A new study shows that often people flub a movement or do something spastic due to "spontaneous brain activity." These random electrical bursts in the brain can't be explained, but they might help account for why certain people are always dropping dishes or tripping on their own feet. Can't wait for EEG hackers to figure out how to induce freaky physical twitches by zapping their brains. Hey, spasms could be a fetish of the future!
