Multiple‐step pattern in memory‐guided saccade. (a) A 64‐year‐old male PD patient (H&Y 1) showed a completely normal performance in MGS. The target located horizontally right 20°. Blackline is the target reference curve, and the color line is the actual eye movement. (b) A 38‐year‐old male healthy control with multiple‐step pattern. (c) A 64‐year‐old female PD patient (H&Y 1) showed multiple‐step pattern when saccade to the central target at the end of the task. (d) A 61‐year‐old female PD patient (H&Y 1) showed multiple‐step pattern not only when saccade to the memory target, but also when saccade to the central target at the end of the task. (e) A 54‐year‐old male PD patient (H&Y 1) showed multiple‐step pattern in MGS and the unwanted saccades. (f) A 54‐year‐old male PD patient (H&Y 1) showed multiple‐step pattern when saccade to the central target at the end of the task. (g) A 64‐year‐old male PD patient (H&Y 2) showed multiple‐step pattern when saccade to the memory target. (h) A 51‐year‐old female MSA patient showed the typical multiple‐step pattern in MGS. (i) A 59‐year‐old female MSA patient showed hypermetria in a task. (j) A 47‐year‐old female MSA showed hypermetria and multiple‐step pattern. (k) A 64‐year‐old female MSA patient showed atypical multiple‐step pattern with the angle of multi‐step less than 90° (bold arrow). And a saccade error could be seen at the end of the mission, saccade to the opposite memorized direction. Multiple‐step pattern: solid arrow, hypermetria: dotted arrow
