Assessment of Circadian Weighted Radiance Distribution Using a Camera-Like Light Sensor

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Laurent Deschamps, Mirjam Münch, Apiparn Borisuit

Suboptimal light distribution in a room can cause visual discomfort and glare. Next to rods and cones, perception of light is also governed by a third class of photoreceptors, important for circadian rhythm regulation and non-visual functions such as alert ...

Evidence that the Lunar Cycle Influences Human Sleep

Endogenous rhythms of circalunar periodicity (similar to 29.5 days) and their underlying molecular and genetic basis have been demonstrated in a number of marine species [1, 2]. In contrast, there is a great deal of folklore but no consistent association o ...

The Circadian Clock Coordinates Ribosome Biogenesis

Felix Naef, Frédéric Bruno Martin Gachon, Laura Symul, Florian Atger, Celine Jouffe

Biological rhythms play a fundamental role in the physiology and behavior of most living organisms. Rhythmic circadian expression of clock-controlled genes is orchestrated by a molecular clock that relies on interconnected negative feedback loops of transc ...

Healthy lighting: integrating non-visual responses into simulation framework

María Lovísa Ámundadóttir

Lighting is one of the most significant factors in the built environment that affect human health and wellbeing. In addition to stimulating visual responses, light induces a range of non-visual responses in humans including synchronizing circadian rhythms ...

Circadian and Wake-Dependent Effects on the Pupil Light Reflex in Response to Narrow-Bandwidth Light Pulses

Lorette Leon

PURPOSE. Nonvisual light-dependent functions in humans are conveyed mainly by intrinsically photosensitive retinal ganglion cells, which express melanopsin as photopigment. We aimed to identify the effects of circadian phase and sleepiness across 24 hours ...

The Suitability of Radiance for Calculating Circadian Potential

Sharon Jane Gochenour

This research project deals with the suitability of the program Radiance for detailing the spectral qualities of the light received inside a room. More specifically, it asks whether Radiance’s innate RGB algorithm can be used to accurately determine the no ...

Light and chronobiology: Implications for health and disease

Mirjam Münch

Environmental light synchronizes the primary mammalian biological clock in the suprachiasmatic nuclei, as well as many peripheral clocks in tissues and cells, to the solar 24-hour day. Light is the strongest synchronizing agent (zeitgeber) for the circadia ...

The effects of circadian phase, time awake, and imposed sleep restriction on performing complex visual tasks: Evidence from comparative visual search

Mirjam Münch

Cognitive performance not only differs between individuals, but also varies within them, influenced by factors that include sleep-wakefulness and biological time of day (circadian phase). Previous studies have shown that both factors influence accuracy rat ...

Genome-Wide RNA Polymerase II Profiles and RNA Accumulation Reveal Kinetics of Transcription and Associated Epigenetic Changes During Diurnal Cycles

Olivier Martin, Bart Deplancke, Felix Naef, Jacques Rougemont, Nicolas Jean Philippe Guex, Winship Herr, Mauro Delorenzi, Nouria Hernandez, Laura Symul

Interactions of cell-autonomous circadian oscillators with diurnal cycles govern the temporal compartmentalization of cell physiology in mammals. To understand the transcriptional and epigenetic basis of diurnal rhythms in mouse liver genome-wide, we gener ...

Effects of prior light exposure on early evening performance, subjective sleepiness, and hormonal secretion

Jean-Louis Scartezzini, Mirjam Münch, Friedrich Linhart, Apiparn Borisuit

In sighted humans, light intensity, timing, exposure duration, and spectral composition of light are important to entrain the endogenous circadian pacemaker to the 24-h day-night cycle. We tested the impact of two realistic office lighting conditions durin ...
