查尔斯·达尔文提出，通过迷走神经（第十脑神经），情绪面部表情得以进化、适应并发挥着至关重要的交流功能。根据这一观点，后来发展的多迷走神经理论认为迷走神经是调节情绪和社会行为的关键系统发育基质。多迷走神经理论假设最佳的社交互动，包括对面部情绪的识别，是由迷走神经调节的。到目前为止，在人类中，尚未证明迷走神经在情绪识别中起着因果作用。为了研究这一点，我们采用了经皮迷走神经刺激（tVNS），这是一种新型的非侵入性脑刺激技术，通过自下而上的机制调节大脑活动。采用假手术/安慰剂对照、受试者内随机交叉设计来推断受刺激的迷走神经与识别情绪的相关能力之间的因果关系，如在 38 名健康年轻志愿者中进行的“从眼中读心”测试所索引的那样。与假刺激相比，主动 tVNS 增强了对简单物品的情绪识别，这表明它提高了解码显着社交线索的能力。我们的结果证实迷走神经与情绪识别有因果关系，支持达尔文的论点。 (C) 2017 Elsevier Ltd. 保留所有权利。
Charles Darwin proposed that via the vagus nerve, the tenth cranial nerve, emotional facial expressions are evolved, adaptive and serve a crucial communicative function. In line with this idea, the later-developed polyvagal theory assumes that the vagus nerve is the key phylogenetic substrate that regulates emotional and social behavior. The polyvagal theory assumes that optimal social interaction, which includes the recognition of emotion in faces, is modulated by the vagus nerve. So far, in humans, it has not yet been demonstrated that the vagus plays a causal role in emotion recognition. To investigate this we employed transcutaneous vagus nerve stimulation (tVNS), a novel non-invasive brain stimulation technique that modulates brain activity via bottom-up mechanisms. A sham/placebo-controlled, randomized cross-over within-subjects design was used to infer a causal relation between the stimulated vagus nerve and the related ability to recognize emotions as indexed by the Reading the Mind in the Eyes Test in 38 healthy young volunteers. Active tVNS, compared to sham stimulation, enhanced emotion recognition for easy items, suggesting that it promoted the ability to decode salient social cues. Our results confirm that the vagus nerve is causally involved in emotion recognition, supporting Darwin's argumentation. (C) 2017 Elsevier Ltd. All rights reserved.
