A researcher made a colleague's hand move from across the campus of the University of Washington using brain signals sent over the Internet. Rajesh Rao, computer science and engineering professor at the university, had electrodes on his head, which were connected to a machine to read the electrical activity, and played a simple computer game only with his mind. The signal was received by a researcher across campus who was wearing a transcranial magnetic stimulation coil on his left motor cortex. The researcher said the feeling of his right hand moving was like a nervous twitch.
