"Neuroscientists at the University of New Mexico asked volunteers to play a video game called "DARWARS Ambush!", developed to help train American military personnel. Half of the players received 2 milliamps of electricity to the scalp, using a device powered by a simple 9-volt battery, and they played twice as well as those receiving a much tinier jolt. The DARPA-funded study suggests direct current applied to the brain could improve learning." -Gizmodo, PopSci
"Now it appears zapping your brain with a 9-volt battery will make you better at video games" -PopSci
