When sleep-deprived, PCC activity decreases, impairing selective attention. Subjects were exposed to an attention-shifting task involving spatially informative, misleading and uninformative cues preceding the stimuli. When sleep-deprived, subjects showed increased activation in the left intraparietal sulcus. This region is activated when ...
The MCTQ samples sleep and circadian rhythm data from more than 25,000 participants. [ 1 ] Questions about work day and free day sleep schedules, work details, and lifestyle provide data to aid in the understanding of how biological clocks work in social life, such as Roenneberg's conclusions of social jetlag.

[5] [13] The somnolent information processing theory postulates the existence of a sleep onset control system that evolved to ensure that falling asleep tends to happen when it is evolutionarily opportune (safe, timely) to fall asleep.

Sleep deprivation was also found to increase beliefs of being correct, especially if they were wrong. Another study reported that the performance on free recall of a list of nouns is significantly worse when sleep deprived (an average of 2.8 ± 2 words) compared to having a normal night of sleep (4.7 ± 4 words).
Deficient sleep patterns are prominent in many psychiatric ailments. [18] Insomnia increases the risk of a depressive episode, sleep deprivation influences the onset of hypomania, and sleep disturbance contributes to the maintenance of mood disorders. [19] Amongst manic bipolar patients, sleep loss may act as a trigger in the onset of a manic ...
Consisting of 19 items, the PSQI measures several different aspects of sleep, offering seven component scores and one composite score. The component scores consist of subjective sleep quality, sleep latency (i.e., how long it takes to fall asleep), sleep duration, habitual sleep efficiency (i.e., the percentage of time in bed that one is asleep), sleep disturbances, use of sleeping medication ...
