Development of Sensory and Motor Binocularity

为了有效的人类视觉，大脑必须整合来自两只眼睛的双目输入，并反过来驱动两只眼睛朝着适当的方向移动。感觉双视性的发展似乎依赖于两只眼睛对齐以对每只眼睛视网膜上对应的点进行视觉刺激的能力。这种排列是视觉皮质中对视网膜视差和立体视觉敏感的细胞发育的先兆。这个项目研究了眼球运动和感觉因素如何结合在一起，对人类婴儿期双眼视觉功能的发展做出贡献。概述了可能的发育关系的模型，并将使用一种新的双目眼睛跟踪技术来测量人类婴儿的眼睛运动。通过各种行为和非侵入性测试，将有关发育运动双目的数据与发育的感觉双视的数据进行比较，以了解感觉和运动因素是如何结合的。这项研究的结果将对视觉科学、发育性人类研究和人类行为分析具有重要意义，对理解双眼视觉障碍可能更重要。***

For effective human vision, the brain must integrate the binocular input from the two eyes, and in turn drive the two eyes to move binocularly in appropriate directions. The development of sensory binocularity appears to depend on the ability to align the two eyes to give visual stimulation of corresponding points on the retina of each eye. This alignment is a precursor to development of cells in the visual cortex that are sensitive to retinal disparity, and for stereoscopic vision. This project studies how oculomotor and sensory factors combine to contribute to the development of binocular visual functions during infancy in humans. Models are outlined for possible developmental relationships, and a novel binocular eye-tracking technique will be used to measure human infant eye movements. Data on developing motor binocularity is compared to data on developing sensory binocularity measured by a variety of behavioral and non-invasive tests, to see how sensory and motor factors are combined. Results from this study will be important to visual science, and also to developmental human research and to human performance analysis, with further likely importance to understanding disorders in binocular vision. ***
