最近的神经影像学和神经心理学工作已经开始阐明大脑如何对观察情绪的面部表情做出反应。然而，在这个层面上还没有研究过的一个重要的面部表情类别是痛苦的面部表情。我们通过功能性磁共振成像（fMRI）研究了受试者对疼痛表达的神经反应，受试者观看了短视频序列，这些视频序列显示了中度疼痛或无疼痛的面部表情。在交替的块中，相同的受试者接受疼痛和非疼痛的热刺激。疼痛的面部表情被发现参与了第一手疼痛体验的皮层区域，包括前扣带皮层和皮层。报告的研究结果证实了其他工作，其中目睹疼痛的神经反应已从其他角度进行了检查。此外，他们还支持这样的观点，即共同的神经基质参与代表自己和他人的情感状态。(C)2004年爱思唯尔公司All rights reserved.
Recent neuroimaging and neuropsychological work has begun to shed light on how the brain responds to the viewing of facial expressions of emotion. However, one important category of facial expression that has not been studied on this level is the facial expression of pain. We investigated the neural response to pain expressions by performing functional magnetic resonance imaging (fMRI) as subjects viewed short video sequences showing faces expressing either moderate pain or, for comparison, no pain. In alternate blocks, the same subjects received both painful and non-painful thermal stimulation. Facial expressions of pain were found to engage cortical areas also engaged by the first-hand experience of pain, including anterior cingulate cortex and insula. The reported findings corroborate other work in which the neural response to witnessed pain has been examined from other perspectives. In addition, they lend support to the idea that common neural substrates are involved in representing one's own and others' affective states. (C) 2004 Elsevier Inc. All rights reserved.
