FIG. 2.

Single trial record showing a representative response to target motion at an apparent velocity of 22°/s, with a Δt of 16 ms. The top and bottom pairs of traces superimpose target (T) and eye (E) velocity and position, respectively. The dots on the target position trace indicate the time and position of each flash of the apparent motion target. The arrow on the eye position trace points out a saccade. The arrow on the eye velocity trace points out the (truncated) rapid upward deflection caused by the saccade. The traces begin 100 ms before the step-ramp of target motion, and about 1,000 ms after the onset of the trial. Upward deflections of the traces indicate rightward motion.
