人类和动物的行为表现出幂律相关性，其起源是有争议的。在这项工作中，实验室啮齿动物的自发运动记录了几天。结果发现，动物的运动是无标度的，缩放是由不活动的停顿，其长度以及其特定的顺序。此外，在事件发生率中也可证明比例关系。与人类的相关结果进行了比较，并讨论了候选模型，为这种动态的起源提供线索。
Human and animal behavior exhibits power law correlations whose origin is controversial. In this work, the spontaneous motion of laboratory rodents was recorded during several days. It is found that animal motion is scale-free and that the scaling is introduced by the inactivity pauses both by its length as well as by its specific ordering. Furthermore, the scaling is also demonstrable in the rates of event's occurrence. A comparison with related results in humans is made and candidate models are discussed to provide clues for the origin of such dynamics.
