Title:

Neuroimaging Of Sleep Deprivation: How Sleep Loss Affects Brain And Behavior

Abstract:

Insufficient sleep has multiple etiologies and is pervasive in contemporary societies. It is estimated that about 20% to 40% of the United States adults sleep less than 7 hours per night, which is the minimum sleep duration to prevent cumulative deterioration in cognitive performance. Sleep loss not only impairs cognition and behavior, but also increases the risk for multiple diseases including obesity, diabetes, depression, and prospective mortality. Specific neurocognitive domains affected by sleep deprivation include attention, memory and executive functions. In this seminar, Dr. Rao will present some new findings from his multimodal brain imaging studies and other groups about the detrimental effects of sleep deprivation on brain function and behavior.
