The time of occurrence of eye, head, and arm movements directed at the same visual target was measured in five human subjects. The latency of activation of the corresponding neck and arm muscles was also measured. It appears that although the overt movements are sequentially ordered (starting with the eye movement, then the head and finally the arm) the EMG discharges are synchronous with respect to the eye movement onset. In addition, eye movement latency appears definitely (though weakly) correlated with either neck or arm EMG latencies. Neck and arm EMG latencies are also mutually correlated. These results indicate a clustering of segmental motor programs for target oriented actions.
在五名人类受试者中测量了针对同一视觉目标的眼睛、头部和手臂运动的发生时间。还测量了相应颈部和手臂肌肉激活的潜伏期。似乎尽管明显的运动是按顺序进行的（从眼睛运动开始，然后是头部，最后是手臂），但肌电图放电与眼睛运动开始是同步的。此外，眼睛运动潜伏期似乎与颈部或手臂肌电图潜伏期有明确（尽管微弱）的相关性。颈部和手臂肌电图潜伏期也相互相关。这些结果表明针对目标导向动作的节段性运动程序存在聚类。
