The intricate relationship between metabolism and sleep has been a subject of extensive research, with particular attention given to the role of metabolic signals in sleep regulation. Among these, the brown adipose tissue (BAT) has emerged as a key player, studied from various perspectives including its physiological responses to sleep deprivation, its effects on sleep when activated, the consequences of impaired BAT thermogenesis on sleep patterns, and its metabolic activity across different sleep states. The cumulative evidence from these investigations suggests that BAT plays a crucial role in maintaining an optimal metabolic environment conducive to sleep, a function that becomes particularly significant in contexts of prior sleep loss, inflammatory conditions, and fluctuations in ambient temperature.</div></div>","PeriodicalId":37827,"journal":{"name":"Neurobiology of Sleep and Circadian Rhythms","volume":"18 ","pages":"Article 100122"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Male mice received PLX or control diets (21 days) followed by a midline fluid percussion injury (mFPI) or sham surgery.

Krueger posited that, fundamentally, sleep occurs locally at the level of neuronal/glial assemblies (small networks of neurons and glia) and that the expression of sleep in these assemblies is dependent on their prior use. Neuronal/glial assemblies serve as units of information processing, which consumes energy and increases entropy so that the energy available for further information processing is use-dependently depleted. According to the laws of physics, when energy drops to a lower bound relative to entropy, information processing ceases – which results in local quiescence and locally reduced consciousness and manifests as <em>use-dependent local sleep</em>. The physics-based nature of local sleep implies that it is inevitable, has neither function nor purpose, and is by itself not subject to biology-based evolutionary shaping. But uncontrolled local sleep compromises vigilance and is a threat to safety, which needs to be addressed to ensure survival. This can be accomplished by preemptively regulating sleep at a more global level and in a way that is adapted to the organism's temporal, environmental and ecological niche. Such global sleep allows for energy resupply (through biological processes not unique to sleep) across many neuronal/glial assemblies simultaneously while the organism is relatively safe. Thus, <em>global sleep regulation</em> could be the biology-based adaptation to the physics-based problem of use-dependent local sleep intrusions into wakefulness. Global sleep precludes niche exploitation and thus comes at an opportunity cost – but, unlike local sleep, the regulation of global sleep is subject to evolutionary shaping and amenable to species-specific optimization. Furthermore, a variety of ancillary functions may be served during global sleep to retroactively address biological needs that arose from prior wakefulness. However, serving these functions may be merely opportunistic, as the temporal dynamics of global sleep regulation appear to be proactive rather than retroactive, prioritizing alignment of global sleep and wake timing with the organism's ecological niche. Regardless, the costs of use-dependent local sleep and the management thereof through global sleep regulation are likely to be outweighed by the evolutionary benefit of the presumed source of the local sleep problem – that is, information processing capability, or cognition. In essence, therefore, sleep may just be the unavoidable, but worthwhile, price we pay for cognition.</div></div>","PeriodicalId":37827,"journal":{"name":"Neurobiology of Sleep and Circadian Rhythms","volume":"18 ","pages":"Article 100117"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether CSR promotes changes in structural plasticity that explain ethanol consumption is unknown. Therefore, the present study aimed to determine if CSR induces changes in the dendritic length, branching of the dendritic tree, and spine morphology of the pyramidal neurons from the prelimbic cortex and whether these structural changes are associated with ethanol consumption. For this purpose, adult male Wistar rats were divided into four experimental groups: control, CSR for 7 days/4 h daily, CSR + ethanol exposure, and ethanol exposure. The two-bottle free-choice paradigm was used to measure ethanol intake, and the gentle handling method was used for CSR. At the end of the experiment, the rats were euthanized, and their brains were dissected and processed by Golgi-Cox staining. Sholl analysis was used to characterize structural plasticity. Results show that CSR induced an increase in the ethanol index preference. In addition, ethanol intake and ethanol + CSR increased the total dendritic length, dendritic tree branching, and mushroom spines in prelimbic cortex neurons. In conclusion, changes in structural plasticity associated with CSR and continuous access to ethanol may translate into neuroadaptive changes that favor drug preference and subsequently reinforce addictive behavior.</div></div>","PeriodicalId":37827,"journal":{"name":"Neurobiology of Sleep and Circadian Rhythms","volume":"18 ","pages":"Article 100126"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When nocturnal rodents are subjected to time-restricted feeding during the day, they typically display food anticipatory activity several hours before mealtime. Upon releasing mice to ad libitum feeding, this anticipatory activity is abolished immediately but, following food deprivation, reappears at approximately the same time. However, the mechanism by which rodents retain this time memory of food availability during ad libitum feeding has remained elusive. We utilized the open-source Feeding Experimentation Device 3 (FED3) to measure food-seeking nose-poking behavior. We programmed the FED3 to dispense a pellet by a single left nose-poke, but not by right poke. During daytime restricted feeding, mice exhibited strong anticipatory nose-poking a few hours prior to the daytime meal in both rewarded left and unrewarded right pokes. In addition, mice also exhibited elevation of both rewarded and unrewarded pokes at night, coinciding with mice's previous habitual feeding time. Following ad libitum feeding, rewarded daytime nose-poking gradually moved back to habitual nighttime. However, following food deprivation, anticipatory poking immediately reappeared during the day and night, coinciding with the times of previous daytime restricted feeding and nighttime habitual feeding. Under ad libitum feeding, db/db mice didn't exhibit a clear daily rhythm in food intake. However, these mice exhibited robust food anticipation in both nose-pokes and activity during daytime restricted feeding. Following release back to ad libitum feeding, db/db mice poked sporadically during the day and night, and following food deprivation, anticipation promptly reappeared. These data suggest that there are at least two oscillators underlying food anticipation: one oscillator with a phase that changes according to food availability, and another oscillator with a phase unaffected by feeding conditions.
