Angular errors decrease rapidly on exposure to the perturbed brain-computer interface (BCI) mapping. A: cursor trajectories of the first 5 trials to each target on a particular day for monkey C. Colored circles represent the target locations. Solid curves and shaded areas indicate the mean and SD of the trajectories to each target. Dotted circles represent the halfway point where angular errors are assessed. B and C: angular errors (black) and success rates (green) of all trials for monkeys N and C, respectively. Shaded areas around black lines represent SE. Each data point represents the average of 20 trials to each target, subsequently smoothed with a 5-step sliding window. Gray rectangle background indicates the perturbation session.
