An article in Medical News Today: Blinking Causes Brain to go Off-Line states, "New research from Japan suggests that blinking does more than stop our eyes from drying out:  it is an active process that causes the brain to go off-line, into a more reflective mode, before giving renewed attention."  The article goes on to explain that "the study appears to support the idea that temporarily shutting off sensory inputs helps the brain fine-tune the senses and control the flow of cognitive processes.  This coincides with work by other researchers, such as that of cognitive neuroscientist Daniel Smilek, of the University of Waterloo in Canada, who suggests eye blinking is a sign of mind-wandering."

Blinking causes the brain to go off-line

It continues to be well documented, that eye blinking is related to processing emotion.  In a sense, opening up the "files" on the neural pathways, where it is stored how our experiences have been stored as truth.
