Sleep deprivation has adverse consequences for a variety of cognitive functions. The exact effects of sleep deprivation, though, are dependent upon the cognitive process examined. Within working memory, for example, some component processes are more vulnerable to sleep deprivation than others. Additionally, the differential impacts on cognition of different types of sleep deprivation have not b...

Prospective research indicates sleep deprivation potentiates anxiety development, yet relatively little research has examined the effects of sleep deprivation in terms of specific types of anxiety. The current study tested the association between acute sleep deprivation and panic-relevant biological challenge responding among nonclinical participants. One hundred and two participants were rando...

Many studies have investigated factors that affect susceptibility to false memories. However, few have investigated the role of sleep deprivation in the formation of false memories, despite overwhelming evidence that sleep deprivation impairs cognitive function. We examined the relationship between self-reported sleep duration and false memories and the effect of 24 hr of total sleep deprivatio...

Sleep deprivation alters food consumption in animals; however, little is known of the effects of partial sleep deprivation on food consumption and choice in humans. We examined 50 undergraduate students who recorded sleep quality, food consumption, and food choice in daily diaries for four days. On the second night of the study, participants were instructed to sleep for 4 h or less, which serve...

STUDY OBJECTIVES Sleep deprivation negatively affects memory consolidation, especially in the case of hippocampus-dependent memories. Studies in rodents have shown that 5 hours of sleep deprivation immediately following footshock exposure selectively impairs the formation of a contextual fear memory. In these studies, both acquisition and subsequent sleep deprivation were performed in the anima...

BACKGROUND AND METHODS This study investigated the effects of sleep deprivation on total and partial (early and late) declarative memory and activation in the areas of the brain involved in these activities. The study included two experiments. Experiment 1 included 40 male residents of an orphanage aged 16-19 years, who were divided into four groups (n = 10 each) and subjected to total sleep de...

Effects of sleep deprivation and season on thermoregulation during 60 min. of leg-bathing (water temperature of 42 degrees C, air temperature of 30 degrees C, and relative humidity of 70%) were studied in eight men who completed all 4 experiments for normal sleep and sleep deprivation in summer and winter. Rectal temperature (T(re)), skin temperature, total body sweating rate (M(sw-t)), local s...

The sleeping brain differs from the waking brain in its electrophysiological and molecular properties, including the expression of growth factors and immediate early genes (IEG). Sleep architecture and homeostatic regulation of sleep in neonates is distinct from that of adults. Hence, the present study addressed the question whether the unique homeostatic response to sleep deprivation in neonat...

Sleep deprivation is a common problem of considerable health and economic impact in today's society. Sleep loss is associated with deleterious effects on cognitive functions such as memory and has a high comorbidity with many neurodegenerative and neuropsychiatric disorders. Therefore, it is crucial to understand the molecular basis of the effect of sleep deprivation in the brain. In this study...

STUDY OBJECTIVES Sleep deprivation is believed to worsen obstructive sleep apnea (OSA). We assessed the effect of acute sleep deprivation on polysomnography in a cohort of subjects with mild OSA and a cohort of subjects without OSA. DESIGN Crossover study in which subjects initially had polysomnography after a normal night's sleep or after 36 hours of sleep deprivation, followed by a 2- to 4-...
