Stopping the Hermann grid illusion by sine distortion

The usually accepted Baumgartner model cannot explain this phenomenon

The essence of Baumgartner's hypothesis is that the relative increase of lateral
inhibition in receptive fields is sufficient condition of the perception of illusory
spots - it does not refer to any further conditions.

Evidently, considering the left and right sides, the stimulations of the signed
receptive fields are pairwise equivalent.

Consequence...?   See: Wikipedia.org 

Stopping the scintillation

Curving the streets makes both Hermann spots and scintillation vanish. This fact suggests a common neuronal mechanism behind the Hermann grid illusion and the Scintillating grid illusion, whose investigation is a task of the future.
