Startups pioneering invasive and noninvasive devices that interact with the brain seek to alleviate everything from ALS symptoms to epilepsy to treatment-resistant depression. In this episode, a look at the science behind this rapidly advancing technology.

Dr. Thomas Oxley, a neurointerventionist and CEO of Synchron, gives us a tour of his lab in Brooklyn, New York, where his company is developing an implant that allows paralyzed people to control devices. 

Then Bloomberg reporter Sarah McBride joins Wes for a look at other startups making these brain-computer interfaces–and where the industry goes from here.
