微表情是短暂的面部表情，对于判断人们的真实情绪很重要。人们对识别微表情（持续时间小于 200 毫秒）和宏表达（持续时间大于 200 毫秒）的神经机制知之甚少。我们使用情感启动范式，其中面部表情图片为启动项，情感词为目标，并使用脑电图（EEG）和事件相关电位（ERP）来检查与识别微表情和宏表情相关的神经活动。结果表明，持续时间和效价对N170/顶点正电位有显着的主效应。 N400 的同余性主效应也很显着。此外，sLORETA 表明，造成这些显着差异的大脑区域包括颞下回和额叶的广泛区域。此外，结果表明，左半球比右半球更多地参与处理微表情。事件相关频谱扰动 (ERSP) 的持续时间的主要影响是显着的，与 300 ms 相比，持续时间为 40 ms 的表情识别中的 theta 振荡（4 至 8 Hz）增加。因此，与识别宏表达相比，识别微表达有不同的 EEG/ERP 神经机制。
Microexpressions are fleeting facial expressions that are important for judging people’s true emotions. Little is known about the neural mechanisms underlying the recognition of microexpressions (with duration of less than 200 ms) and macroexpressions (with duration of greater than 200 ms). We used an affective priming paradigm in which a picture of a facial expression is the prime and an emotional word is the target, and electroencephalogram (EEG) and event-related potentials (ERPs) to examine neural activities associated with recognizing microexpressions and macroexpressions. The results showed that there were significant main effects of duration and valence for N170/vertex positive potential. The main effect of congruence for N400 is also significant. Further, sLORETA showed that the brain regions responsible for these significant differences included the inferior temporal gyrus and widespread regions of the frontal lobe. Furthermore, the results suggested that the left hemisphere was more involved than the right hemisphere in processing a microexpression. The main effect of duration for the event-related spectral perturbation (ERSP) was significant, and the theta oscillations (4 to 8 Hz) increased in recognizing expressions with a duration of 40 ms compared with 300 ms. Thus, there are different EEG/ERPs neural mechanisms for recognizing microexpressions compared to recognizing macroexpressions.
