<p>reality through both perceptual and cognitive neural pathways. Visual illusions are (at least in part) thought to be caused by excessive competing stimuli. Each stimulus follows a dedicated neural path in the early stages of visual processing, and intense/repetitive activity or interaction with active adjoining channels (perceptual neural circuits, usually at the same level) causes a <a href="page.php?w=physiological">physiological</a> imbalance that alters perception. During low-level visual processing, the retinal circuit arranges the information</p><p>
