Dynamic transitions of blind spots in the Hermann grid illusion
Abstract
Hermann discovered the grid illusion in 1870, but its cause has remained a mystery for more than 150 years. In 1960, Baumgartner proposed a hypothesis for the illusion based on neural receptive fields, but Geier presented a counterexample in 2008. In 1995, Schrauf devised the scintillating grid illusion, an improvement on the Hermann grid illusion. I propose that a hypothesis involving blind spots (optic discs) can significantly contribute to unraveling the mystery of the grid illusion.
