The amygdala is important in emotion, but it remains unknown whether it is specialized for certain stimulus categories. We analyzed responses recorded from 489 single neurons in the amygdalae of 41 neurosurgical patients and found a categorical selectivity for pictures of animals in the right amygdala. This selectivity appeared to be independent of emotional valence or arousal and may reflect the importance that animals held throughout our evolutionary past.
杏仁核在情绪中很重要，但它是否专门用于某些刺激类别尚不清楚。我们分析了 41 名神经外科患者的 489 个单个神经元记录的反应，发现在右杏仁核中对动物图片有分类选择性。这种选择性似乎独立于情绪效价或唤醒，可能反映了动物在我们整个进化过程中的重要性。
