Diy brain enhancement
Zapping your brain with a small current seems to improve everything from mathematical skills to marksmanship, but for now your best chance of experiencing this boost is to sign up for a lab experiment. Machines that provide transcranial direct current stimulation (tDCS) cost £5000 a pop, and their makers often sell them only to researchers.
That hasn't stopped a vibrant community of DIY tDCS enthusiasts from springing up. Their online forums are full of accounts of their home-made experiments, including hair-curling descriptions of blunders that, in one case, left someone temporarily blind.
What drives people to take such risks? Roy Hamilton, a neuroscientist at the University of Pennsylvania in Philadelphia, thinks it is part of a general trend he calls cosmetic neuroscience, in which people try to tailor their brains to the demands of an increasingly fast-paced world. "In a society where both students and their professors take stimulant medications to meet their academic expectations," he warns, "the potential pressure for the use of cognitive enhancing technologies of all types is very real".
