Synopsis

Analyzing ground-breaking research, this reference highlights the impact of sleep deprivation on the well-being of the individual and society-presenting current theories on the function of sleep, the effects of sleep deprivation on patients with medical and psychiatric conditions, as well as providing interpretative and methodological results in comparative studies of sleep deprivation.

Excerpt

“The term 'function' in the biological literature is a slippery idea. Whether we think in terms of genes, cells or organisms, these entities are not functionally discrete. Despite their differences, each operates seamlessly within a system to achieve survival in the face of environmental challenges, while also carrying the constraints of the evolutionary past and the capacity of future change.”

What is sleep? Sleep scientists might define sleep as a period of behavioral quiescence and non-responsiveness to the environment that is electroencephalographically, physiologically, and behaviorally distinct from the waking state. Sleep is divided into two states, rapid-eye-movement (REM, or “paradoxical” sleep in animals) and non-REM (NREM) sleep that are also electroencephalographically, physiologically, and behaviorally distinct from one another. NREM sleep is further subdivided into four stages 1-4 (or I-IV), corresponding to the depth of sleep, and the presence of specific electrophysiologic markers.

What is sleep deprivation? The deprivation of sleep is the partial or near-complete removal of sleep in an organism. There can never be a complete absence of sleep, due to the fact a “perfect” sleep deprivation procedure has not been developed that is technologically capable of eliminating all sleep. With sleep dep . . .
