Eye Movements and Visual Perception

描述（由申请人提供）：随着眼睛的每一次运动，世界扫过我们的视网膜，并出现在一个新的位置。然而，健康的人通常幸福地不知道这一点，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：大脑是如何将不断变化的视网膜输入转化为对世界的稳定感知的？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，该项目将使用行为学、电生理学和计算方法来研究这个基本问题。该项目的第一个目的是确定眼位置信号在初级视觉皮层的鲁棒性和稳定性。第二个目的是确定这些信号是否与位置感知有因果关系。第三个目标是了解我们眼睛产生的快速运动是如何隐藏在意识之外的，并确定在视觉皮层的哪个部位实现了这一机制。第四个目标是了解快速眼球运动时视觉信息处理发生了什么；是每一次眼球运动都重新开始处理，还是在视觉场景的细节上有信息的转移和整合？

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?
