Big Picture on BMI

This week's Big Picture Science examines brain-machine interfaces (BMIs). Guests include engineer of the tiny Jan Rabaey, at the Center for Neural Engineering and Prostheses, who is developing wireless micro-electrode grids that can send signals out of human brains;  Human Connectome researcher Arthur Toga,  a UCLA cartographer of human brain function; UCSF neuroscientist Brad Voytek, who studies attention and memory in ECoG-implanted epilepsy patients; and senior UCSC neurobiologist Michael Gazzaniga, author of the recent book Who's In Charge?: Free Will and the Brain. The interviews are excellent, and the show opens up with my 13-year-old son Leo and me playing Mind Flex, an EEG-based game that we got for Christmas.
