The Hermann Grid Illusion: A Tool for Studying Human Perceptive Field Organization
- L. Spillmann
- 1 June 1994
The Hermann grid illusion is weakened when the grid is presented diagonally, which suggests a contribution by the orientation-sensitive cells in the lateral geniculate nucleus and visual cortex, and is consistent with the reduction of the center—surround antagonism in retinal receptive fields.

Thatcher Illusion: Dependence on Angle of Rotation
The sudden nature and relatively narrow zone of the changeover suggest a neuronal step-tuning of hypothetical face cells in the human brain, underlying the holistic (‘grotesque’) versus componential (“pleasant”) processing of upright versus upside-down faces.

The Neon Color Effect in the Ehrenstein Illusion
Van Tuijl's neon color effect arises in the Ehrenstein figure if a colored cross is added such as to connect the black arms across the central gap and has the same hue as the inducing cross.

It is concluded that the visual system does not passively remember perceptual state: it analyzes recent perceptual history and attempts to predict what will come next, which can alter what is seen.
