NAME

Circadian rhythms and sleep

DESCRIPTION

Circadian rhythms are the regular, daily cycles of biological processes or activities, including the regular and predictable variation in the levels of many circulating hormones, ions and the control of sleep and wakefulness. Circadian rhythms are controlled centrally by the suprachiasmatic nucleus, and are most strongly infuenced by light.

161 skos:definition Non-REM sleep refers to the stages of sleep in which there is little or no random eye movements (REM), that is, stages 1–3 of sleep. During these phases, muscle tone is retained and dreaming is rare; stage 3, the deepest sleep stage, has been associated with memory consolidation.

170 skos:definition Orexin (also known as hypercretin) is a neuropeptide hormone produced in the hypothalamus. It influences sleep and arousal, appetite and energy expenditure, and defective orexin signalling is associated with narcolepsy.

184 skos:definition REM sleep (random eye movement sleep) is the fourth stage of sleep in which the eyes can be seen to be moving rapidly behind the eyelids. It is associated with increased brain activity and dreaming, but decreased muscle tone.

201 skos:definition Sleep is a state characterized by a reduced responsiveness to sensory stimuli, suppressed locomotor activity and rapid reversibility to wakefulness. It is a process that is evolutionarily conserved in the majority of organisms from worms to humans. In humans it has four stages, each with characteristic and distinctive electroencephalographic (EEG) signatures.

216 skos:definition Sleep deprivation is a state that arises when an organism has less sleep than is optimal, and is followed by a 'rebound' in slow-wave sleep when the opportunity arises. This can be induced experimentally or environmentally (such as shift work), but is also associated with neurological and psychiatric disorders such as dementia, in which normal sleep patterns are disrupted.

225 skos:definition Slow-wave sleep (SWS) refers to phase 3 sleep, which is the deepest phase of non-rapid eye movement (NREM) sleep, and is characterized by delta waves (measured by EEG). Dreaming and sleepwalking can occur during SWS. SWS is thought to be important for memory consolidation.

234 skos:definition Wakefulness is a state of arousal in which there is a conscious monitoring of the environment and there is potential for efficient responsiveness to external stimuli or threats. It is in contrast to the state of sleep in which there is reduced responsiveness to environmental stimuli.
