Dissociable effects of sleep deprivation on functional connectivity in the dorsal and ventral default mode networks.

To examine changes in functional connectivity of the default mode network (DMN) that are induced by sleep deprivation, and to identify individual differences that contribute to the vulnerability of the brain's response to sleep deprivation.

Sleep Deprivation Enhances Inter-Stimulus Interval Effect on Vigilant Attention Performance.

Sleep deprivation significantly reduces the ability to maintain a consistent alertness level and impairs vigilant attention. Previous studies have shown that longer inter-stimulus intervals (ISI) are associated with faster reaction times (RT) on the Psychomotor Vigilance Test (PVT). However, whether and how sleep deprivation interacts with this ISI effect remains unclear.

Effect of sleep deprivation on hearing levels in rats.

To our knowledge, the influence of sleep deprivation on hearing levels has yet to be assessed in animals. Therefore, we evaluated whether auditory function was affected by sleep deprivation in rats.

Neuroendocrine aspects of improving sleep in epilepsy.

Sleep plays an intricate role in epilepsy and can affect the frequency and occurrence of seizures. With nearly 35% of U.S. adults failing to obtain the recommended 7 h of sleep every night, understanding the complex relationship between sleep and epilepsy is of utmost relevance. Sleep deprivation is a common trigger of seizures in many persons with epilepsy and sleep patterns play a role in the occurrence of seizures. Some patients have their first seizure or repeated seizures after an "all-nighter" at co...

Chronic Sleep Deprivation in Mouse Pups by Means of Gentle Handling.

Sleep is critical for proper development and neural plasticity. Moreover, abnormal sleep patterns are characteristic of many neurodevelopmental disorders. Studying how chronic sleep restriction during development can affect adult behavior may add to our understanding of the emergence of behavioral symptoms of neurodevelopmental disorders. While there are many methods that can be used to restrict sleep in rodents including forced locomotion, constant disruption, presentation of an aversive stimulus, or elect...

Sleep pirates-are we really living through a sleep deprivation epidemic and what's stealing our sleep?

Augmentation of Pharmacotherapy by Sleep Deprivation with Sleep Phase Advance in Treatment-Resistant Depression.

The aim was to assess the efficacy of total sleep deprivation (TSD) with sleep phase advance (SPA) in treatment-resistant depression (TRD) and associated biochemical factors.

Increased Vulnerability to Attentional Failure during Acute Sleep Deprivation in Women Depends on Menstrual Phase.

Investigate sex differences in the effect of sleep deprivation on performance, accounting for menstrual phase in women.

The wake maintenance zone shows task dependent changes in cognitive function following one night without sleep.

The interaction between homeostatic sleep pressure and circadian timing modulates the impact of sleep deprivation on cognition. We aimed to investigate how this interaction affects different cognitive functions.

The relationship between naturalistic sleep variation and error monitoring in young adults: An event-related potential (ERP) study.

Sleep deprivation studies have highlighted the importance of adequate sleep for optimal daytime functioning. However, there is limited research exploring whether variations in natural sleep patterns produce similar difficulties to those seen in sleep deprivation studies. The aim of the current study was to explore whether naturalistic reductions in sleep duration and/or sleep quality were associated with behavioural and electrophysiological measures of cognitive control. Sixty undergraduate students were as...

REM deprivation but not sleep fragmentation produces a sex-specific impairment in extinction.

REM sleep is essential for learning and memory processes, particularly emotional learning. Manipulations of REM sleep impair learning and memory and sleep architecture is often altered following a learning experience; for example, short term REM deprivation immediately after fear conditioning results in impaired extinction. In light of research demonstrating sex-dependent differences in fear conditioning as well as differences in sleep architecture, the present study investigated the effects of short term R...

Sleep spindles in adolescence: a comparison across sleep restriction and sleep extension.

The tendency for adolescents to have restricted sleep has been examined in numerous studies; however, the impact of sleep restriction on adolescents' neural activity during sleep (measured by electroencephalography (EEG)) is less extensively researched, particularly regarding sleep spindles.

Sleep deprivation impairs cognitive performance in zebrafish: a matter of fact?

The zebrafish (Danio rerio) has become a valuable model organism for behavioral studies examining learning and memory. Its diurnal circadian rhythm and characterized sleep-like state make it comparable to mammals, features that have contributed to establishing this small vertebrate as a translational model for sleep research. Despite sleep being an evolutionarily conserved behavior, its mechanisms and functions are still debated. Sleep deprivation is commonly associated with decreased attention, reduced res...

Cardiovascular regulation and body temperature: evidence from a nap vs. sleep deprivation randomized controlled trial.

