Figure 4. Example kinematics on cursor-jump trials. A, Top, Hand paths from monkey M for cursor-jump trials. Bottom, Reach endpoints and the 95% confidence ellipse. Solid and dashed lines denote cursor jumps away from the body and toward the body, respectively. B, SD of the hand position across trials for the narrow and wide goal reaches. C, The change in reach endpoint histograms (change relative to unperturbed reach trials). Zero denotes the mean of the reach endpoints on unperturbed trials (Fig. 2C, arrows). Arrows denote the means of the distributions. D, The mean change in reach endpoint for jumps away from the body across all recording sessions. Each session contained 10–25 perturbed trials for each perturbation direction and goal shape. E, Same as D for the SD in reach endpoints. F, G, Same as D, E for jumps toward the body. **p < 0.01, ***p < 0.001. From same recording session as Figure 2, A–C, with 20 perturbed trials for each perturbation direction and goal shape (A–C).
