功能性神经影像学和基于病变的神经心理学实验已经证明了人类杏仁核岛在识别由感官刺激发出的某些情绪信号，特别是：面部表情中的恐惧和愤怒。我们在一个罕见的双侧杏仁核完全损伤的受试者中检查了两个情绪维度的识别，唤醒和效价。对于描述不愉快情绪的面部表情、词语和服务，尤其是关于恐惧和愤怒，情绪唤醒的识别受损。然而，情绪效价的识别是正常的。研究结果表明，杏仁核在有关负面情绪唤起的知识中发挥着关键作用，这一功能可以解释双侧杏仁核损伤患者对恐惧和愤怒的识别能力受损，并且与杏仁核的极点一致。处理与威胁和危险相关的刺激。
Functional neuroimaging and lesion-based neuropsychological experiments have demonstrated the human amygdala's isle in recognition of certain emotions signaled by sensory stimuli, notably: fear and anger in facial expression. We examined recognition of two emotional dimensions, arousal and valence, in a rare subject with complete, bilateral damage restricted to the amygdala. Recognition of emotional arousal was impaired for facial expressions, words, and services that depicted unpleasant emotions, especially in regard to fear ann anger. However recognition of emotional valence was normal. The findings suggest that the amygdala plays a critical role in knowledge concerning the arousal of negative emotions, a function that may explain the impaired recognition of fear and anger in patients with bilateral amygdala damage, and one that is consistent with the amygdala's pole in processing stimuli related to threat and danger.
