Females undergo pregnancy, parturition, and lactation, with hormones pivotal to these processes—such as estrogen, prolactin, and oxytocin—also playing essential roles in mediating infant-directed caregiving behaviors. Although the extent of paternal involvement varies widely across species, the same hormones that regulate maternal transitions may be utilized to facilitate paternal behavioral adaptations. Recent advances in single-cell transcriptomics and cell-type-specific genetic manipulations have elucidated the mechanisms through which hormones interact with discrete cell types to drive structural and physiological plasticity within key regions of the brain governing parental behaviors. Furthermore, parental care serves as a valuable model for studying naturally occurring motivated behavioral learning, wherein higher-order cognitive regions and monoaminergic systems play an integrative role. This review highlights recent progress in this field, with a brief discussion on the potential sexually dimorphic engagement of specific hormonal systems.</div></div>","PeriodicalId":10999,"journal":{"name":"Current Opinion in Neurobiology","volume":"95 ","pages":"Article 103113"},"PeriodicalIF":5.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145091271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How do neuronal circuits maintain stable function when their constituent elements are in constant flux? Here, we review recent theoretical and experimental work on interconnected levels, ranging from perpetual changes in synapses driving drifts in tuning of individual neurons to emergent stability at the population level, preserving similarities of activity patterns associated to specific percepts or behaviors. We propose that statistical learning, beyond its well-established roles during development and adaptation to new contexts, is also essential under steady behavioral and environmental conditions to safeguard the stability of representational similarities. We discuss implications for learning, memory, and forgetting. This framework reconciles the apparent paradox between unstable neural activity and stable perception, suggesting that representations are maintained through dynamic processes rather than static neural codes.</div></div>","PeriodicalId":10999,"journal":{"name":"Current Opinion in Neurobiology","volume":"94 ","pages":"Article 103107"},"PeriodicalIF":5.2,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144925248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review highlights recent studies identifying specific cell types and pathways involved in cardiovascular regulation, emphasizing their dynamical role under baseline and threat conditions. Cardiovascular responses are closely tied to behavior through descending brain-to-heart command pathways and ascending interoceptive feedback. Our framework for characterizing cardio-behavioral states under threat identifies rapid-acting “microstates” and slow-changing “macrostates” reflecting context- and time-dependent threat levels. Multidimensional measurements and integrated analytical approaches are required to study neural circuits controlling cardio-behavioral states.
