Neurostimulation - The Genius Machine?

Do you wish you were smarter? Are you often baffled by puzzles? According to Australian neuroscientists Chi and Snyder, all you need is a bit of electric assistance: Brain stimulation enables the solution of an inherently difficult problem. In their study, 22 volunteers were faced with the 9 dots problem, a notoriously difficult puzzle. The goal here is to draw exactly four straight lines connecting all nine of these dots, without retracing any line, or lifting your pen from the page.
