Normal vision requires the combination of information from the two eyes. In most situations where the information from the two eyes is compatible with a single object in space, depth information can be extracted. In circumstances where the information from the two eyes is incompatible, a sensation of rivalry results. To fully understand brain function in general, and binocular vision in particular, it is crucial to know the relationship between the processes underlying depth and rivalry. Our long-term goal is to provide a perceptual and physiological account of binocular combination that integrates with our understanding of the visual system as whole. The objective of this application is to better characterize the network organization in the human brain that underlies the perception of binocular depth and rivalry, including comparison with monocular rivalry and dichoptic masking. We propose that by correlating performance of these visual functions with high-resolution neuroimaging of brain activity we can evaluate competing theories of binocular vision, and relate our findings to current understanding of perceptual awareness.

正常的视觉需要两眼信息的结合。在来自两只眼睛的信息与空间中的单个对象兼容的大多数情况下，可以提取深度信息。 当两只眼睛的信息不一致时，就会产生竞争的感觉。为了全面了解大脑的功能，特别是双眼视觉，了解深度和竞争背后的过程之间的关系至关重要。我们的长期目标是提供一个知觉和生理帐户的双目结合，结合我们的理解，作为一个整体的视觉系统。本申请的目的是更好地表征人类大脑中的网络组织，该网络组织是双眼深度和竞争感知的基础，包括与单眼竞争和双视掩蔽的比较。我们建议，通过将这些视觉功能的表现与大脑活动的高分辨率神经成像相关联，我们可以评估双眼视觉的竞争理论，并将我们的研究结果与当前对感知意识的理解联系起来。
