The neurobiology of circadian rhythms [PDF]
Current Opinion in Pulmonary Medicine, 2009 There is growing awareness of the importance of circadian rhythmicity in various research fields. Exciting developments are ongoing in the field of circadian neurobiology linked to sleep, food intake, and memory. With the current knowledge of critical 'clock genes' (genes found to be involved in the generation of circadian rhythms) and novel techniques

Arrhythmic perch hopping and rhythmic feeding of starlings in constant light: Separate circadian oscillators? [PDF]
, 1984 Perch hopping activity and food intake were recorded in starlings in different intensities of continuous illumination (LL), varying from 0.1 to 1000 lux. Circadian rhythmicity in perch hopping disappeared in 10 lux and all higher intensities. In contrast,

Postnatal constant light compensates Cryptochrome1 and 2 double deficiency for disruption of circadian behavioral rhythms in mice under constant dark. [PDF]
PLoS ONE, 2013 Clock genes Cryptochrome (Cry1) and Cry2 are essential for expression of circadian rhythms in mice under constant darkness (DD). However, circadian rhythms in clock gene Per1 expression or clock protein PER2 are detected in the cultured suprachiasmatic ...

Neurologic Clinics, 2019 In mammals, genetic influences of circadian rhythms occur at many levels. A set of core "clock genes" have been identified that form a feedback loop of gene transcription and translation. The core genetic clockwork generates circadian rhythms in cells throughout the body.

Diurnal rhythms in neurexins transcripts and inhibitory/excitatory synapse scaffold proteins in the biological clock [PDF]
, 2012 The neurexin genes (NRXN1/2/3) encode two families (α and β) of highly polymorphic presynaptic proteins that are involved in excitatory/inhibitory synaptic balance.

Programming effects of maternal stress on the circadian system of adult offspring
Experimental and Molecular Medicine, 2020 Circadian rhythms: Maternal stress can disrupt adult offspring’s biological clock When pregnant mothers are stressed, the fetus’s circadian rhythms are reprogrammed, increasing the risk of health complications later in life.

A cellular model for human daily behaviour [PDF]
, 2010 All the biochemical, physiological or behavioural processes whose period is about 24 hours possess a circadian rhythm. In mammals circadian rhythms control almost all aspects of human daily behaviour and physiology.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
