大脑主要视觉区域的破坏会导致皮质性失明。在这里，我们报告一个受试者，在他的视觉皮质双侧破坏和随后的皮质失明，仍然可以正确地猜测类型的情绪面部表情正在显示，但不能猜测其他类型的情绪或非情绪刺激。功能性磁共振成像显示，在无意识地处理情绪化表情的过程中，右侧杏仁核被激活。
Destruction of the brain's primary visual areas leads to blindness of cortical origin. Here we report on a subject who, after bilateral destruction of his visual cortices and ensuing cortical blindness, could nevertheless correctly guess the type of emotional facial expression being displayed, but could not guess other types of emotional or non-emotional stimuli. Functional magnetic resonance imaging showed activation of the right amygdala during the unconscious processing of emotionally expressive faces.
