Sleep Deprivation

The American Journal of Gastroenterology is published by Nature Publishing Group (NPG) on behalf of the American College of Gastroenterology (ACG). Ranked the #1 clinical journal covering gastroenterology and hepatology*, The American Journal of Gastroenterology (AJG) provides practical and professional support for clinicians dealing with the gastroenterological disorders seen most often in patients. Published with practicing clinicians in mind, the journal aims to be easily accessible, organizing its con

It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD) pathophysiology may overlap with those involved in humor appreciation. However, to date, there have been no studies that have explored humor appreciation in OCD. The purpose of the present work was to investigate humor appreciation in a group of patients with OCD.|It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD) pathophysiology may ov

The article presents the results of oculomotor reaction investigations during 24-hour sleep deprivation of 10 normal male subjects aged 25 to 30 yrs. Video nistagmograph VNG System VO-25 was used for binocular registration of eye movements. The proposed video procedures for assessment of the functional ability of human operator are a balancing test, investigation of saccadic and smooth tracking eye movements. The balancing test is designed to determine the nystagmic activity, the saccade test, latency, peak velocity and precision of saccades, and the smooth tracking test, standard errors in tracking velocity and displacement In addition to video oculography, velocity of a simple sensorimotor reaction was measured and the self-rating scale of well-being, alertness and mood (SAN) was employed. The balancing test showed balancing nystagmus; occurrence of this nystagmus grew high with desynchronosis. Saccades registered during sleep deprivation pointed to a considerable decline of velocity

To investigate whether there are any objective EEG characteristics that change significantly between specific time periods during maintenance of wakefulness test (MWT) and whether such changes are associated with the ability to appropriately communicate sleepiness.|After a night of total sleep deprivation, 12 healthy young subjects underwent a MWT whilst being instructed to communicate the experience of subjective sleepiness by pressing a button. EEG analysis consisted of average relative power and correlation between EEG signals.|A comparison of the 30 s before microsleep (MS) with 30 s before subjects communicated experience of sleepiness (PB) showed increased correlation as well as increased power in the band (13-20 Hz) whereas power in the (4.5-7.5 Hz) and (8-12.5 Hz) band was significantly decreased. When subjects later failed to communicate the experience of subjective sleepiness before (micro-)sleep occurred, average relative power and EEG correlation were

During the adolescent years, a delayed pattern of the sleep-wake cycle occurs. Many parents and health care providers are not aware that once established, these poor sleep habits can continue into adulthood. Early school hours start a pattern of sleep loss that begins a cycle of daytime sleepiness, which may affect mood, behavior, and increase risk for accidents or injury. These sleep-deprived habits established in adolescence can often lead to problems during college years. Sleep hygiene can be initiated to help break the cycle, along with education and implementation of a strict regimen. Monitoring all adolescents and college-aged students for sleep insufficiency is imperative to improve both academic and emotional well-being.

The effect of sleep deprivation by 'carousel' method on spatial memory consolidation in a Morris water maze was studied in Wistar male rats after one-day learning (in accordance to a protocol by Frick et al., 2000). It was found that after fast 3-hr learning the memory trace retains during 24-hr. Twenty four hour sleep deprivation followed learning impaired consolidation of spatial memory. So the rat model of a one-day learning is suitable for the studying of neurophysiological mechanisms of sleep deprivation effects on spatial memory consolidation.
