Controlling a toy robot with your mind. Brain researcher, Nick Ramsey, of the UMC Utrecht, has managed to get study subjects to do just that. It forms the basis of a brain-computer interface that will allow paralyzed people to control a computer.
In the study, subjects had to lie still in a powerful, 7T MRI scanner, while the computer screen showed them what a toy robot's camera could ‘see'. The subjects did not move, but had to keep their eyes focused on a single point.
