摘要: 行为抑制是一种重要的执行功能。考察情绪影响行为抑制的脑机制, 将有助于理解个体如何适应环境, 特别是如何在情绪情境中控制自己的行为。近年来, 研究者开始使用脑成像技术考察情绪影响行为抑制的脑机制。研究发现, 在情绪影响行为抑制的过程中不仅涉及前额叶抑制控制系统和边缘结构情绪加工系统, 而且涉及这两个系统的相互作用, 即情绪加工与行为抑制加工的整合。腹外侧前额皮层、背外侧前额皮层、前扣带回、杏仁核、脑岛等脑区在情绪加工与行为抑制加工的整合中起着重要的作用, 但情绪整合到行为抑制加工中的时间进程还不清楚。今后的研究应着眼于情绪影响行为抑制的时间进程、神经网络、个体差异的影响以及改进研究范式等方向。

Abstract: It is very important to withhold improper behaviors in emotional situations. Recently, brain imaging technologies have been applied to investigate the neural mechanisms of how emotion affects behavioral inhibition. According to these findings, behavioral inhibition in emotional contexts requires an interaction of inhibitory and emotional processes that recruits brain regions beyond those engaged by either process alone. At the neural substrate level, the ventrolateral prefrontal cortex, dorsolateral prefrontal cortex, anterior cingulate cortex, insular cortex and amygdala were involved in the integration of emotional information and the behavioral inhibition process. However, the time course of the integration process is still unclear. Individual differences (age, gender and personality) and emotional factors (valence and arousal) also mediated the effects of emotion affecting inhibition in neural level. Future studies should focus on identifying to what extent and when the integration and dissociation between emotion and inhibition processes occur.
