杏仁核情绪功能偏侧化的成像研究述评

从意识水平、性别、情绪类型3个方面讨论了大脑两半球杏仁核在情绪功能方面表现出的不对称性。初步证据显示大脑两侧的杏仁核功能的确存在偏侧化，并且与右侧杏仁核相比，左侧杏仁核出现更多激活。右侧杏仁核可能负责的是早期的、基础的、不易被检测到的“幕后”的情绪工作；左侧杏仁核负责随后具体的、持续的、容易被检测到的“幕前”的情绪工作。由于目前针对杏仁核偏侧化的专门研究不多，其具体机制不清楚。该文还对杏仁核偏侧化的理论假设和未来研究方向做了简要的介绍

On Functional Lateralization of Amygdala Involved in Emotion

Functional lateralization of amygdala involved in emotion is reviewed from three aspects:conscious level,sex,emotional type.Indeed,the function of amygdala is asymmetry,and left amygdala shows more active than right amygdala.Right amygdala is responsible for early stage,basic,backstage emotion activities which is not easy to be tested,and left amygdala involves followed,concrete,sustained,proscenium emotion activities which is easy to be tested.It is not very clear about its mechanism of functional lateralization.The hypothesis and prospects on future studies about lateralization of amygdala are also reviewed in the paper.
