Previous studies of natural variants in implicated the Wnt signaling receptor in sleep. Given that the Wnt signaling pathway is highly conserved across species, we hypothesized that (), the murine homolog of , would also have a role in sleep. Using a CRISPR transgenic approach, we removed most of the coding region from C57BL/6N mice. We used a video assay to measure sleep characteristics in -deficient mice. As signaling is known to affect visuospatial memory, we also examined the impact of the deletion on learning and memory using the novel object recognition (NOR) paradigm. -deficient mice had altered sleep compared to littermate controls. The mice did not respond differently to the NOR paradigm compared to controls but did display anxiety-like behavior. Our strategy demonstrates that the study of natural variation in sleep translates into candidate genes for sleep in vertebrate species such as the mouse.

Dopaminergic system gains importance in homeostatic sleep regulation, but the role of different dopamine receptors is not well-defined. 72 h rat electrocorticogram and sleep recordings were made after single application of dopaminergic drugs in clinical use or at least underwent clinical trials. The non-selective agonist apomorphine evoked short pharmacological sleep deprivation with intense wakefulness followed by pronounced sleep rebound.

Human movement behaviour typically unfolds in 24-h cycles, with children being additionally influenced by their parents. Therefore, the aim of this study was to investigate the adherence of 3-10-year-old children to the World Health Organization's (WHO) 24-h movement behaviour guidelines in relation to the behaviours of their mothers/fathers. Data from the Czech cross-sectional FAMIly Physical Activity, Sedentary behaviour and Sleep study included 381 families (with at least one child aged 3-10 years) from urban and rural areas across all three regions of Czechia.

Unlabelled: Klinefelter syndrome (KS) is the most common sex chromosomal aneuploidy in males (47,XXY karyotype in 80-90% of cases), primarily characterized by hypergonadotropic hypogonadism and infertility. It encompasses a broad phenotypic spectrum, leading to variability in neurocognitive and psychosocial outcomes among affected individuals. Despite the recognized correlation between KS and various neuropsychiatric conditions, studies investigating potential sleep disorders, particularly in pediatric subjects, are lacking.
