正在进行的大脑相互感觉信号和情绪过程之间的关系仅通过外部刺激锁定措施间接解决。在这项研究中，身体内部触发(心脏诱发电位，HEP)被用来测量情绪状态下正在进行的内部触发信号。我们使用高密度脑电(HD-EEG)、源重建分析和行为测量来评估观看情绪诱导视频剪辑(积极、消极和中性情绪)的健康参与者。结果表明，HEP在与情感-认知整合相关的额叶-绝缘-时间网络的特定源空间节点上的情绪调制。这项研究首次通过动态刺激呈现来评估内脏感觉皮质标志物和情绪的连续触发之间的直接趋同。(C)2015爱思唯尔B.V.保留所有权利。
The relationship between ongoing brain interoceptive signals and emotional processes has been addressed only indirectly through external stimulus-locked measures. In this study, an internal body trigger (heart evoked potential, HEP) was used to measure ongoing internally triggered signals during emotional states. We employed high-density electroencephalography (hd-EEG), source reconstruction analysis, and behavioral measures to assess healthy participants watching emotion-inducing video-clips (positive, negative, and neutral emotions). Results showed emotional modulation of the HEP at specific source-space nodes of the fronto-insulo-temporal networks related to affective-cognitive integration. This study is the first to assess the direct convergence among continuous triggers of viscerosensory cortical markers and emotion through dynamic stimuli presentation. (C) 2015 Elsevier B.V.
