Neuroscientists are racing to perfect brain-computer interfaces and as they do, the line between sci-fi and reality blurs. Iron Man exoskeletons, Matrix-style brain downloads and Vulcan mind-melds feel within reach.

“I think nothing is impossible up front,” said Deniz Erdogmus, an associate professor of electrical and computer engineering at Northeastern University specializing in noninvasive brain-computer interfaces or BCI for short. He and his colleagues are developing a brain-controlled keyboard to help people with speech impairments communicate rapidly.

While we’re not at Spock level yet, Erdogmus shares some of the most promising brain-controlled tech out there.
