灯光对昼夜节律的影响 Light effects on circadian rhythm 光线对昼夜节律的影响就是光线对昼夜节律的影响。 大多数动物和其他生物的大脑中都有“内置时钟”,用于调节生物过程和日常行为的时间。这些“时钟”被称为昼夜节律。它们允许相对于自然界中的24小时昼/夜周期维护这些过程和行为。尽管这些节奏由各个生物体维持,...
circadian rhythmsleep deprivationaffective disordersBiological rhythm disturbances have been implicated in the development of some mood disorders. Thouh much recent interest has been focusefi on seasonal affective disorder, patients with nonseasonal depression also show evidence in many cases of disturbed ...
— The timing mechanism in plant photoperiodism seems to involve two endogenous circadian rhythms: a light-on (dawn) rhythm and a light-off (dusk) rhythm. Following a period of darkness light may affect flowering without affecting the rhythms, or it may affect flowering by rephasing the rhythms...
Extreme light conditions, as experienced in shift-work schedules, shortened day length during winter months or transmeridian travel, can cause negative health effects, which include cognitive deficits and mood alterations. Aberrant light schedules can cause circadian rhythm alterations and/or sleep disrupt...

Microbial community circadian rhythms have a broad influence on host health and even though light-induced environmental fluctuations could regulate microbial communities, the contribution of light to the circadian rhythms of rhizosphere microbial communities has received little attention. To address this gap...
Melatonin, sleep, and circadian rhythms: Rationale for development of specific melatonin agonists Circadian rhythm sleep disorders (CRSDs), whether chronic or transient, affect a broad range of individuals, including many elderly, those with severe visu... FW Turek,MU Gillette - 《Sleep Medicine》...
Rhythmic genes exhibiting a 24 hr period length are generated through the intersection of two processes: 1) The first is an endogenous circadian clock that persists under constant environmental light and temperature conditions (true “circadian” expression). The persistence of behavioral, physiological,...
Circadian Rhythm: Light-Dark CyclesThe systems biology study of the current epidemic of chronic disease has exposed significant pathophysiology related to disorders of the circadian rhythm. Most commonly recognized are sleep disorders...doi:10.1007/978-3-030-30730-1_34Corey B. Schuler...
core body temperature is highest during theactivity phase and lowest during sleep in both diurnal and nocturnalanimals. The circadian rhythm of melatonin production, however, isnot phased with respect to the activity-rest cycle. It is phased withrespect to the light-dark cycle: melatonin is produc...
