Monkeys generated disjunctive smooth pursuit eye movements when they tracked visual targets that moved toward or away from them. Eye acceleration was computed during the initial 100 msec of pursuit (the open-loop interval) for various target trajectories. The initial acceleration of either eye was a function of the target's motion with respect to that eye, regardless of whether or not the pursuit was conjugate or disjunctive, or performed with one eye occluded. Eye movements produced by fusional vergence could be separated temporally from eye movements produced by smooth pursuit using step-ramp paradigms. The separation of the two responses demonstrates that the fusional vergence system operates in parallel with the smooth pursuit system, presumably to minimize disparity, but not to generate disjunctive components of smooth pursuit eye movements.
当猴子追踪朝着它们或远离它们移动的视觉目标时，会产生分离的平滑跟踪眼球运动。在各种目标轨迹的跟踪初始100毫秒（开环间隔）期间计算眼球加速度。任何一只眼睛的初始加速度都是目标相对于该眼睛运动的函数，无论跟踪是共轭的还是分离的，或者是在一只眼睛被遮挡的情况下进行的。使用阶梯斜坡范式，可以在时间上区分融合性聚散产生的眼球运动和平滑跟踪产生的眼球运动。这两种反应的区分表明，融合性聚散系统与平滑跟踪系统并行运作，大概是为了尽量减少视差，但不是为了产生平滑跟踪眼球运动的分离成分。
