The institution listed isfor 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.
