Typical examples of the initiation and maintenance of pursuit for step-ramp target motion in control and strabismic monkeys. In each panel, the dashed traces show target speed and position, and the solid traces show eye speed and position. A, One example of the initiation of pursuit for viewing through the right eye in a monkey with normal eye alignment. Target motion is rightward, which is temporalward with respect to the viewing eye. B, One example of the initiation of pursuit from a strabismic monkey (SY), viewing nasalward (rightward) target motion through his left eye. C, A similar example from the same strabismic monkey (SY), viewing temporalward (leftward) target motion through his left eye.Upward deflections of the traces indicate rightward target and eye motion (arrows).
