杏仁核在恐惧识别与恐惧体验中特异性作用的分离

Dissociation of Specific Effects of Amygdala on Fear Recognition and Fear Experience

杏仁核是情绪生理机制研究的重点,具有重要的恐惧情绪功能。文章主要从杏仁核与恐惧情绪识别、恐惧情绪体验两个方面来探讨杏仁核在恐惧情绪中的作用。通过综合近期及早期研究结果发现,杏仁核并不在恐惧情绪识别中具有特异性作用,而是有着更高级的认知功能;另外,杏仁核在恐惧情绪体验中有着实质性作用,主要体现在习得、记忆与表达方面。未来研究方向可以进一步探讨杏仁核在情绪识别中的真实作用及其在联系认知与体验中的作用、杏仁核周边脑区在恐惧情绪中的作用,以及内受刺激引发的恐惧反应是否有其他脑区参与等。

The amygdala is the main emphasis in the study of psychological mechanism of emotion and possess impor-tant fear function. This study discussed the effect of amygdala on emotion of fear from two aspects： fear recognition and fearexperience. Conclusion from recent and early studies has been reviewed. Amygdala has no specific effect on fear recogni-tion but engage higher cognitive function. In addition, Amygdala plays a substantial role on fear experience with the func-tion of acquiring, remembering and expressing about fear. Future research should focus on the following areas： such as theeffect of amygdala on fear recognition and its role to connect cognition and experience, the effect of brain regions around theamygdala on fear and eventually, the effect of other brain regions except for amygdala involved in fear response which trig-gered by interoceptive stimulus.
