Circadian desynchronization [PDF]
Interface Focus, 2010 The suprachiasmatic nucleus (SCN) coordinates via multiple outputs physiological and behavioural circadian rhythms. The SCN is composed of a heterogeneous network of coupled oscillators that entrain to the daily light–dark cycles. Outside the physiological entrainment range, rich locomotor patterns of desynchronized rhythms are observed.

Waking experience modulates sleep need in mice
BMC Biology, 2021 Background Homeostatic regulation of sleep is reflected in the maintenance of a daily balance between sleep and wakefulness. Although numerous internal and external factors can influence sleep, it is unclear whether and to what extent the process that ...

Making Memories: Why Time Matters [PDF]
, 2018 In the last decade advances in human neuroscience have identified the critical importance of time in creating long-term memories. Circadian neuroscience has established biological time functions via cellular clocks regulated by photosensitive retinal ...

Chronotype and self-reported sleep, alertness, and mental health in U.S. sailors
Military Medical Research, 2021 Service members are at risk for sleep and psychological conditions affecting their readiness. Chronotype (“morningness” or “eveningness”) is strongly associated with sleep, health and performance.

Circadian rest-activity rhythms predict cognitive function in early Parkinson's disease independently of sleep [PDF]
, 2018 BACKGROUND: Cognitive impairment is a common and debilitating symptom of Parkinson's disease (PD), and its etiology is likely multifactorial. One candidate mechanism is circadian disruption. Although there is evidence of circadian abnormalities in PD, no

Circadian Disruption and Metabolic Disease: Findings from Animal Models [PDF]
, 2010 Social opportunities and work demands have caused humans to become increasingly active during the late evening hours, leading to a shift from the predominantly diurnal lifestyle of our ancestors to a more nocturnal one.

Human circadian variations [PDF]
Journal of Clinical Investigation, 2021 Circadian rhythms, present in most phyla across life, are biological oscillations occurring on a daily cycle. Since the discovery of their molecular foundations in model organisms, many inputs that modify this tightly controlled system in humans have been identified.
