    New research shows that pupils dilate and constrict in response to imagined light and dark scenarios in a similar way as results from actual perception.

    Animals automatically constrict and dilate their pupils in response to light.  But a new study out of Norway reveals that even just imaging abright or dimly lit scenario can cause your eyes to react.  Talk about the power of the mind!  In experiments, participants pupils dilated when imagining bright shapes and constricted when imagining dark shapes.  And the same effect occurred when they imagined a bright room and dark room. Researchers said “the presence of pupillary adjustments to imaginary light presents a strong case for mental imagery as a process based on brain states similar to those which arise during actual perception.” And presents another strong case for the statement “you imagine the world you play in.”
