3 Απρ 2023 · The mechanism through which sleep is generated and maintained is more of a balance between two systems located within the brain: the homeostatic processes, which are functionally the body’s “need for sleep” center, and the circadian rhythm which is an internal clock for the sleep-wake cycle.
1 Φεβ 2016 · In this article, the authors review the fundamental anatomy and physiology of sleep and its regulation, with an eye toward interactions between sleep and metabolism.
26 Ιαν 2024 · The human body cycles through 2 phases of sleep, (1) rapid eye movement (REM) and (2) nonrapid eye movement (NREM) sleep, which is further divided into 3 stages—N1 to N3. Each phase and stage of sleep includes variations in muscle tone, brain wave patterns, and eye movements.
This chapter provides an overview of basic sleep physiology and describes the characteristics of REM and NREM sleep. Sleep and circadian-generating systems are also reviewed. The chapter ends with a discussion about how sleep patterns change over an individual’s life span.
Physiology provides the tools with which sleep disorders may be phenotyped and genetics advances the clinical domain by identifying risk or vulnerability factors.
1 Απρ 2016 · This review details the physiological processes involved in sleep regulation and the possible functions that sleep may serve.
2 Φεβ 2022 · The REM sleep generation region includes mainly glutamatergic and GABAergic neurons. Sleep timing depends on two factors, sleep debt (process S; homeostasis) and circadian control (process C).
