Why does this illusion work?
(hint: lateral something, explain)
Lateral inhibition:
Regions of retina → 1 views intersection of white horizontal line, 2 views white band between two intersections
Intersection: light coming from all four sides
White band between intersection: surrounded by dark sides
Lateral inhibition causes bright surrounded by dark to appear brighter, dark surrounded by light to appear darker → so depending on what you’re focused on, different dots will appear different colors
