In this week’s Science, Richard Andersen’s lab shows the first use of a region (relatively) distant from primary motor areas for brain readout in a reaching task. Using a very small number of neurons (8-16 cells), the investigators were able to achieve a 60-70% accuracy in predicting reach movements to a particular target (out of 8 total targets). Read on for the abstract or here for the full article.
