为了正确定位和导航，移动的动物必须获得有关其身体位置和运动的信息。动物使用各种感觉系统检测由身体加速度和旋转产生的惯性信号。在这篇综述中，我们简要总结了目前关于不同动物分类群惯性传感的知识，重点是神经元编码和感觉转导。我们概述了围绕机械感觉毛细胞建立的系统，包括脊索前庭复合体和在许多海洋无脊椎动物中看到的平衡囊。接下来，我们将这些与飞行昆虫用于管理拍打飞行的固有不稳定方面的计划进行比较，这些计划围绕可比的机械感觉细胞构建，但利用旋转系统的物理特性来促进运动编码。最后，我们强调跨类群的基本相似之处，惯性感官与视觉感官的合作，并结束了讨论的功能实用性，保持自我运动信息的编码方案的多样性。
To properly orient and navigate, moving animals must obtain information about the position and motion of their bodies. Animals detect inertial signals resulting from body accelerations and rotations using a variety of sensory systems. In this review, we briefly summarize current knowledge on inertial sensing across widely disparate animal taxa with an emphasis on neuronal coding and sensory transduction. We outline systems built around mechanosensory hair cells, including the chordate vestibular complex and the statocysts seen in many marine invertebrates. We next compare these to schemes employed by flying insects for managing inherently unstable aspects of flapping flight, built around comparable mechanosensory cells but taking unique advantage of the physics of rotating systems to facilitate motion encoding. Finally, we highlight fundamental similarities across taxa with respect to the partnering of inertial senses with visual senses and conclude with a discussion of the functional utility of maintaining a multiplicity of encoding schemes for self-motion information.
