Brighter Time: A Smartphone App Recording Cognitive Task Performance and Illuminance in Everyday Life

Clocks & Sleep, 2022
Light is an influential regulator of behavioural and physiological state in mammals. Features of cognitive performance such as memory, vigilance and alertness can be altered by bright light exposure under laboratory and field conditions.

Regulatory T cells confer a circadian signature on inflammatory arthritis

Nature Communications, 2020
Circadian rhythms can alter inflammatory state and activity of inflammatory diseases such as rheumatoid arthritis. Here the authors show that extrinsic signals confer a circadian rhythm to regulatory T cell activity, which in turn drives rhythmic ...

Event Timing in Associative Learning [PDF]

, 2012
Associative learning relies on event timing. Fruit flies for example, once trained with an odour that precedes electric shock, subsequently avoid this odour (punishment learning); if, on the other hand the odour follows the shock during training, it is ...

Probabilistic Information Modulates the Timed Response Inhibition Deficit in Aging Mice

Frontiers in Behavioral Neuroscience, 2019
How interval timing is affected by aging constitutes one of the contemporary research questions. There is however a limited number of studies that investigate this research question in animal models of aging.

Distinct circadian mechanisms govern cardiac rhythms and susceptibility to arrhythmia

Nature Communications, 2021
Cardiac function fluctuates greatly across the day and night, but this is not simply a consequence of our changing behaviour. The authors highlight the role of the body’s circadian clock in regulating the heart electrical activity, including a time-of ...

Quantitative characterisation of ipRGCs in retinal degeneration using a computation platform for extracting and reconstructing single neurons in 3D from a multi-colour labeled population

Frontiers in Cellular Neuroscience, 2022
Light has a profound impact on mammalian physiology and behavior. Intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment melanopsin, rendering them sensitive to light, and are involved in both image-forming vision and non ...

Fine-grained timing using genetic programming [PDF]

, 2010
In previous work, we have demonstrated that it is possible to use Genetic Programming to minimise the resource consumption of software, such as its power consumption or execution time. In this paper, we investigate the extent to which Genetic Programming
