Computational theories have had a growing impact on the field of motor control. The goal of this annual symposium is to highlight advances in experimental and computational approaches to the study of motor control. The idea is to not only present interesting empirical observations, but also ask what these observations might imply in terms of how the brain controls our actions. A second goal is to provide an annual forum to hear some of the best and most interesting new experimental results on motor control, presented by people most directly responsible for it.
This year we had 44 extended abstracts. Each was ranked by 3 reviewers. The top 10 were picked for oral presentation, and 12 were picked for poster presentations.
