We review the evidence implicating the amygdala as a critical component of a neural network of social cognition, drawing especially on research involving the processing of faces and other visual social stimuli. We argue that, although it is clear that social behavioral representations are not stored in the amygdala, the most parsimonious interpretation of the data is that the amygdala plays a role in guiding social behaviors on the basis of socioenvironmental context. Thus, it appears to be required for normal social cognition. We propose that the amygdala plays this role by attentionally modulating several areas of visual and somatosensory cortex that have been implicated in social cognition, and in helping to direct overt visuospatial attention in face gaze. We also hypothesize that the amygdala exerts attentional modulation of simulation in somatosensory cortices such as supramarginal gyrus and insula. Finally, we argue that the term emotion be broadened to include increased attention to bodily responses and their representation in cortex.
我们回顾了有关杏仁核作为社会认知神经网络关键组成部分的证据，特别借鉴了涉及面部及其他视觉社会刺激处理的研究。我们认为，尽管很明显社会行为表征并非存储在杏仁核中，但对数据最简洁的解释是，杏仁核在基于社会环境背景指导社会行为方面发挥作用。因此，它似乎是正常社会认知所必需的。我们提出，杏仁核通过注意力调节与社会认知相关的视觉和体感皮层的多个区域，并在帮助引导面部注视中的明显视觉空间注意力方面发挥这一作用。我们还假设，杏仁核在诸如缘上回和脑岛等体感皮层中对模拟进行注意力调节。最后，我们认为“情绪”一词应拓宽，以包括对身体反应及其在皮层中的表征的更多关注。
