This week, we're taking a look at the brain and a world-changing idea that could overhaul how we approach brain surgery.

A company called Synchron is investigating how you restore, treat, and map the electrical activities of the human brain. And they’ve developed the first brain-computer-interface implant in the United States. It’s called a Stentrode, and when the device gets implanted, it can allow severely paralyzed patients to control personal devices without using their hands.

Producer Avery Miles sat down with Peter Yoo, Synchron’s director of Neuroscience, at last year’s Fast Company Innovation Festival to learn more about how this technology works.
