综述了最近事件相关脑电位(ERP)研究的结果，这些研究涉及到情绪面部表情的检测和分析的脑过程。在所有实验中，与中性面孔相比，情绪化面孔会触发更高的事件相关电位正性。这种情绪表达效应的出现非常早，在不同的实验中，在有或没有面孔分心刺激的情况下，面孔要么在注视时呈现，要么在侧面呈现，刺激后的时间从120到180毫秒不等。虽然在之前的非面部刺激研究中发现了刺激后超过250毫秒的广泛分布的积极偏向，但这种情绪积极的早期额部中央分布阶段最有可能是特定于面部的。在六种基本情绪中发现了类似的情绪表达效应，这表明这些效应主要不是在专门用于自动检测特定情绪的神经结构中产生的。当注意力从外围呈现的情绪面孔的位置转移时，表情效应被消除，这表明它们与预先注意的情绪处理无关。当中心凹面部无人看管时，表情效应会减弱，但不会完全消除。我们认为，情绪面孔加工的这些事件相关电位反映了新皮质系统内的活动，在新皮质系统中，情绪内容的表征是以任务依赖的方式产生的，以实现对行为的适应性有意控制。鉴于这里回顾的情绪特异性效应的早期开始，这个系统很可能与正在进行的杏仁核和相关皮质下大脑回路中的情绪内容评估同步激活。
Results from recent event-related brain potential (ERP) studies investigating brain processes involved in the detection and analysis of emotional facial expression are reviewed. In all experiments, emotional faces were found to trigger an increased ERP positivity relative to neutral faces. The onset of this emotional expression effect was remarkably early, ranging from 120 to 180 ms post-stimulus in different experiments where faces were either presented at fixation or laterally, and with or without non-face distractor stimuli. While broadly distributed positive deflections beyond 250 ms post-stimulus have been found in previous studies for non-face stimuli, the early frontocentrally distributed phase of this emotional positivity is most likely face-specific. Similar emotional expression effects were found for six basic emotions, suggesting that these effects are not primarily generated within neural structures specialised for the automatic detection of specific emotions. Expression effects were eliminated when attention was directed away from the location of peripherally presented emotional faces, indicating that they are not linked to pre-attentive emotional processing. When foveal faces were unattended, expression effects were attenuated, but not completely eliminated. It is suggested that these ERP correlates of emotional face processing reflect activity within a neocortical system where representations of emotional content are generated in a task-dependent fashion for the adaptive intentional control of behaviour. Given the early onset of the emotion-specific effects reviewed here, it is likely that this system is activated in parallel with the ongoing evaluation of emotional content in the amygdala and related subcortical brain circuits.
