The putative independence of cortical mechanisms for color, form, and motion raises the binding problem—how is neural activity coordinated to create unified and correctly segmented percepts? Binding could be guided by stimulus-driven correlations between mechanisms, but the nature of these correlations is largely unexplored and no one has (intentionally) studied effects on binding if this joint information is compromised. Here, we develop a theoretical framework which: (1) describes crosstalk-generated correlations between cortical mechanisms for color, achromatic form, and motion, which arise from retinogeniculate encoding; (2) shows how these correlations can facilitate synchronization, segmentation, and binding; (3) provides a basis for understanding perceptual oddities and binding failures that occur for equiluminant and stabilized images. These ideas can be tested by measuring both perceptual events and neural activity while achromatic border contrast or stabilized image velocity is manipulated.
