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

open access: yesScientific 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 ...

On the Chronobiology of Cohabitation [PDF]

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2007
Social regulation of animal circadian rhythms may enable individuals in a population to temporally synchronize or segregate their activities within the community. Relatively little is known about the mechanisms for such interindividual temporal adaptations or how the circadian system might be involved.

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.

Short and long sleeping mutants reveal links between sleep and macroautophagy

open access: yeseLife, 2021
Sleep is a conserved and essential behavior, but its mechanistic and functional underpinnings remain poorly defined. Through unbiased genetic screening in Drosophila, we discovered a novel short-sleep mutant we named argus.

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.

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

Chronobiology: Discovery of the molecular mechanisms of circadian rhythm

open access: yesJournal of Mental Health and Human Behaviour, 2018
Advances in the field chronobiology have potential implications for physical as well as mental health and human behavior. Several paradigm-shifting discoveries established key mechanistic principles for the biological clock.

A medullary hub for controlling REM sleep and pontine waves

open access: yesNature Communications, 2023
Rapid-eye-movement (REM) sleep is a distinct behavioral state associated with vivid dreaming and memory processing. Phasic bursts of electrical activity, measurable as spike-like pontine (P)-waves, are a hallmark of REM sleep implicated in memory ...

Methods in field chronobiology [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2017
Chronobiological research has seen a continuous development of novel approaches and techniques to measure rhythmicity at different levels of biological organization from locomotor activity (e.g. migratory restlessness) to physiology (e.g. temperature and hormone rhythms, and relatively recently also in genes, proteins and metabolites).
