More to the point, could they enhance your gaming awesomeness?
(august 2014) Oh great: Cool, clever marketers are using data about transcranial direct current stimulation (TDCS) -- which passes small
electrical currents directly onto the scalp and theoretically stimulates the nerve cells
in the brain -- to entice gamers, and whomever else they can think of, to buy their cute, futuristic-looking gadgets ((http://www.bbc.com/news/health-27343047).
Since they are not making medical
claims (in their opinion, anyway), the are not subject to regulatory
oversight. One of their ads exclaims: "Can you learn 20-40 percent quicker, reduce pain, feel better, increase
energy or reduce stress with tDCS? Research studies say, YES!" (Don't these sound like medical claims to you?) Studies also indicate you could mess up your precious, incredibly complex and beautiful minds, you fools!
