The Motion Induced Blindness illusion was discovered by Yoram Bonneh. Work by Jack Pettigrew at University of Queensland suggests that this illusion results from a rivalry for dominance between the left and right hemispheres at the parietal lobe. When the right hemisphere is dominant, you see the yellow dots; when left hemisphere gains dominance, the yellow dots disappear. Please try an improved example of the MIB illusion, if you initially had difficulty seeing this effect.
