DESCRIPTION (provided by applicant): With every eye movement, the world sweeps across our retina and appears in a new position. Healthy humans, however, usually remain blissfully unaware of this, and perceive the world as stable. The long term goal of this project is to answer the fundamental unsolved question: how does the brain transform the ever-changing retinal input into a stable percept of the world? To further the mission of the National Eye Institute to research the mechanisms of visual function, the project will investigate this fundamental question using behavioral, electrophysiological, and computational methods. The first aim of the project is to determine the robustness and stability of eye position signals in primary visual cortex. The second aim is to determine whether these signals are causally related to the perception of position. The third aim is to understand how the rapid movements created by our eyes are hidden from awareness, and to determine where in visual cortex this mechanism is implemented. The fourth aim is to understand what happens to visual information processing at the time of a rapid eye movement; does processing start anew with every eye movement, or is there transfer and integration of the information on the details of the visual scene?

描述（由申请人提供）：随着每一次眼球运动，世界扫过我们的视网膜，并出现在一个新的位置。然而，健康的人类通常对此保持幸福的意识，并认为世界是稳定的。这个项目的长期目标是回答一个基本的未解决的问题：大脑如何将不断变化的视网膜输入转化为对世界的稳定感知？为了进一步完成国家眼科研究所研究视觉功能机制的使命，该项目将使用行为、电生理和计算方法研究这一基本问题。该项目的第一个目的是确定初级视觉皮层中眼位置信号的鲁棒性和稳定性。第二个目的是确定这些信号是否与位置感知有因果关系。第三个目的是了解我们的眼睛创造的快速运动是如何隐藏在意识之外的，并确定这种机制在视觉皮层中的位置。第四个目标是了解在快速眼动时视觉信息处理发生了什么;处理是否随着每次眼动而重新开始，或者是否存在视觉场景细节信息的转移和整合？
