Seasonal Variation in the Responsiveness of the Melanopsin System to Evening Light: Why We Should Report Season When Collecting Data in Human Sleep and Circadian Studies

open access: yesClocks & Sleep, 2023
It is well known that variations in light exposure during the day affect light sensitivity in the evening. More daylight reduces sensitivity, and less daylight increases it.

The influence of timeshift on ciradian rhythm of sensitivity to X-irradiation in mice [PDF]

open access: yes, 1984
For two groups of male C3H mice an eastbound transmeridional flight was simulated by inducing a time shift of the L:D schedule of 8 hr. The assumed flight brought about a maxima) reduction of the daily light and dark span, respectively.

Brain activity during a working memory task after daily caffeine intake and caffeine withdrawal: a randomized double-blind placebo-controlled trial

open access: yesScientific Reports, 2023
Acute caffeine intake has been found to increase working memory (WM)-related brain activity in healthy adults without improving behavioral performances.

Time-on-task decrement in vigilance is modulated by inter-individual vulnerability to homeostatic sleep pressure manipulation

open access: yesFrontiers in Behavioral Neuroscience, 2014
Under sleep loss, vigilance is reduced and attentional failures emerge progressively. It becomes difficult to maintain stable performance over time, leading to growing performance variability (i.e.

An investigation into sleep patterns and the effect of time of day on performance in youth swimmers [PDF]

open access: yes, 2018
The purpose of this study was to investigate sleep patterns in competitive youth swimmers and to establish any time-of-day effect on physiological and psychological variables linked to swimming performance.

CHRONOBIOLOGY OF DEPRESSION

open access: yesPsychiatria Danubina, 2021
Seasonal fluctuations in mood, drive, energy, sleeping- and eating behavior, weight, as well as further important mental and physical functions, and the utilization of light as an effective treatment option were already described by Hippocrates of Kos and Araeteus, the Cappadocian.

Chronobiology and nutrition [PDF]

open access: yesNeuroscience, 2013
Numerous long-term studies have investigated the circadian clock system in mammals, which organizes physiological functions, including metabolism, digestion, and absorption of food, and energy expenditure. Food or nutrition can be a synchronizer for the circadian clock systems, as potent as the external light-dark signal can be.

Application of Bioinformatics in Chronobiology Research

open access: yesThe Scientific World Journal, 2013
Bioinformatics and other well-established sciences, such as molecular biology, genetics, and biochemistry, provide a scientific approach for the analysis of data generated through “omics” projects that may be used in studies of chronobiology. The results
