Abstract: International audience; When an obliquely moving sine wave grating is presented inside a square aperture, observers are faced with a conflict of local motion signals resulting from the "aperture problem". Motion signals along the grating contours on average have a diagonal direction (D) while those near the horizontal (H) and vertical (V) edges lie along these cardinal directions. We explored the temporal evolution of this perception, which shifts regularly between the cardinal directions H and V as the dominant neural population serving consci...
