情绪大脑机制研究的进展

文章综述情绪大脑机制研究的最新进展。情绪的脑机制——大脑回路，包括前额皮层、杏仁核、海马、前部扣带回、腹侧纹状体等。前额皮层中的不对称性与趋近和退缩系统有关，左前额皮层与趋近系统和积极感情有关，右前额皮层与消极感情和退缩有关。杏仁核易被消极的感情刺激所激活，尤其是恐惧。海马在情绪的背景调节中起着重要作用。前额皮层和杏仁核激活不对称性的个体差异是情绪个体差异的生理基础。情绪的中枢回路有可塑性。

Research on Brain Mechanisms of Emotion

This article reviews the latest research on brain mechanisms of emotion. The brain circuitry underlying emotion includes the prefrontal cortex, the amygdala, hippocampus, anterior cingulate, ventromedial striatum and et al. Asymmetries in the PFC have been linked to approach and withdrawal systems,with sectors of the left PFC more associated with the approach system and certain forms of positive affect and other regions in the right PFC more associated with negative affect and withdrawal. The amygdala is activated by stimulus that elicits certain forms of negative affect, particularly fear. The hippocampus plays an important role in the context-regulation of emotion. Asymmetries in the PFC and the amygdala are the physiological bases of individual difference in emotion. There is plasticity in the central circuitry of emotion.
