abstract：:Although luminance and color are thought to be processed independently at early stages of visual processing, there is evidence that they interact at later stages. For example, chromatic information has been shown to enhance or suppress depth from luminance depending on whether chromatic edges are aligned or orthogonal...

abstract：:In retinotopically organized areas of the macaque visual cortex, neurons have been found that shift their receptive fields before a saccade to their postsaccadic position. This saccadic remapping has been interpreted as a mechanism contributing to perceptual stability of space across eye movements. So far, there is on...
