Circadian Rhythms, Regular Exercise, and Cognitive Performance in Morning-Trained Dancers [PDF]

Clocks & Sleep
Time-of-day and individual circadian variability influence cognitive performance, with later chronotypes being most compromised earlier in the day. On the other hand, moderate-intensity exercise has been shown to enhance cognitive function.

Absence seizures and sleep-wake abnormalities in a rat model of GRIN2B neurodevelopmental disorder. [PDF]

Epilepsia
Abstract Objective Pathogenic mutations in GRIN2B are an important cause of severe neurodevelopmental disorders resulting in epilepsy, autism, and intellectual disability. GRIN2B encodes the GluN2B subunit of N‐methyl‐d‐aspartate receptors (NMDARs), which are ionotropic glutamate receptors critical for normal development of the nervous system and ...

Circadian disruption of feeding-fasting rhythm and its consequences for metabolic, immune, cancer, and cognitive processes [PDF]

Biomedical Journal
The circadian system is composed by a central hypothalamic clock at the suprachiasmatic nuclei (SCN) that communicates with peripheral circadian oscillators for daily coordination of behavior and physiology.

Role of the clock gene homolog aha-1 in the circadian system of Caenorhabditis elegans [PDF]

Frontiers in Neuroscience
BackgroundCircadian rhythms are endogenous and allow organisms to adapt to external daily rhythms of light, temperature and other environmental factors.

Chronic circadian desynchronization of feeding-fasting rhythm generates alterations in daily glycemia, LDL cholesterolemia and microbiota composition in mice [PDF]

Frontiers in Nutrition, 2023
IntroductionThe circadian system synchronizes behavior and physiology to the 24-h light– dark (LD) cycle. Timing of food intake and fasting periods provide strong signals for peripheral circadian clocks regulating nutrient assimilation, glucose, and ...

Sleep and circadian disruption in bipolar disorders: From psychopathology to digital phenotyping in clinical practice. [PDF]

Psychiatry Clin Neurosci
Sleep and biological rhythms are integral to mood regulation across the lifespan, particularly in bipolar disorder (BD), where alterations in sleep phase, structure, and duration occur in all mood states. These disruptions are linked to poorer quality of life, heightened suicide risk, impaired cognitive function, and increased relapse rates.

Environmental, social, and behavioral challenges of the human circadian clock in real-life conditions [PDF]

Frontiers in Physiology
Urban environments, in which ambient light has become a less-reliable entrainer, are challenging for the biological clock to maintain performance. As a consequence, human circadian rhythms are less robust and more variable among individuals.

Epidemiology of sleep patterns and circadian typology in uruguayan children: The contribution of school shifts [PDF]

Sleep Medicine: X
Healthy sleep is defined by the combination of adequate duration, good quality, and regular timing. In children, sleep thus depends on the interplay of individual, parental, organizational, community, and social variables, but only a few studies have ...

The impact of daylight‐saving time (DST) on patients with delayed sleep‐wake phase disorder (DSWPD)

Journal of Pineal Research, Volume 74, Issue 4, May 2023., 2023
Abstract Due to time zones, sun time and local time rarely match. The difference between local and sun time, which we designate by Solar Jet Lag (SoJL), depends on location within a time zone and can range from zero to several hours. Daylight saving time (DST) simply adds 1 h to SoJL, independently of the location.
