In this study we used RIFT and MEG to track visual-cortical excitability during perceptual filling-in and found that the signal increased just before the illusion emerged. This showed that filling-in is preceded by changes in early visual cortex, but not by the low-level spreading predicted by isomorphic accounts. Instead, the results support a hierarchical visuo-motor process underlying the perceptual transition.
