Ian Burkhart, an Ohio man who was paralyzed four years ago during a driving accident, talks about a new technology that bypasses his injured spinal cord and translates his brain signals into movement. Plus, Dr. Ali Rezai, director of the neuroscience program at Ohio State University’s Wexner Medical Center, join us to discuss the technology that makes it possible. Then, in light of the controversy over Facebook’s user emotion experiment, we talk to Karen North, professor of social media and psychology at USC, about how social networks affect psychological conditions of people who use them. Last up, Tony Romm, a reporter at Politico, on how Google is lobbying at the state level to pave the way for its newest technologies.
