Electricity to help gamers?

Ever wanted a way to improve your concentration so that you can gain that perfect headshot, or shooting the shotgun at the exact second to blow them to pieces? Well researchers at the university of New Mexico have been hard at work trying to find a way.
Running electricity through the scalp can improve concentration and reactions not just in gaming, it can also make you see funny lights and burning sensations. The volunteers were wired up to a 9 volt battery and had 2 miliamps powered into wet sponges attached to their right temple. The experiment was conducted on a game called Darwars ambush (designed for the US military)with little or no exposure to the game the volunteers showed signs of improvement.
The technique, called "transcranial direct-current stimulation" (tDCS), has been studied since the 1800s as a way to treat neurological conditions, suprisingly it has been making a come back in academic terms. With signs of improved word association and memory it could have some potential.
With no surprise i advise strongly against trying this at home, that sweet headshot can be achieved with practice.
