The technique called transcranial direct current stimulation (tDCS), uses a simple circuit driven by a 9 Volt battery to provide electrical stimulation directly to the brain. This can improve everything from visual perception and memory to motor control, depending on where the electrodes are placed on the skull.
In a study funded by DARPA, volunteers were asked to play a game called DARWARS Ambush! created to help train soldiers. It was found that those playing with a 2 mA buzz running through their heads played about twice as well as a control group who only got a tiny amount of the juice.
(Oh, no, I can see it coming; the latest dangerous thing to do, kids frying their brains trying this.)
