情绪和社会行为的迷走神经活动基础

Porges基于自主神经进化观点提出的多迷走神经理论, 区分了无髓鞘迷走神经与髓鞘迷走神经的不同功能。认为对心脏等起调控作用的髓鞘迷走神经, 经由进化逐渐与调控头面部肌肉的脑神经之间产生了神经上的联系, 成为情绪和社会行为的神经基础。已有的相关实证研究表明, 髓鞘迷走神经与个体的情绪表达与调节、社会行为以及情绪与社会行为障碍密切相关。较低的迷走神经张力、较低的迷走抑制与较低的情绪调节能力相关; 迷走抑制较高的学前儿童有较少的行为问题以及较好的社交技能; 焦虑障碍的个体表现出较低的基线迷走张力以及较低的迷走抑制水平等。多迷走神经理论及其实证研究的结果, 对于推动情绪和社会行为的自主神经基础研究具有重要的意义。

Vagal Basis of Emotion and Social Behavior

By investigating the evolution of autonomic nervous system, Porges proposed Polyvagal Theory, considering myelinated vagal nerve and unmyelinated vagal nerve have different functions. During evolution, neurological relation gradually comes into being between myelinated vagal nerve which regulates visceral state such as heart state, and the other cranial nerves which regulate the muscles of face and head, and it forms the neural substrate of emotion and social behavior. Existing empirical evidence suggests t...
