White's illusion

White's illusion is a brightness illusion where certain stripes of a black and white grating is partially replaced by a gray rectangle (Fig. 1). Both of the gray bars of A and B are the same color and opacity. The brightness of the gray pieces appear to shift toward the brightness of the top and bottom bordering stripes. This is in apparent opposition to lateral inhibition as it cannot explain this occurrence. This occurs even when the gray patches in the black stripes are bordered by more white than black (and conversely for the gray patches in the white stripes).〔Anderson, L Barton (2003). Perceptual organization and White's Illusion. ''Perception'', 32, 269-284. (). Retrieved 15 February 2015.〕 A similar illusion occurs when the horizontal strips have different colors; this is known as Munker-White's illusion or Munker's illusion.
==Lateral inhibition==
(詳細はbipolar cell response depends on the amount of the stimulation it receives from the receptor and the amount that this response is decreased by the lateral inhibition it receives from its neighboring cells.〔Sensation and perception, E. Bruce Goldstein, Edition 8, illustrated,Publisher Cengage Learning, 2009〕
Lateral inhibition cannot explain White's illusion.〔 In Figure 2.1 lateral inhibition sent by black cells A and C should make cell O lighter; in Figure 2.2 lateral inhibition sent by white cells A and C should make cell O darker. It is suggested that brightness induction follows the brightness contrast in the direction of the bar not the surrounding area.
