Fig. 1

Kinematic profiles of Monkeys N and C in the center-out reaching task. The four black dots indicate: movement onset, peak velocity, movement offset, and hold off (this marking applies to all figures). a Average hand trajectories, each colored trace represents a target direction (16 total). This colormap also applies to the subsequent figures. b Speed profiles pooled across all target directions with the average shown in black bold and standard deviation as the gray shaded region (n = 69 × 16 trials for Monkey N and 47 × 16 trials for Monkey C)
