讲座内容:

Human typically spends around one-third of their lives sleeping. Obtaining sufficient sleep is essential for optimal brain and behavioral functioning. However, millions of people, including many students, frequently reduce their sleep time due to work demands, leisure time, and family obligations. Sleep loss has been shown to increase fatigue and sleep propensity, reduce alertness and vigilance, slow psychomotor and cognitive speed, promote wake state instability, and cause considerable social, financial and health-related costs. A recent evidence-based consensus recommendation for the amount of sleep needed to promote optimal health in adults concluded that sleeping less than 7 hours/night (especially ≤6h) was associated with impaired performance, greater risk of accidents, and adverse health outcomes, including obesity, diabetes, hypertension, heart disease, stroke, depression, impaired immune function, increased pain, and risk of death. Although the negative effects of sleep loss on human behavior have been studied for more than a century, how sleep deprivation impairs human brain remains unclear. Here we used multimodal neuroimaging approach to examine the detrimental effects of sleep deprivation on human brain activity and connectivity as well as the relationships between brain deficits, fatigue, and other behavior dysfunction after sleep loss.
