『Experiment lets man use his mind to control another person's movements』
So it turns out a bit of mind control might be possible after all. Scientists had already shown that a human could send an electronic brain signal to a rat, prompting it to wiggle its tail. Now, two University of Washington researchers say they have demonstrated that one person's thoughts can control another person's movements.
First, electrodes were placed against the subject's head. The first subject than looked at a computer game on a screen and thought about what move he wanted to make. The second subject, sitting on the other side of the campus but connected to the first subject via the Internet and a brain stimulation device, almost instantaneously moved his right index finger to make that move. He said it had the sensation of a nervous tic.
In the past two decades, neuroscientists have made dramatic advances in connecting human brains with computers, largely in the hope of helping disabled and paralyzed patients communicate with others and operate prosthetic limbs.
The previous brain-to-brain interfaces involved electrodes implanted directly into rat brains. "This is the first noninvasive brain-to brain interface," said Rajesh Rao, the computational neuroscientist whose brain sent the signal.
Neurobiologist Miguel Nicolelis at Duke University, who in February reported that he and his colleagues linked two rat brains together across continents, said this latest research is rudimentary at best. "This is more like one brain sending an electric shock to another than a true interface," Nicolelis said.
