“Imagine a person who is confined to a wheelchair but can still get around through nothing less than the power of thought. Neuroscientists have experimented with brain waves for years, making slow progress. Now Dr. Bin He of the University of Minnesota and his team report a promising experiment.
They outfitted volunteers with caps with EEG sensors, and asked them to steer a helicopter on a computer screen through a series of randomly generated rings that appeared on the screen ahead of it. There were no hand controls, no joysticks. They could only try to will the helicopter forward with their minds.”
