大多数动物物种都具有评估行驶距离的能力。头部在空间中的轨迹是根据视觉、前庭和体感系统的汇聚信号以及运动命令的传出副本来测量的。最近的人类研究证据表明，头部在空间中的轨迹可以存储在空间记忆中。然而，一个基本问题仍未得到解答：运动如何存储？在这项研究中，被要求在蒙住眼睛的情况下重现被动线性全身位移距离的人也能够重现速度分布。这一发现表明，运动的时空动态模式被存储，并且可以通过使用前庭和感觉线索来检索。
The ability to evaluate traveled distance is common to most animal species. Head trajectory in space is measured on the basis of the converging signals of the visual, vestibular, and somatosensory systems, together with efferent copies of motor commands. Recent evidence from human studies has shown that head trajectory in space can be stored in spatial memory. A fundamental question, however, remains unanswered: How is movement stored? In this study, humans who were asked to reproduce passive linear whole-body displacement distances while blindfolded were also able to reproduce velocity profiles. This finding suggests that a spatiotemporal dynamic pattern of motion is stored and can be retrieved with the use of vestibular and somesthetic cues.
