Timing is everything: Expert opinion on researching epilepsy rhythms by the ILAE Task Force on Chronobiology. [PDF]

Epilepsia
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

Insomnia subtypes characterised by objective sleep duration and NREM spectral power and the effect of acute sleep restriction: an exploratory analysis

Scientific Reports, 2021
Insomnia disorder (ID) is a heterogeneous disorder with proposed subtypes based on objective sleep duration. We speculated that insomnia subtyping with additional power spectral analysis and measurement of response to acute sleep restriction may be ...

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

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

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

Clocks & 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.

CHRONOBIOLOGY OF DEPRESSION

Psychiatria 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.

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

Frontiers 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.

Chronobiology and nutrition [PDF]

Neuroscience, 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.

Nerve growth factor, brain-derived neurotrophic factor, and the chronobiology of mood: a new insight into the "neurotrophic hypothesis" [PDF]

, 2015
The light information pathways and their relationship with the body rhythms have generated a new insight into the neurobiology and the neurobehavioral sciences, as well as into the clinical approaches to human diseases associated with disruption of ...
