Physiological illusions, such as the afterimages following bright lights, or viewing stimuli of alternating patterns are presumed to be the effects on the eyes or brain of excessive stimulation of a specific type – brightness, tilt, color, movement, and so on. Theory suggests that stimuli have individual neural paths at various stages of visual processing, and that repetitive stimulation may causes a physiological imbalance that alters perception.
