The first sleep phase—nonrapid-eye-movement sleep (NREM sleep)—is characterized by a shift in the electroencephalogram (EEG) in the form of a slowing of the rhythm of oscillations of the potential. In man, a regular succession of changes in physiological parameters permit four stages to be...
It is best to start and continue as long as possible with small doses of the weakest hypnotics. Individual techniques for falling asleep should be devised. Narcolepsy is treated with preparations that stimulate brain activity, and the principal means of treating pickwickian syndrome is by losing ...
This disruption results from irregular sleep and wake times, shortened sleep periods, and misaligned light exposure and food intake, among other factors [2]. This can lead to circadian misalignment, which may negatively impact shiftworkers’ health, wellbeing, productivity, and safety [3, 4], ...
This cohort study evaluates sleep, well-being, and cognition between interns working irregular, extended shifts and those working a more regular schedule
Irregular sleep or insomnia can induce various diseases including cardiovascular disease, cancer, and psychiatric disorders [88,89]. Sleep can also influence the immune system [90]: slow-wave sleep promotes memory consolidation not only in the brain but also in the immune system. For example, ...
During waking, there is regular high-frequency firing. During slow wave sleep (sleep), the firing frequency decreases and becomes irregular. During REM sleep (S-LVF), high frequency bursts of discharges alternate with long silences. Reprinted from Evarts (1964). Journal of Neurophysiology, with...
Sleep is essential but places animals at risk. Filtering acoustic information according to its relevance, a process generally known as sensory gating, is crucial during sleep to ensure a balance between rest and danger detection. The mechanisms of this s
Res~irationof rem mature infants has been described as irregular '2 in AS and more or less regular in QS (8, 17). Respiratory frequency (RF) of prematures has been studied more recently. The age groups, the criteria of a normality and the method of sleep state definition differs from ...
12 mg/kg.Even after high doses of atropine sulphate about 40% of the sleep EEG activity is covered by sleep cycles (regular alternation of generalized slow wave activity with neocortical desynchronization combined with hippocampal theta activity) not differing from normal cycles significantly, the ...
