EXPLORING EMOTION COHERENCE: RESPONSES DURING AMUSEMENT AND SADNESS

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。情绪理论的一个中心原则是，情绪在自主、经验和神经反应系统之间施加连贯性。然而，以前的研究探索了情绪的神经基础，并没有用时间分辨率来评估自主、经验和神经反应，这使得随着情绪随着时间的推移而揭示这三个系统之间的动态关系成为可能。为了评估在时间上演变的情绪反应的多个指数的一致性程度，24名参与者在观看一系列2分钟的悲伤、有趣和中性的电影片段时被拍摄成图像。在观看电影时，收集所有参与者的生理唤醒(皮肤电导、心率和呼吸)的连续测量和情绪体验的动态主观报告。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在扣带回和额叶上皮质、顶叶皮质以及岛叶和小脑的区域被发现，这些区域已知对情绪体验和自主神经变化都很敏感。T

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.
