Abstract: 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

Key words: emotion, amygdala, lateralization, functional neuroimaging
