Is
the Mona Lisa in Leonardo da Vinci's masterpiece smiling at us when we look at her? For
years, viewers of the painting have been divided
between those who see a little smile and those who
dont. But now Spanish researchers may have solved
the mystery of the Mona Lisa, reports the U.K.'S The
Daily Telegraph
It's not a matter of the painting but the viewer,
they say. Whether we think she is smiling or not
depends upon which cells in the eye catch the image
first and how information from the image moves
through the brain
It's a question of how the eyes and the brain work
Different areas of the eye are responsible for picking
up different information about light and dark colors,
background and foreground. The information takes
different channels through the brain.
Luis Martinez Otero, a Spanish scientist, said in an
interview " Sometimes one channel wins over the other
and you see the smile. Sometimes others take over, and
you don't see the smile
