Due to the virtual complete decussation of the optic nerves, a right eye superiority is probably related to a left hemisphere dominance. If visual processes between the hemispheres differ, each half-brain might be differently prone to be deceived by visual illusions. Indeed pigeons tested with the herringbone illusions are deceived to a stronger extent with the… CONTINUE READING
