Effects of Chronic Sleep Deprivation on Sustained Attention: A Study of Dynamic Brain Functional Connectivity According to a survey conducted in 2007, 35-40% of adult U.S population

According to a survey conducted in 2007, 35-40% of adult U.S population chronically restricts their sleep on less than 7 hours on weekday nights, compared with 8-9 hours to maintain brain normal function during the day. Studies have demonstrated that sleep deprivation reduces the capabilities and efficiency of performance by impairing perception, increasing effort to keep concentrate, as well as introducing vision disturbance. In this way, sleep deprivation has been identified as a vital factor in many accidents in transportation and industrial settings. It has been usually recognized that performance decrements after sleep loss are mainly due to attentional deficits. Given the adverse effects of sleep deprivation, researchers have paid increasing attention to investigate the brain activity during attention tasks after insufficient sleep. However, the mechanism of how sleep deprivation impacts human attention has not been fully understood.
