Complex visual stimuli evoke diverse patterns of gaze, but previous research suggests that their neural representations are shared across brains. Here, we used hyperalignment to compare visual responses between observers viewing identical stimuli. We find that individual eye movements enhance cortical visual responses but also lead to representational divergence. Pairwise differences in the spatial distribution of gaze and in semantic salience predict pairwise representational divergence in V1 and inferior temporal cortex, respectively. This suggests that individual gaze sculpts individual visual worlds.
复杂的视觉刺激会引发各种不同的注视模式，但之前的研究表明，它们的神经表现形式在不同大脑之间是共享的。在这里，我们使用超对齐来比较观看相同刺激的观察者之间的视觉反应。我们发现，个体的眼球运动增强了皮质视觉反应，但也导致了表现形式的发散。注视的空间分布和语义显著性的成对差异分别预测了 V1 和下颞叶皮层的成对表现形式的发散。这表明，个体的注视塑造了个体的视觉世界。
