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.

盲视与年龄相关的神经基质

一些由于初级视觉皮层 (V1) 丧失而被认为是皮质失明的患者表现出非凡的能力，可以对呈现给他们盲区的视觉刺激采取行动或区分这些刺激，而对这些刺激没有任何意识。这种现象通常被称为盲视。尽管有多种视觉能力，但确定介导盲视的途径仍然是该领域一个活跃且有争议的话题。在这篇综述中，我们讨论了候选途径的最新发现及其对整个生命周期中不同形式的盲视的相对贡献，以说明无意识视觉处理的不同性质。
