This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. A central tenet of emotion theory is that emotions impose coherence across autonomic, experiential, and neural response systems. However, previous studies that have probed the neural bases of emotion have not assessed autonomic, experiential, and neural responses with a temporal resolution that makes it possible to discern the dynamic relations among these three systems as the emotion unfolds over time. In order to assess the degree of coherence across multiple indices of a temporally evolving emotional response, 24 participants were imaged while watching a series of 2-minute sad, amusing and neutral film clips. During film viewing, continuous measures of physiological arousal (skin conductance, heart rate and respiration) and dynamic subjective report of emotion experience were collected for all participants. Neural signal correlating with autonomic responses and the self-reported experience of sadness and amusement were found in regions in cingulate and superior frontal cortices, parietal cortex, as well as the insula and cerebellum, areas known to be sensitive both to emotional experience and autonomic changes.

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。情绪理论的一个核心原则是，情绪在自主、经验和神经反应系统之间施加一致性。然而，先前的研究已经探索了情绪的神经基础，并没有评估自主、经验和神经反应的时间分辨率，这使得有可能辨别这三个系统之间的动态关系，随着时间的推移，情绪展开。为了评估暂时演变的情绪反应的多个指标之间的一致性程度，24名参与者在观看一系列2分钟的悲伤、有趣和中性电影片段时拍摄了图像。在观看电影期间，收集所有参与者的连续生理唤醒测量（皮肤电导、心率和呼吸）和动态主观情绪体验报告。研究人员在扣带皮层、额叶上部皮层、顶叶皮层、脑岛和小脑等区域发现了与自主神经反应和自我报告的悲伤和娱乐体验相关的神经信号，这些区域已知对情绪体验和自主神经变化都很敏感。T
