项目摘要

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）：随着每一次眼睛的移动，世界都遍及我们的视网膜，并出现在新的位置。然而，健康的人类通常仍然没有意识到这一点，并认为世界是稳定的。该项目的长期目标是回答基本未解决的问题：大脑如何将不断变化的视网膜输入转化为对世界稳定的感知？为了进一步研究视觉功能的机制，该项目将使用行为，电生理和计算方法研究这个基本问题。该项目的第一个目的是确定初级视觉皮层中眼睛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眼睛所产生的快速运动如何隐藏在意识上，并确定在视觉皮层中实现这种机制。第四个目的是了解快速眼动时视觉信息处理会发生什么；处理是否会随着每一个眼动的方式重新开始，还是在视觉场景的详细信息上传输和集成信息？
