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. In db/db mice, the first oscillator is likely impaired, and the second oscillator is unaffected.</div></div>","PeriodicalId":37827,"journal":{"name":"Neurobiology of Sleep and Circadian Rhythms","volume":"18 ","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143550080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In mammals and cockroaches, each of the two master clocks consists of a core region that receives information from the eyes and a shell region from which most of the output projections originate, whereas in flies and several other insects, the master clocks are distributed in lateral and dorsal brain regions. In all cases, morning and evening clock neurons seem to exist, and the communication between them and other populations of clock neurons, as well as the connection across the two brain hemispheres, is a prerequisite for normal rhythmic function. Phenomena such as rhythm splitting, and internal desynchronization are caused by the \"decoupling\" of the master clocks in the two brain hemispheres or by the decoupling of certain clock neurons within the master clock of one brain hemisphere. Since the master clocks in flies contain relatively few neurons that are well characterized at the individual level, the fly is particularly well suited to study the communication between individual clock neurons.

A total of 40 male Wistar rats were divided into five groups: a control group, a group with circadian rhythm disruption (CIR), a group with sleep deprivation during the light phase (SD-AM), a group with sleep deprivation during the dark phase (SD-PM), and a group with combined sleep deprivation and circadian rhythm disruption (SD-CIR). Sleep deprivation was induced using a specialized machine, depriving rats of sleep for 4 h daily, while circadian rhythm disruption was achieved through a 3.5-h light/dark cycle. After four weeks, kidney tissues and blood samples were collected for histological and biochemical analyses. The results showed that all experimental groups exhibited reduced water intake, with the CIR and SD-CIR groups also showing significantly lower food intake and reduced weight gain compared to controls. Oxidative stress markers revealed increased serum malondialdehyde (MDA) levels in the SD-PM and SD-CIR groups. Despite these metabolic and oxidative changes, histological examination of the kidneys revealed no significant alterations in renal structure or function across the groups. This study highlights the negative effects of chronic partial sleep deprivation and circadian rhythm disruption on feeding behavior, weight gain, and oxidative stress in rats.

Here, we modeled the incorrect timing of physical activity in nightshift workers in male Wistar rats, by restricting running wheel access to the innate inactive (light) phase (LR). Controls included no wheel access (NR); access only during the innate active (dark) period (DR); or unrestricted (<em>ad libitum</em>) access (ALR). LR did not shift the phase of the muscle or liver clock, but dampened the muscle clock amplitude. As our previous study demonstrated that light-phase restricted feeding did shift the liver clock, but made the muscle clock arrhythmic, we next combined the time restriction of wheel and food access to either the light phase (LRLF) or dark phase (DRDF). LRLF produced a ∼12 h shift in the majority of clock gene rhythms in both skeletal muscle and liver. On the other hand, DRDF was most effective in reducing body weight and the accumulation of fat mass. Therefore, in order to shift the muscle clock in male Wistar rats, synergy between the timing of feeding and physical activity is necessary.
