Continuous decoding performance. Decoding performance of center-out trajectories for the frequency band 0.1–2 Hz. The boxplot represents the Pearson correlation coefficient obtained after computing a cross-fold validation between all runs (n=10). On each box, the central mark is the median, the edges of the box are the 25th and 75th percentiles, the whiskers extend to the most extreme datapoints which are considered not outliers, and the outliers are plotted individually. For each subject (1–5) the graph shows results for position (Px and Py) and velocity (Vx and Vy)
