The idea of controlling objects — even other humans — with only your brain is a Holy Grail of tech innovation. And what researchers did at the University of Washington this month sounds pretty amazing. Using non-invasive technology to record and stimulate brain function, a researcher at one end of campus controlled the physical actions of someone at the other end of campus. Researcher Rajesh Rao was the mind controller in this experiment, and tells Marketplace Tech host Ben Johnson how he did it and what his findings means for the future.

Below, watch a video of the experiment.
