Abstract
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.
摘要
人类和动物的行为表现出幂律相关性，其起源存在争议。在这项工作中，记录了实验室啮齿动物在几天内的自发运动。研究发现，动物运动是无标度的，并且这种标度是由其长度以及特定的顺序引起的不活动停顿引入的。此外，在事件发生的速率中也可以证明这种标度。与人类的相关结果进行了比较，并讨论了候选模型，以提供此类动力学起源的线索。
