最近的一项案例研究发现，杏仁核双侧受损会损害对恐惧声音表达的正常评估。然而，这种听觉情绪处理障碍的唯一证据来源是杏仁体外损伤的患者，其中可能包括基底节，这已被证明对韵律评估很重要。在这项研究中，我们提供了对一名女性患者的声音恐惧表达进行保留评估的证据(S.P.)双侧杏仁核受损，但基底神经节完好。这位患者此前曾被证明在评估面部表情方面存在障碍，包括恐惧。这些结果表明，对来自不同输入渠道的非语言恐惧信号的分析是可分离的，至少部分依赖于不同的大脑结构。我们认为杏仁核与基底节一起，可能支持对危险听觉信号的正常评估。
A recent case study found that bilateral damage to the amygdala impairs the normal appraisal of vocal expressions of fear. However, the single source of evidence for this auditory emotion-processing impairment is from a patient with extra-amygdaloid damage that may include the basal ganglia, which have been shown to be important for prosody evaluation. In this study we provide evidence of preserved evaluation of vocal expressions of fear in a female patient (S.P.) with bilateral damage to the amygdala but with intact basal ganglia. This same patient has previously been shown to be impaired in the evaluation of facial expressions, including fear. These results indicate that the analysis of nonverbal signals of fear from different input channels are dissociable, being at least partially dependent on different brain structures. We suggest that the amygdala, in conjunction with the basal ganglia, may support the normal appraisal of auditory signals of danger.
