Following damage to primary visual cortex, some patients our initial findings. The data reveal a patchy distribution of redemonstrate a limited ability to respond to stimuli they do not sidual visual abilities in the absence of acknowledged awareness. acknowledge seeing. This residual vision, which has been referred to as "blindsight," has been attributed to secondary visual pathways. We previously reported an isolated island of blindsight in one patient and argued it was a likely consequence of cortical sparing in V1. We now report an extension of our initial findings. The data reveal a patchy distribution of residual visual abilities in the absence of acknowledged awareness. Variable patterns of cortical sparing appear to be the most parsimonious way to account for this outcome, suggesting that blindsight is generally mediated by the primary visual pathway.
在初级视皮层受损后，我们的初步发现表明，一些患者表现出有限的对刺激做出反应的能力，而这些刺激是他们没有意识到的。这种残留的视觉能力，以前被称为“盲视”，归因于次级视觉通路。我们之前报道了一名患者存在孤立的盲视岛，并认为这很可能是 V1 皮质保留的结果。现在，我们报告了初始发现的扩展。数据显示，在没有意识承认的情况下，残留的视觉能力呈斑片状分布。皮质保留的可变模式似乎是解释这种结果的最合理方式，这表明盲视通常是由初级视觉通路介导的。
