Saccade kinematics and saccade precision for monkeys JL (left) and F (right). Only saccade end points from hit trials are included. A: saccade duration as a function of eccentricity. Duration was calculated from the eye velocity trace as the time from when the velocity first exceeded the threshold (25°/s) to when it returned to threshold. B: saccade peak velocity as a function of eccentricity. C: saccade end-point spread as a function of eccentricity. The spread of the saccade end-point clusters is derived from the area of the ellipse fit to the cluster of end points at each target location.
