Some patients who are considered cortically blind due to the loss of their primary visual cortex (V1) show a remarkable ability to act upon or discriminate between visual stimuli presented to their blind field, without any awareness of those stimuli. This phenomenon is often referred to as blindsight. Despite the range of spared visual abilities, the identification of the pathways mediating blindsight remains an active and contentious topic in the field. In this review, we discuss recent findings of the candidate pathways and their relative contributions to different forms of blindsight across the lifespan to illustrate the varied nature of unconscious visual processing.
一些被认为由于初级视皮层（V1）丧失而皮质盲的患者，在没有任何意识的情况下，对呈现给其视野盲侧的视觉刺激表现出显著的反应或辨别能力。这种现象通常被称为盲视。尽管存在各种保留的视觉能力，但介导盲视的通路的识别仍然是该领域一个活跃且有争议的话题。在这篇综述中，我们讨论了候选通路的最新发现及其对不同形式的盲视在整个生命周期中的相对贡献，以说明无意识视觉处理的多样性。
