"Sleepiness may impair the brain’s inhibitory control when viewing high-calorie foods"

July 25, 2011

An AASM press release announced findings that daytime sleepiness may affect inhibitory control in the brain when viewing high calorie foods.

Principal investigator William Killgore, PhD. of Harvard Medical School and McLean Hospital and his team found that subjects who reported more daytime sleepiness showed decreased activation in the prefrontal cortex during visual presentation of enticing, high-calorie foods. The prefrontal cortex plays an important role in inhibitory processing. Dr. Killgore noted that the rapidly rising rate of obesity makes it important to understand the relationship between sleep-related factors, brain responses to food, and eating behavior.

The findings were presented at the SLEEP 2011 meeting in Minneapolis, MN.
