“…Three American volunteers were subjected to a 90-hour sleep deprivation during which one person experienced hallucinations [11], but it was not until the 1960s that organized series of trials were performed on humans [12,13], yielding sleep deprivation of one week. This type of studies makes it possible to evaluate the influence of progressive sleep loss sound, and low motivation or little interest on the part of the participants [1].…”

“…This type of studies makes it possible to evaluate the influence of progressive sleep loss sound, and low motivation or little interest on the part of the participants [1]. The longest period of sleep deprivation achieved in a human volunteer study lasted 205 hours (8.5 days) [12,13]. During this period, alpha waves were absent in EEG recording, and during the waking state, the EEG signal resembled the 1 NREM stage.…”

This paper presents the history of research and the results of recent studies on the effects of sleep deprivation in animals and humans. Humans can bear several days of continuous sleeplessness, experiencing deterioration in wellbeing and effectiveness; however, also a shorter reduction in the sleep time may lead to deteriorated functioning. Sleeplessness accounts for impaired perception, difficulties in keeping concentration, vision disturbances, slower reactions, as well as the appearance of microepisodes of sleep during wakefulness which lead to lower capabilities and efficiency of task performance and to increased number of errors. Sleep deprivation results in poor memorizing, schematic thinking, which yields wrong decisions, and emotional disturbances such as deteriorated interpersonal responses and increased aggressiveness. The symptoms are accompanied by brain tissue hypometabolism, particularly in the thalamus, prefrontal, frontal and occipital cortex and motor speech centres. Sleep deficiency intensifies muscle tonus and coexisting tremor, speech performance becomes monotonous and unclear, and sensitivity to pain is higher. Sleeplessness also relates to the changes in the immune response and the pattern of hormonal secretion, of the growth hormone in particular. The risk of obesity, diabetes and cardiovascular disease increases. The impairment of performance which is caused by 20-25 hours of sleeplessness is comparable to that after ethanol intoxication at the level of 0.10% blood alcohol concentration. The consequences of chronic sleep reduction or a shallow sleep repeated for several days tend to accumulate and resemble the effects of acute sleep deprivation lasting several dozen hours. At work, such effects hinder proper performance of many essential tasks and in extreme situations (machine operation or vehicle driving), sleep loss may be hazardous to the worker and his/her environment.

“…It also reduces inhibition of basal forebrain ACh by Ad, increasing the firing rate of ACh nuclei [42], and the value of A in equation (2.2). These effects are modelled by the replacements [38]. Simulated wake effort W over the same period is rescaled by a constant factor to reproduce the observations.…”

Arousal is largely controlled by the ascending arousal system of the hypothalamus and brainstem, which projects to the corticothalamic system responsible for electroencephalographic (EEG) signatures of sleep. Quantitative physiologically based modelling of brainstem dynamics theory is described here, using realistic parameters, and links to EEG are outlined. Verification against a wide range of experimental data is described, including arousal dynamics under normal conditions, sleep deprivation, stimuli, stimulants and jetlag, plus key features of wake and sleep EEGs.
