Fig. 3.

Averaged pursuit responses of control and strabismic monkeys during step-ramp target motion at different speeds. In each panel, the dashed lines show the steps of target speed from 0 to 5, 10, and 15 deg/sec in each direction, and thesolid lines show averages of the evoked eye speed for at least 10 trials. A, Data from a normal monkey viewing through his right eye. B–E, Data from the two strabismic monkeys, viewing through each eye. B, Monkey SY, left eye viewing. C, Monkey SY, right eye viewing.D, Monkey PW, left eye viewing. E, Monkey PW, right eye viewing. Note the small offsets in eye speed at the start of the trace, which were caused by the small nasalward speed associated with the latent nystagmus. Upward deflections of the traces indicate rightward target and eye speed (arrows).
