Research has found that together, attention and sleep deprivation modulate the parahippocampal place area (PPA) activation and scene processing. Specifically, sleep deprivation was related to significant decreases in PPA activation while attending to scenes and when ignoring scenes.
Sleep deprivation has become hardwired into the military culture. It is prevalent in the entire force and especially severe for servicemembers deployed in high-conflict environments. [188] [189] Sleep deprivation has been used by the military in training programs to prepare personnel for combat experiences when proper sleep schedules are not ...
Shows convergent validity with other symptom scales such as ESS and Karolinska Sleepiness Scale, [6] prediction of performance after sleep deprivation [4] Discriminative validity: Adequate: Studies do not report AUCs, some mention overlap between sleepiness, physical tiredness, and depression [4] Validity generalization: Good
Sleep and weight is the association between the amount of sleep an individual obtains and the weight of that individual.. Numerous studies have demonstrated an association between sleep disturbances and weight gain, and more specifically, that sleep deprivation is related to overweight. [1]
Sleep deprivation has been found to affect mood as well. [47] This effect is most pronounced in those that are consistently partially sleep deprived, which is the case for many college students. A meta-analysis of several studies regarding sleep deprivation suggests that the effects of partial sleep deprivation are underestimated.
Physiologist Ancel Keys was the lead investigator of the Minnesota Starvation Experiment. He was directly responsible for the X-ray analysis and administrative work and the general supervision of the activities in the Laboratory of Physiological Hygiene which he had founded at the University of Minnesota in 1940 after leaving positions at Harvard's Fatigue Laboratory and the Mayo Clinic.
Sleep deprivation slows the generation of facial reactions in response to emotional faces. [15] One to two nights of sleep loss in healthy adults is associated with a decrease in the generated intensity of positive moods (i.e. happiness and activation), as well as an increase in the generated intensity of negative moods (i.e. anger , depression ...
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
