疼痛网络:一个负性信息处理系统

The Pain Matrix-A Negative Information Processing System

疼痛网络使个体能够迅速地觉察疼痛刺激并作出适应性反应,促进生存和发展。近年来,研究者普遍认为疼痛网络是一个负性的信息处理系统,这体现在它不仅负责生理疼痛,而且来自脑损伤、生理疼痛和社会疼痛共享神经基础以及调节因素在两种疼痛形式上有一致效果的证据表明它也加工形式广泛的社会疼痛。针对这一负性信息处理系统,文章从进化学和威胁性信息觉察的视角进行了解释。未来的研究可以从深入探究社会疼痛和生理疼痛共享的神经基础,进一步验证疼痛感觉成分脑区在社会疼痛中的作用以及探究引起社会疼痛的负性经历的边界入手,为疼痛网络可能充当一个负性信息处理系统提供更多的证据。

Pain maxtrix enables individual to detect pain stimulus quickly, and response adaptively and thus promotes individual＇ s survival and development. During the past few years, it has been commonly acknowledged that pain matrix is a negative information processing system in two aspects. On one hand it is in charge of physical pain. On the other hand, evidence coming from brain demonstrateds that physical and social pain shares a neural basis, suggesting that pain matrix also processes various stimuli of social pain. In view of the negative information processing system of pain maxtrix, the present paper gives explanations from perspectives of evolution and threat detection system. Future research orients researchers towards investigating the overlap of neural basis between social and physical pain, further validating the role of sensory components of pain brain regions played in social pain and exploring the boundary of negative experience causing social pain, thus verifies that social pain relies on pain maxtrix and provides more evidence on the possible role of the negative information processing system of pain maxtrix.
