In our first Fish Fry podcast of 2021, we sit down with Dr. Scott Frey (University of Missouri) and chat about the challenges and newest advancements in brain-hand communication. We take a closer look at how Dr. Frey and his team are helping to personalize recovery from ‘lost’ limbs and the details of a new wireless device that could help people with severe upper limb injuries live better lives. Keeping with our brain-related theme this week, we also investigate a recent study from MIT that reveals that reading computer code is a brain beast of its own and does not precisely replicate the cognitive demands of language or math.
