چکیده
Phillips-Chen-Robinson (PCR) model The PCR model itself combines two earlier models, one describing switching between sleep and wake states as a result of a drive consisting of homeostatic and circadian components3, and one describing the entrainment of the circadian system by light4. Specifically, sleep and wake states occur as a result of mutual inhibition between sleep promoting and wake promoting neurons as described by equations for their mean electric potential, Vv and Vm, respectively,

The effects of self-selected light-dark cycles and social constraints on human sleep and circadian timing: a modeling approach
Why do we go to sleep late and struggle to wake up on time? Historically, light-dark cycles were dictated by the solar day, but now humans can extend light exposure by switching on artificial lights. We use a mathematical model incorporating effects of light, circadian rhythmicity and sleep homeostasis to provide a quantitative theoretical framework to understand effects of modern patterns of l...
متن کاملBlocking Short-Wavelength Component of the Visible Light Emitted by Smartphones’ Screens Improves Human Sleep Quality
Background: It has been shown that short-wavelength blue component of the visible light spectrum can alter the circadian rhythm and suppress the level of melatonin hormone. The short-wavelength light emitted by smartphones’ screens can affect the sleep quality of the people who use these devices at night through suppression of melatonin.Objectives: In this study, we examined the effects of co...
متن کاملEffect of Eight Weeks of Endurance Training in Light and Dark Phases of Circadian Rhythm on the Oxidative Stress Index in Pancreas of Diabetic Mice
Introduction: Chronic hyperglycemia is associated with an increase in cellular damage due to oxidative stress in pancreatic tissue. The effect of exercise in different phases of the circadian cycle on protecting pancreatic tissue from oxidative stress in diabetic patients is unknown. The aim of this study was to investigate the effect of eight weeks of endurance training in light and dark phase...
متن کاملCIRCADIAN VARIATION OF THE ACUTE TOXICITY AND NOCICEPTIVE ACTIVITY OF AMINOPHYLLINE IN MICE
The circadian variation of the toxicity and nociceptive actIvity of aminophylline as an important methylxanthine was studied in mice. The animals were housed under controlled light-dark cycles for at least 2 weeks. Acute toxicity was determined by LD50. Hot-plate test was used for determination of thermal pain threshold. Doses of 200, 250, 280 and 340 mg/kg of aminophylline were injected i...
متن کاملPlasticity of the Intrinsic Period of the Human Circadian Timing System
Human expeditions to Mars will require adaptation to the 24.65-h Martian solar day-night cycle (sol), which is outside the range of entrainment of the human circadian pacemaker under lighting intensities to which astronauts are typically exposed. Failure to entrain the circadian time-keeping system to the desired rest-activity cycle disturbs sleep and impairs cognitive function. Furthermore, di...
