Humans explore their visual environment through orienting movements that rapidly change their line of sight. Small saccadic eye movements made without head movements are arguably the best understood volitional movement made by humans. However, because the eyes are nested within a mobile head, the oculomotor system evolved to control gaze, and large gaze shifts are brought about by coordinated movements of the eyes and head (gaze = eye-in-space = eye-in-head + head-in-space). The ubiquity, rapidity, and accuracy of eye-head gaze shifts make it a model system for understanding how the brain coordinates multi-segmental motion.

人类通过快速改变视线的定向运动来探索他们的视觉环境。在没有头部运动的情况下进行的小扫视运动可以说是人类所做的最好理解的意志运动。然而，由于眼睛嵌套在移动的头部中，眼动系统进化为控制凝视，并且大的凝视移动由眼睛和头部的协调运动引起（凝视=眼在空间=眼在头部+头在空间）。眼-头凝视转移的普遍性、快速性和准确性使其成为理解大脑如何协调多节段运动的模型系统。
