为了探讨杏仁核在人类情绪认知中的功能，我们研究了对掩蔽视觉刺激的皮电活动（EDA）。对6例单侧颞叶切除术后癫痫患者进行了研究。在阈下或阈上条件下，将来自国际情感图片系统的具有独立效价的摄影幻灯片（10张阴性，10张中性）呈现给他们的单侧视野。大脑半球和情绪效价之间的相互作用，发现只有在阈下条件下，更大的EDA反应相比，中性的负面刺激时，观察到刺激呈现给完整的半球。研究结果表明，无意识的情绪处理反映在EDA从有意识的情绪处理不同的方式。因此，内侧颞叶结构，包括杏仁核，似乎在这种自动处理的神经基质中起着关键作用。
To investigate the function of the amygdala in human emotional cognition, we investigated the electrodermal activity (EDA) in response to masked (unseen) visual stimuli. Six epileptic subjects were investigated after unilateral temporal lobectomy. Emotionally valenced photographic slides (10 negative, 10 neutral) from the International Affective Picture System were presented to their unilateral visual fields under either subliminal or supraliminal conditions. An interaction between hemispheres and emotional valences was found only under the subliminal conditions; greater EDA responses to negative stimuli compared with neutral ones were observed when stimuli were presented to the intact hemispheres. The findings suggest that nonconscious emotional processing is reflected in EDA in a different manner from conscious emotional processing. Medial temporal structures, including the amygdala, thus appear to play a critical role in the neural substrates for this automatic processing.
