The role of orexin and MCH neurons in the hypothalamus in sleep-wake regulation and learning-forgetting balance
Orexin (Orx) and melanin-concentrating hormone (MCH) neurons in the lateral hypothalamic area are central to regulating the sleep-wake cycle and coordinating memory consolidation and forgetting through dynamic homeostatic mechanisms. This review s...

Relationship between sleep duration and hearing loss among adults aged 20–69: exploration of the U–shaped curve pattern
ObjectiveThe National Health and Nutrition Examination Survey (NHANES) data were used to explore the relationship between sleep duration and hearing level among adults aged 20 to 69 years, aiming to verify the association between abnormal sleep du...

The enhancement of nodal properties in the dorsal visual pathway is associated with compensatory mechanisms of visuospatial cognitive abilities following total sleep deprivation
IntroductionVision is the most critical sensory perception in humans, however, total sleep deprivation (TSD) impairs visuospatial cognitive abilities. While evidence suggests that the brain actively counteracts the adverse effects of TSD to preser...

The ubiquitin-proteasome system in circadian regulation
To align sleep–wake behavior and internal physiology with the Earth’s 24-h light–dark cycle, organisms rely on circadian clocks–endogenous timekeeping systems that anticipate and adapt to daily environmental changes. These clocks are governed by t...

Time-dependent cortical responses to siesta disruption in male mice
IntroductionSiestas, or daytime naps, play a critical role in relieving sleep pressure and maintaining physiological balance. However, the effects of siesta disruption remain largely unexplored.MethodsIn this study, we disrupted the natural siesta...

Age-related and sex-specific trends in sleep quality in children and adolescents
IntroductionStrong developmental trends are well described in non-rapid eye movement (NREM) sleep characteristics but also seen in cyclic-alternating-pattern (CAP). The latter shows a bimodal distribution: slow wave dominant (A1) complexes early i...
