The surface area of human primary visual cortex (V1) varies substantially between individuals for unknown reasons. We found that this variability was strongly and negatively correlated with the magnitude of two common visual illusions, where two physically identical objects appear different in size as a result of their context. Because such illusions dissociate conscious perception from physical stimulation, our findings indicate that the surface area of V1 predicts variability in conscious experience.
人类初级视觉皮层（V1）的表面积因人而异，原因不明。我们发现，这种可变性与两种常见视觉错觉的程度呈强烈负相关，这两种视觉错觉是指由于所处环境的不同，两个物理上完全相同的物体看起来大小不同。由于这些错觉将有意识的感知与物理刺激分离开来，因此我们的发现表明，V1 的表面积可以预测有意识体验的可变性。
