The effects of exercise on brain and behavior in association with SD remain to be further elucidated. This systematic review and meta-analysis appraised behavior and brain tissue alterations in rodents exercised before SD. Sleep deprivation was commonly induced using the flowerpot method. The partial SD protocol (REM sleep deprivation) was frequent (94.73 %), and the multiple platform method (72 h) was the most used for SD (89.47 %).

These changes occurred regardless of SD duration, exercise duration, intensity, time of day, brain region, or animal species. This meta-analysis demonstrates that there is sufficient evidence to state that engaging in exercise prior to sleep deprivation (SD) improves behavioral parameters as well as BDNF and 5-HT levels.

In altricial species like rodents, maternal behavior involves dynamic transitions that provide sensory experiences to developing pups. In this study, we examined how these transitions are influenced by environmental disruptions based on the timing of exposure. Using the limited bedding and nesting (LBN) paradigm, we exposed rat mothers and pups to LBN during three early postpartum windows: postpartum days (PPD) 2-4, 5-6, and 7-9, to assess its effects on infant development. Maternal behavior was analyzed using inferential statistics and network analysis. We assessed offspring outcomes on postnatal days (PND) 13-14, including body weight, eye opening, home-nest odor preference, nipple attachment, and ultrasonic vocalizations (USVs). We included infant outcomes from our prior study in which dams were exposed to LBN from PPD 2-9, with previously reported alterations in maternal behavior. LBN exposure on PPD 2-4 and 5-6 significantly altered maternal behavior, with increased high crouch posture, reduced off-nest behavior, and altered caregiving transitions. Network analysis revealed time window-specific pattern structure alterations, with fewer transitions between active and passive behaviors in LBN dams. No notable changes occurred when LBN was applied during PPD 7-9. Despite alterations in maternal care, pup outcomes remained largely intact. Only the LBN 2-4 group showed reduced body weight, and only LBN 2-9 pups emitted more low-frequency USVs. These findings suggest that while maternal behavior is sensitive to early disruptions, pup outcomes may be differentially affected depending on the timing and duration of exposure. Analyzing caregiving dynamics may contribute to future studies exploring how early caregiving influences long-term neurobehavioral development.</p>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":" ","pages":"115769"},"PeriodicalIF":2.3,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144793376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In HT-22 cells, miR-669g transfection markedly reduced TPH2 expression. To assess its in vivo function, we delivered an AAV-PHP.eB vector encoding miR-669g systemically into mice. Elevated miR-669g expression in the brain suppressed TPH2 expression, reduced cerebral 5-HT levels, and induced behavioral phenotypes, including increased aggression and impaired memory. These findings uncover a previously unrecognized miRNA-enzyme interaction in 5-HT metabolism and suggest that miR-669g may contribute to neuropsychiatric dysfunction through disruption of serotonergic homeostasis.</p>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":" ","pages":"115861"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
