通过记录猴子的颈部和眼部肌肉来研究眼-头协调。结果表明，（i）在眼头转动过程中，神经活动在眼肌之前到达颈部肌肉，（ii）无论初始头部位置如何，所有激动性颈部肌肉都同时激活。由于眼睛的明显运动先于头部的运动，因此可以得出结论，中枢神经命令启动了眼睛-头部序列，但没有指定其序列顺序。此外，还确定了补偿性眼球运动不是从中央发起的，而是依赖于由头部运动引起的反射激活。
Eye-head coordination was investigated by recording from the neck and eye muscles in monkeys. The results show that (i) during eye-head turning, neural activity reaches the neck muscles before the eye muscles, and (ii) all agonist neck muscles are activated simultaneously regardless of the initial head position. Since overt movement of the eyes precedes that of the head, it was concluded that the central neural command initiates the eye-head sequence but does not specify its serial order. Furthermore, it was determined that the compensatory eye movement is not initiated centrally but instead is dependent upon reflex activation arising from movement of the head.
