Amol Sarva expounds on the next frontier in the exploration of consciousness: neurostimulation (via Wired UK):
The idea of stimulating brain performance seemed very plausible when I first heard about it, taking my PhD in cognitive science at Stanford. Your brain operates with electricity; why couldn’t electric current or waves boost it a bit? Gentlemen physicists such as Volta and Galvani were fiddling with frogs’ legs and cadavers back around the late 18th century. Another Italian wrote about curing melancholia with electricity in 1804. And today, everyone knows about the power of shock therapy.
But what appeared on my radar in 2003 was different: a headset that sent weak electromagnetic waves into your head. Lawrence Osborne, in The New York Times Magazine, reported that after his brain was electrically stimulated, he suddenly produced some incredible cat drawings. Admittedly, this was no peer-reviewed journal: in fact, no lab had been able to reproduce the findings of the man behind this and similar experiments, a University of Sydney physicist named Allan Snyder.
