Want To Up Those Maths Results? Try Electricity

If you're not among the mathematically gifted, there's hope for you yet - and it doesn't involve any studying. Instead, researchers have found that a little electric stimulation may add up to better maths skills.

Participants in the study were given a one milliamp electrical stimulus across the parietal lobe for 20 minutes a day. It doesn't amount to more than a tingle, according to Oxford University's Cohen Kadosh, but the student volunteers who underwent the treatment found their performance level significantly improved on a battery of tests. Not only that, but the boost still held six months after the initial jolting.

Two quick thoughts. First, please don't try to self-electroshock your way through differential equations. Second, would this process be more or less expensive than a kickass graphing calculator? [Reuters]
