通常认为,通过上级丘和枕到杏仁核的皮层下通路介导了情感性视觉刺激的无意识加工。我们回顾解剖学和生理学的数据,反对这样一个途径在处理人类的情感视觉刺激中起着重要作用的概念。相反,我们提出,杏仁核在视觉处理的主要作用,如枕,是协调功能的皮质网络在评估的生物意义的情感视觉刺激。在这个修正的框架下,大脑皮层在情绪处理中的作用比传统上认为的要重要得多。
A subcortical pathway through the superior colliculus and pulvinar to the amygdala is commonly assumed to mediate the non-conscious processing of affective visual stimuli. We review anatomical and physiological data that argue against the notion that such a pathway plays a prominent part in processing affective visual stimuli in humans. Instead, we propose that the primary role of the amygdala in visual processing, like that of the pulvinar, is to coordinate the function of cortical networks during evaluation of the biological significance of affective visual stimuli. Under this revised framework, the cortex has a more important role in emotion processing than is traditionally assumed.
