Despite the continuously changing visual inputs caused by eye movements, our perceptual representation of the visual world remains remarkably stable. Visual stability has been a major area of interest within the field of visual neuroscience. The early visual cortical areas are retinotopic-organized, and presumably there is a retinotopic to spatiotopic transformation process that supports the stable representation of the visual world. In this study, we used a cross-saccadic adaptation paradigm to show that both the orientation adaptation and face gender adaptation could still be observed at the same spatiotopic (but different retinotopic) locations even when the adapting stimuli were rendered invisible. These results suggest that awareness of a visual object is not required for its transformation from the retinotopic to the spatiotopic reference frame.
尽管眼球运动导致视觉输入不断变化，但我们对视觉世界的感知表现仍然非常稳定。视觉稳定性一直是视觉神经科学领域的一个主要研究领域。早期的视觉皮层区域是视网膜组织的，并且可能存在从视网膜到空间的转换过程，支持视觉世界的稳定表现。在这项研究中，我们使用了眼跳间适应范式来表明，即使适应刺激变得不可见，在相同的空间位置（但不同的视网膜位置）仍然可以观察到方向适应和面孔性别适应。这些结果表明，不需要意识到视觉对象，其就可以从视网膜参考系转换到空间参考系。
