Sleep deprivation (SD) is a common condition that afflicts many people in modern life. Deficits in daytime performance due to SD are experienced universally. Recent evidence indicates that SD causes impairments in cognitive functions. However, the mechanisms that SD impairs cognitive functions are not clear. This review will focus on the behavioral and neural effects of SD with the aim to elucidate the possible mechanisms of SD-induced deterioration in cognitive functions and to identify…

Sleep, the authors' contemporary culture of sleeplessness, insomnia, sleep needs, the physical cost of inadequate sleep, the psychological cost of sleep deprivation, and the effects of sleep debt on safety are described.

Default Network Response to a Working Memory Challenge after Withdrawal of Continuous Positive Airway Pressure Treatment for Obstructive Sleep Apnea

Results suggest that default network functions are further suspended as a result of a shifting of attention towards a more difficult active task in the context of lowered attentional capacity related to sleepiness.

Sleep duration and self-rated health: the national health interview survey 2008.

Both short and long sleep duration are found to be independently associated with fair/poor SRH, independent of age, sex, race-ethnicity, smoking, alcohol intake, body mass index, physical activity, depression, diabetes mellitus, hypertension, and CVD.

Orexin A attenuates the sleep-promoting effect of adenosine in the lateral hypothalamus of rats

It is found that microinjection of orexin A into the lateral hypothalamus increased wakefulness with a concomitant reduction of sleep during the first 3 h of post-injection recording, and this was completely blocked by a selective antagonist for Orexin receptor 1, SB 334867.

Causes and Consequences of Occupational Fatigue: Meta-Analysis and Systems Model

Although there is a great deal of occupational fatigue literature,there is a dearth of replication and validations studies and researchers are encouraged to address knowledge gaps like the relationship between worker relationships and fatigue.

The Effect of Total Sleep Deprivation on Cognitive Functions in Normal Adult Male Subjects

The results indicate that sleep deprivation has a negative effect on cognitive functions, especially those associated with right anterior hemisphere or subcortical areas, including motor, rhythm, receptive & expressive speech, memory and complex verbal arithmetic function.

Neural basis of alertness and cognitive performance impairments during sleepiness. I. Effects of 24 h of sleep deprivation on waking human regional brain activity

Evidence is provided that short‐term sleep deprivation produces global decreases in brain activity, with larger reductions in activity in the distributed cortico‐thalamic network mediating attention and higher‐order cognitive processes, and is complementary to studies demonstrating deactivation of these cortical regions during NREM and REM sleep.

Less effective executive functioning after one night's sleep deprivation

Following SD, the performance of subjects on an ecologically valid test, the modified Six Elements Test, was significantly impaired and may be of special importance for individuals with cognitive work tasks.

Sleep Deprivation Causes Behavioral, Synaptic, and Membrane Excitability Alterations in Hippocampal Neurons

The exposure of rats to 72 hr of primarily rapid eye movement SD impaired their subsequent performance on a hippocampus-dependent spatial learning task but had no effect on an amygdala-dependent learning task, suggesting that failure to acquire adequate sleep produces several molecular and cellular level alterations that profoundly inhibit hippocampal functioning.

Total sleep deprivation effect on disengagement of spatial attention as assessed by saccadic eye movements

Impairment of error monitoring following sleep deprivation.

The results showed that a vicious cycle occurred between performance deterioration and impairment of error-remedial mechanisms that inevitably led to making more successive errors, which resulted in slower and more varied reaction times, more response errors and omissions, and impaired posterror adjustments to response accuracy.

Auditory Event-Related Potentials and Psychological Changes during Sleep Deprivation

Although the changes in P300 and N200 induced by sleep deprivation are due to sleepiness, which may slow cognitive processing and decrease the efficiency of mental processing, the increase in P200 may be related with increased anxiety, negative mood, and fatigue.

Effects of sleep deprivation on performance and EEG spectral analysis in young adults.

The results show that motor procedural, implicit memory, and working memory are sensitive to one night of TSD, and that Frontal and Temporal theta spectral power seem to discriminate between a night with sleep from a night without.

Identification and differential vulnerability of a neural network in sleep deprivation.

A network whose expression decreased after sleep deprivation and correlated with memory performance was identified and it is concluded that this activation network plays a role in cognitive function during sleep deprivation.