In this study we set out to understand is sleep fragmentation affects the cardiovascular regulation and circadian variability of core body temperature more or less than sleep deprivation. 50 healthy men (age 29.0+/-3.1 years; BMI 24.3+/-2.1 kg/m(2)) participated in a 3-day study that included one adaptative night and one experimental night involving randomization to: sleep deprivation (SD) and sleep fragmentation (SF). The evaluation included hemodynamic parameters, measures of the spectral analysis of hear...

Sleep debt at the community level: impact of age, sex, race/ethnicity and health.

Insufficient sleep has become recognized as a pervasive problem in modern society. Sleep debt is a novel measure of sleep adequacy that may be useful in describing those at risk for inadequate sleep. Our objective was to investigate factors that may be associated with sleep debt at the population level, as well as build upon previous data that showed that minority groups may be more likely to have sleep debt.

Waking up too early - the consequences of preterm birth on sleep development.

Good quality sleep of sufficient duration is vital for optimal physiological function and our health. Sleep deprivation is associated with impaired neurocognitive function and emotional control, and increases the risk for cardiometabolic diseases, obesity and cancer. Sleep develops during fetal life with the emergence of a recognisable pattern of sleep states in the preterm fetus associated with the development, maturation, and connectivity within neural networks in the brain. Despite the physiological impo...

Sleep disturbance and pain: a tale of two common problems.

Chronic pain has been associated with sleep disturbances in a bidirectional manner, with pain disrupting sleep, and sleep deprivation or disturbance increasing pain. This conventional view began to be reassessed with data from longitudinal and micro-longitudinal studies investigating the causal relationship. In this review, we examine the current thinking on the temporal associations between sleep and pain, focusing on studies that considered whether sleep disturbances could predispose individuals to pain c...

The Neurobiological Basis of Sleep and Sleep Disorders.

The functions of sleep remain a mystery. Yet they must be important since sleep is highly conserved, and its chronic disruption is associated with various metabolic, psychiatric, and neurodegenerative disorders. This review will cover our evolving understanding of the mechanisms by which sleep is controlled and the complex relationship between sleep and disease states.

Melatonin for the promotion of sleep in adults in the intensive care unit.

Patients in the intensive care unit (ICU) experience sleep deprivation caused by environmental disruption, such as high noise levels and 24-hour lighting, as well as increased patient care activities and invasive monitoring as part of their care. Sleep deprivation affects physical and psychological health, and patients perceive the quality of their sleep to be poor whilst in the ICU. Artificial lighting during night-time hours in the ICU may contribute to reduced production of melatonin in critically ill pa...

Sustained vigilance is negatively impacted by mild and acute sleep loss reflected by reduced capacity for decision making, motor preparation and execution.

The behavioural and cognitive consequences of severe sleep deprivation are well understood. Surprisingly, relatively little is known about the neural correlates of mild and acute sleep restriction on tasks that require sustained vigilance for prolonged periods of time during the day.

Usage of Therapeutic Sleep Deprivation: A Survey in Psychiatric Hospitals in Austria, Germany, and Switzerland.

Therapeutic sleep deprivation (SD) is a nonpharmacological treatment that is used most often for depression. The aim of this study was to examine the pattern of use of SD in psychiatric hospitals in Austria, Germany, and Switzerland.

Short-term sleep deprivation with exposure to nocturnal light alters mitochondrial bioenergetics in Drosophila.

Many studies have shown the effects of sleep deprivation in several aspects of health and disease. However, little is known about how mitochondrial bioenergetics function is affected under this condition. To clarify this, we developed a simple model of short-term sleep deprivation, in which fruit-flies were submitted to a nocturnal light condition and then mitochondrial parameters were assessed by high resolution respirometry (HRR). Exposure of flies to constant light was able to alter sleep patterns, causi...

Sleep disturbances after deployment: National Guard soldiers' experiences and strategies.

Sleep deprivation and sleep disturbance are pervasive among military personnel during and after combat deployment. However, occupational and other constraints often influence military workers to decline behavioral health services and prescription pharmaceutical sleep aids. This article, drawing on ethnographic interviews with National Guard veterans of combat deployment, demonstrates that soldiers with sleep disturbance frequently manage symptoms without medical supervision and by using ad hoc methods inclu...

Combining trait and state model systems of psychosis: The effect of sleep deprivation on cognitive functions in schizotypal individuals.

Model systems of psychosis play an important role in pathophysiology and drug development research. Schizotypal individuals display similar cognitive impairments as schizophrenia patients in several domains. Therefore, schizotypy may be interpreted as a trait model system of psychosis. In addition, experimentally controlled sleep deprivation is a putative state psychosis model that evokes subclinical psychosis-like states. We aimed to further validate these model systems by examining them in relation to cen...
