观察别人痛苦会产生一种共同的情感体验，这种体验主要激活大脑中处理疼痛的情感成分的区域。然而，偶尔，感觉区域也会被激活，有轶事报道说，人们会分享别人痛苦的身体和情感成分。在这里，我们向一大群正常对照者展示了一系列描绘有害事件的图像或短片。大约三分之一的样本报告了对一个或多个图像或片段的实际有害的身体体验。随后，10名对疼痛有反应的人被招募，并与10名无反应的人配对，参加功能磁共振成像研究。受试者在观察有害事件的静态图像时被扫描。与不包含有害事件的情绪图像相比，反应者激活了与疼痛相关的情绪和感觉大脑区域，而无反应者激活的很少。这些发现提供了令人信服的证据，表明一些人在观察他人的疼痛时，很容易体验到疼痛的情感和感官成分，从而产生共同的身体疼痛体验。
Observing someone else in pain produces a shared emotional experience that predominantly activates brain areas processing the emotional component of pain. Occasionally, however, sensory areas are also activated and there are anecdotal reports of people sharing both the somatic and emotional components of someone else's pain. Here we presented a series of images or short clips depicting noxious events to a large group of normal controls. Approximately one-third of this sample reported an actual noxious somatic experience in response to one or more of the images or clips. Ten of these pain responders were subsequently recruited and matched with 10 non-responders to take part in an fMRI study. The subjects were scanned while observing static images of noxious events. In contrast with emotional images not containing noxious events the responders activated emotional and sensory brain regions associated with pain while the non-responders activated very little. These findings provide convincing evidence that some people can readily experience both the emotional and sensory components of pain during observation of other's pain resulting in a shared physical pain experience.
