The telepathic cyborg lives, sort of. University of Washington scientists Rajesh Rao and Andrea Stocco claim that they are the first to demonstrate human brain-to-brain communication. Rao sent a signal into a Stocco's brain via the Internet that caused him to move his right hand. Brain-to-brain communication has previously been demonstrated between rats and from humans to rats.

"The experiment is a proof in concept. We have tech to reverse engineer the brain signal and transmit it from one brain to another via computer," said Chantel Prat, an assistant professor of psychology who worked on the project.
