, and ability to learn new skills. The Foc.us is being targeted at gamers looking to improve their skillz, but tDCS has the potential to improve -- or more accurately to overclock -- almost every aspect of your life.
