摘要

脊索动物的尾巴在形态和功能上表现出相当大的多样性,长度、直径和质地各不相同,以适应不同的生态作用。虽然包括人类在内的一些动物已经失去或减少了尾巴,但许多脊椎动物仍保留并使用尾巴进行平衡、攀爬和躲避捕食者等活动。本研究调查了实验室小鼠(Mus musculus)在面对外部和自身产生的扰动时如何利用尾巴保持平衡。小鼠穿过不同宽度的平台,同时对滚动平面的倾斜做出反应。我们的研究结果表明,小鼠摆动尾巴来抵消外部滚动扰动,产生角动量以稳定自身。我们还发现,小鼠在狭窄平台上运动时,会使用主动(动态稳定器)和被动(配重)的尾巴运动策略。研究结果表明,尾部是小鼠运动的核心组成部分,尤其是在具有挑战性的平衡条件下。

The role of mouse tails in response to external and self-generated balance perturbations on the roll plane.

Chordate tails exhibit considerable morphological and functional diversity, with variations in length, diameter and texture adapted to various ecological roles. While some animals, including humans, have lost or reduced their tails, many vertebrates retain and use their tails for activities such as balancing, climbing and escaping predators. This study investigates how laboratory mice (Mus musculus) use their tails to maintain balance when dealing with external and self-generated perturbations. Mice crossed platforms of different widths, while responding to roll-plane tilts. Our findings show that mice swing their tails to counteract external roll perturbations, generating angular momentum to stabilize themselves. Mice were also found to use active (dynamic stabilizer) and passive (counterweight) tail movement strategies when locomoting on narrow platforms. The results suggest that the tail is a core component of mouse locomotion, especially in challenging balancing conditions.
