Eric Trautmann, a graduate student from the Shenoy Lab at Stanford University, entered this video in a contest to promote public literacy in science. It explains key concepts embodied in a scientific paper (http://engineering.stanford.edu/research-profile/stanford-researchers-reveal-more-about-how-our-brains-control-our-arms) co-authored by Stanford doctoral student Katherine Cora Ames — a mathematical analysis of the brain activity of monkeys as they make anticipated and unanticipated reaching motions. The video won an award from the National Science Foundation.
