During global health crises, such as the recent H1N1 pandemic, the mass media provide the public with timely information regarding risk. To obtain new insights into how these messages are received, we measured neural data while participants, who differed in their preexisting H1N1 risk perceptions, viewed a TV report about H1N1. Intersubject correlation (ISC) of neural time courses was used to assess how similarly the brains of viewers responded to the TV report. We found enhanced intersubject correlations among viewers with high-risk perception in the anterior cingulate, a region which classical fMRI studies associated with the appraisal of threatening information. By contrast, neural coupling in sensory-perceptual regions was similar for the high and low H1N1-risk perception groups. These results demonstrate a novel methodology for understanding how real-life health messages are processed in the human brain, with particular emphasis on the role of emotion and differences in risk perceptions.
在全球健康危机期间，例如最近的 H1N1 大流行期间，大众媒体为公众提供有关风险的及时信息。为了深入了解这些信息是如何被接收的，我们在参与者观看有关 H1N1 的电视报道时测量了他们的神经数据。使用神经时间序列的主体间相关性（ISC）来评估观看者的大脑对电视报道的反应有多相似。我们发现，在前扣带皮层中，高风险感知的观看者之间的主体间相关性增强，而经典 fMRI 研究将该区域与威胁信息的评估相关联。相比之下，高 H1N1 风险感知组和低 H1N1 风险感知组的感觉知觉区域的神经耦合相似。这些结果展示了一种用于理解人类大脑如何处理现实生活中的健康信息的新方法，特别强调了情绪和风险感知差异的作用。
