Daytime Light Exposure Dynamically Enhances Brain Responses
Human Brain Function and Light
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. Now, by exposing subjects to light and imaging their brains while they subsequently perform a cognitive test, researchers have begun to identify brain regions involved in the effects on brain function of daytime light exposure. The findings are reported by Gilles Vandewalle and Pierre Maquet of the University of LiХge, Derk-Jan Dijk of the University of Surrey, and additional colleagues and appear in the August 22nd issue of the journal Current Biology, published by Cell Press.
