情绪加工的脑机制研究及其现状

The Research on the Brain Mechanism of Emotion Processing and Its Present Condition

本文从情绪的效价载荷及其脑功能成像研究、面部表情的识别及其脑功能成像研究以及情绪的诱发及其脑功能成像研究等三方面介绍了情绪加工的脑机制及其研究现状。从现有的研究成果来看,大脑皮层在加工不同效价载荷的情绪时具有很大的重叠性;有关面部表情识别的研究表明,不同的神经环路负责调节对不同面部表情的反应;有关诱发的情绪的研究表明,前扣带回皮层在表征实验诱发的情绪时扮演着一个非常重要的角色。文章最后指出了情绪研究目前面临的一些问题,并指出在我国开展情绪的脑机制研究的重要意义。

This paper introduces the research on brain mechanism of emotion processing and the present condition from affeetive valence load and functional imaging studies, recognition of facial expression and functional imaging studies and induced emotions and their functional imaging studies. Seen from the present study condition, the emotions of different valence load recruit partly overlapped brain areas; the studies on the recognition of facial expression show that differfnt facial expressions activate different neural cireuitries; the studies on induced emotions show that the anterior eingulated cortex seems to play a very important role in presenting experiment induced emotions. Finally, the paper points out the current problems faced by emotion studies, and the significance of conducting studies on emotion in China.
