从面部表情中识别情感需要在大量神经结构中实现不同的心理过程。使用诱发电位、病变和功能成像的研究已经开始阐明一些机制。面部的早期感知处理利用枕叶和颞叶的皮层，枕叶和颞叶从面部特征的配置中构建详细的表征。随后的识别需要一系列结构，包括杏仁核和眼窝额叶皮层，它们将面部的感知表征与所发出的情绪的知识产生联系起来，这是一套使用多种策略的复杂机制。尽管最近的研究已经提供了关于成人大脑中这些机制的丰富细节，但研究也正在扩展到非人类灵长类动物、婴儿和精神疾病患者。
Recognizing emotion from facial expressions draws on diverse psychological processes implemented in a large array of neural structures. Studies using evoked potentials, lesions, and functional imaging have begun to elucidate some of the mechanisms. Early perceptual processing of faces draws on cortices in occipital and temporal lobes that construct detailed representations from the configuration of facial features. Subsequent recognition requires a set of structures, including amygdala and orbitofrontal cortex, that links perceptual representations of the face to the generation of knowledge about the emotion signaled, a complex set of mechanisms using multiple strategies. Although recent studies have provided a wealth of detail regarding these mechanisms in the adult human brain, investigations are also being extended to nonhuman primates, to infants, and to patients with psychiatric disorders.
