Neuroimaging studies of human binocular vision and stimulus selection

正常的视力需要两只眼睛的信息结合。在大多数情况下，当来自两只眼睛的信息与空间中的单个物体兼容时，可以提取深度信息。在两眼信息不相容的情况下，就会产生一种竞争的感觉。为了全面了解大脑功能，特别是双眼视觉，了解深度和竞争背后的过程之间的关系是至关重要的。我们的长期目标是提供双眼组合的感知和生理解释，将我们对整个视觉系统的理解整合在一起。本应用程序的目的是更好地表征人类大脑中的网络组织，这是双眼深度和竞争感知的基础，包括与单眼竞争和双视遮蔽的比较。我们提出，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，我们可以评估双目视觉的竞争理论，并将我们的发现与当前对感知意识的理解联系起来。

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.
