The polyvagal theory introduced a new perspective relating autonomic function to behavior, that included an appreciation of the autonomic nervous system as a "system," the identification of neural circuits involved in the regulation of autonomic state, and an interpretation of autonomic reactivity as adaptive within the context of the phylogeny of the vertebrate autonomic nervous system. The paper has two objectives: first, to provide an explicit statement of the theory; and second, to introduce the features of a polyvagal perspective. The polyvagal perspective emphasizes how an understanding of neurophysiological mechanisms and phylogenetic shifts in neural regulation leads to different questions, paradigms, explanations, and conclusions regarding autonomic function in biobehavioral processes than peripheral models. Foremost, the polyvagal perspective emphasizes the importance of phylogenetic changes in the neural structures regulating the autonomic nervous system and how these phylogenetic shifts provide insights into the adaptive function and the neural regulation of the two vagal systems.
多元迷走神经理论引入了一种将自主神经功能与行为相关联的新视角，其中包括将自主神经系统视为一个“系统”，识别参与自主神经状态调节的神经回路，以及在脊椎动物自主神经系统的系统发育背景下将自主神经反应性解释为适应性反应。本文有两个目标：第一，对该理论进行明确阐述；第二，介绍多元迷走神经视角的特点。多元迷走神经视角强调，与外周模型相比，理解神经生理机制和神经调节中的系统发育变化如何导致关于生物行为过程中自主神经功能的不同问题、范式、解释和结论。最重要的是，多元迷走神经视角强调调节自主神经系统的神经结构中系统发育变化的重要性，以及这些系统发育转变如何为两个迷走神经系统的适应性功能和神经调节提供见解。
