![]() ![]() ![]() Every time he did this, with near-instantaneous speed, a computer converted Rao’s brain signals into a digital signal and beamed it to Stocco’s TMS helmet. Rao, wearing an EEG helmet, was at the controls – but instead of using his hand to hit the spacebar to fire, he simply imagined moving his hand. The experiment went like this: Rao and Stocco sat across campus from one another, watching the same video game. By strapping one person into a non-invasive EEG helmet, and strapping the second into a transcranial magnetic stimulation (TMS) helmet, the researchers mind-melded themselves – for the sake of science. Succeeded in making one leap everyone was waiting for: A human-to-human brain-to-brain interface. Finally, in August 2013, University of Washington scientists Rajesh Rao In the summer of 2013, a team of Harvard University researchers engineeredĪ brain-to-brain interface between a rat and a human, enabling the human to control the rat’s tail movements simply by willing them to happen. Lead researcher Miguel Nicolelis, is “a new central nervous system made of two brains.” That advance happened in 2012, and other labs were quick to one-up Nicolelis and his team. Of rat #1 – despite the fact that the two were separated by thousands of miles. Its movement impulse came not from its own brain, but directly from the brain But rat #2 had never been trained to press the lever. An implant in the rat’s brain converted its neural activity into an electronic signal and beamed the impulse to the brain of the second rat, which leaped forward and pressed a lever in its own cage. ![]() The first rat pressed a lever, anticipating the tasty reward it’d been trained to expect. ![]()
