, 2009 Chronobiology is the study of biological processes with respect to time, specifically concerning the four environmental rhythms, namely tide, day, moon and season. It is not concerned with linear time-dependent processes such as aging.

Functional anatomy of non-REM sleep [PDF]
, 2011 The state of non-REM sleep (NREM), or slow wave sleep, is associated with a synchronized EEG pattern in which sleep spindles and/or K complexes and high-voltage slow wave activity (SWA) can be recorded over the entire cortical surface.

Epilepsia, EarlyView.Abstract Recurrent seizures, the hallmark of epilepsy, are influenced by rhythms operating over multiple timescales. Chronobiology is the study of biological timing that aims to explain temporal patterns of events like seizures. Fueled by recent advances in genetics, computational modeling, and device engineering, the chronobiology of epilepsy is now a

Daily Activity Patterns of 2,316 Men and Women from Five Countries Differing in Socioeconomic Development [PDF]
, 2015 Daily rhythmicity in the locomotor activity of laboratory animals has been studied in great detail for many decades, but the daily pattern of locomotor activity has not received as much attention in humans. We collected waist-worn accelerometer data from

Advanced circular statistics in biology: Multiple factors, interactions and repeated measures
Methods in Ecology and Evolution, EarlyView.Abstract Circular data is common across biology and the wider sciences, but presents unique analytical challenges due to their wrapped structure, where endpoints coincide (e.g. 360° = 0°). This requires the use of specific statistical methods. Traditional tests like the Rayleigh and Watson U2 tests remain widely used, but lack flexibility in handling ...

Neuronal Responses to Short Wavelength Light Deficiency in the Rat Subcortical Visual System
Frontiers in Neuroscience, 2021 The amount and spectral composition of light changes considerably during the day, with dawn and dusk being the most crucial moments when light is within the mesopic range and short wavelength enriched.

Chronobiological Aspects of Narcolepsy [PDF]
Sleep, 1994 The circadian, circasemidian and ultradian features of sleep-wake patterns in narcolepsy are reviewed with respect to the hypotheses that chronobiological disturbances might either be specific to the condition or contribute to its symptomatic profile.

Birth, EarlyView.ABSTRACT Background Light changes during the lunar cycle affect rhythms in diverse species. Human studies focusing on whether the moon influences human health have so far neglected the effects of light/dark cycles. The purpose of this study was to investigate whether lunar phases impact perinatal outcomes by considering illumination levels due to day ...
