The hermann grid illusion involves the perception of gray dots at the intersections of white lines outside of the fovea the traditional baumgartner model explains this based on the activity of on-center ganglion cells, but as jános geier points out this explanation is insufficient he has shown that the illusion can be eliminated by simply.

An optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that the hermann grid illusion and mach bands are two illusions that are best explained using a biological approach. 1 introduction the hermann grid illusion (1870) in its best-known form consists of intersecting vertical and horizontal white bars superimposed on a black background, thereby forming an.

Making sense of the hermann grid illusion when viewing the hermann grid, you will probably notice the faint dark spots that appear at the intersections of the white lines. The hermann grid illusion consists of smudges perceived at the intersections of a white grid presented on a black background in 1960 the effect was first explained by a theory advanced by baumgartner suggesting the illusory effect is due to differences in the discharge characteristics of retinal ganglion cells when their receptive fields fall. Schiller, ph carvey, ce, 2005: the hermann grid illusion revisited. The difference between the hermann grid illusion and the scintillating illusion is that scintillating illusions have dots already in place at the intersection the hermann grid illusion revisited perception 34 (11): 1375-1397.
