Neurobiology of sleep (Review) - PMC - PubMed Central (PMC)
Sleep is a physiological global state composed of two different phases: Non-rapid eye movement (NREM) and rapid eye movement (REM) sleep. The control mechanisms of sleep manifest at the level of genetic, biological and cellular organization.
Neuronal Mechanisms for Sleep/Wake Regulation and …
2017年12月5日 · NREM sleep is characterized by high amplitude low-frequency delta oscillations (0.5–4 Hz) and spindles (bursts of 7–15 Hz oscillations) in the EEG, and low postural muscle tone. The EEG during...
The Neurobiological Basis of Sleep and Sleep Disorders - PMC
Neuroanatomy of sleep control. A: two process model for control of the sleep/wake cycle by the circadian clock (process C) and the sleep homeostat (process S). The clock drives a cycling pattern of arousal with a period of ~24 h.
Structure: The anatomy of sleep - Nature
2013年5月22日 · The phases of sleep. In a typical eight-hour sleep, the brain moves through different stages of electrical activity in repeating cycles that last about 90 minutes. Rapid eye movement (REM)...
Functional Neuroanatomy and Mechanism of Sleep
2017年12月5日 · I shall first outline the functional neuroanatomy and mechanism of wakefulness, NREM and REM sleep. The concluding paragraphs will summarize some conceptual mechanism of sleep-wake states as well as cycling of NREM-REM throughout the night.
The interrelation of sleep and mental and physical health is ...
2020年4月9日 · Sleep habits are heritable, associated with brain function and structure, and intrinsically related to well-being, mental, and physical health. However, the biological basis of the interplay of...
Neurobiology of sleep (Review) - PubMed
Among others, serotonin, norepinephrine, histamine, hypocretin (orexin), acetylcholine, dopamine, glutamate, and gamma-aminobutyric acid are known to orchestrate the intrinsic mechanisms of sleep neurobiology. Several models that explain the transition and the continuity between wakefulness, NREM sleep and REM sleep have been proposed.
Neuronal Circuits, Anatomical Substrates, and Mechanism of Sleep ...
2023年11月2日 · This chapter briefly discusses the neuroanatomical substrates and neurotransmitters involved in wakefulness and sleep, including various theories for regulation of rapid eye movement (REM) sleep.
Functional neuroanatomy of sleep and circadian rhythms
The daily sleep-wake cycle is perhaps the most dramatic overt manifestation of the circadian timing system, and this is especially true for the monophasic sleep-wake cycle of humans. Considerable recent progress has been made in elucidating the neurobiological mechanisms underlying sleep and arousal ….
Neuroanatomy and neurochemistry of sleep - PubMed
Sleep is regulated by homeostatic and circadian factors, and the regulation of sleep of mammals shares many molecular properties with the rest state of submammalian species. Several brain structures take part in waking: the basal forebrain, posterior and lateral hypothalamus, and nuclei in the tegmentum and pons.
