Today’s guest is John Donoghue. He is well known for his groundbreaking work developing Brain Computer Interfaces (BCIs) to restore movement for people with paralysis, known as ‘BrainGate’. BrainGate was the original BCI system created by a company called Cyberkinetics, of which John was a co-founder. In this episode, John gives us a primer on BCIs.  What are they? How do they work? When will they be widely adopted?  Are they safe?  How do we know?  We cover these questions and much more.
