Figure 2.

Effect of repetitive coupling of saccades with SC stimulation. Sample records are collected before (pre), during (stim), and after (post) stimulation session in monkey H. Black and gray traces indicate eye and target positions, respectively (horizontal and vertical). Each panel contains traces for 7–9 saccades. Only leftward saccades were coupled with stimulation in this experiment. Striped bars indicate the time over which the target was blanked (broken lines in target traces). Rt, Rightward; Lt, leftward; Up, upward; Dn, downward.
