对5名智力一般或高于平均水平的脑炎后遗症患者进行了人脸加工和面部情绪识别的研究。其中四个人(JC、YW、RB和SE)在杏仁核区域有广泛的损伤。第五位脑炎后患者主要是海马区受损，杏仁核(RS)相对较少，这使我们能够对比包括和不包括杏仁体区域在内的颞叶损伤的影响。研究结果显示，包括杏仁核在内的双侧颞叶受损后，患者对恐惧的识别能力受损。对于JC来说，这是一系列面部处理任务缺陷的一部分，对几种情绪的识别能力受损。然而，Se、YW和Rb显示出相对有限的赤字。虽然他们在识别或命名著名面孔方面都有一些问题，在沃灵顿识别记忆测试中对面孔的记忆力很差，但在本顿面部识别测试中没有表现出明显的障碍，这表明他们对面孔的物理结构的感知相对较好。在对基本情绪(快乐、惊讶、恐惧、悲伤、厌恶和愤怒)的识别测试中，SE、YW和RB在除恐惧之外的所有情绪上的表现与我们的对照组相比都达到了正常水平。他们的结果与RS的结果形成对比，杏仁核区域相对较少，对情绪的识别没有受到影响，清楚地表明杏仁核在识别恐惧方面的重要性。(C)1998由爱思唯尔科学有限公司出版。版权所有。
Face processing and facial emotion recognition were investigated in five post-encephalitic people of average or above-average intelligence. Four of these people (JC, YW, RB and SE) had extensive damage in the region of the amygdala. A fifth postencephalitic person with predominantly hippocampal damage and relative sparing of the amygdala (RS) participated, allowing us to contrast the effects of temporal lobe damage including and excluding the amygdala region. The findings showed impaired recognition of fear following bilateral temporal lobe damage when this included the amygdala. For JC, this was part of a constellation of deficits on face processing tasks, with impaired recognition of several emotions. SE, YW and RB, however, showed relatively circumscribed deficits. Although they all had some problems in recognizing or naming famous faces, and had poor memory for faces on the Warrington Recognition Memory Test, none showed a significant impairment on the Benton Test of Facial Recognition, indicating relatively good perception of the face's physical structure. In a test of recognition of basic emotions (happiness, surprise, fear, sadness, disgust and anger), SE, YW and RB achieved normal levels of performance in comparison to our control group for all emotions except fear. Their results contrast with those of RS, with relative sparing of the amygdala region and unimpaired recognition of emotion, pointing clearly toward the importance of the amygdala in the recognition of fear.
