Throughout that time, however, research on the neural and behavioral consequences of HCs was minimal and plagued by poor methodology. HC effects – and users – were assumed to be homogenous. Fortunately, there has been a recent upswell in the number and quality of investigations, affording tentative conclusions about the roles of HCs in spatial cognition and mental health, particularly depression. Thus, this paper leverages findings from the past few years to highlight the heterogeneous aspects of use that seem to matter for behavior – ranging from variation in hormonal contraceptive formulations and routes of administration to individual differences among users linked to age and reproductive health history. This paper closes with five tips for future research that will help capture and clarify heterogeneity in potential relations between HCs and behavior, namely data collection, regional access, lifespan factors, gender, and collaboration. HCs are sociopolitically provocative and research on their potential behavioral neuroendocrine impacts is becoming increasingly popular. It is, therefore, imperative for scientists to conduct replicable and robust empirical investigations, and to communicate findings with the nuance that the heterogeneity among users and effects requires.</p></div>","PeriodicalId":13001,"journal":{"name":"Hormones and Behavior","volume":"164 ","pages":"Article 105574"},"PeriodicalIF":2.5,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141554641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Linear mixed effects analyses demonstrated that infants with more pronounced baby schema features were rated as cuter and participants indicated greater motivation to take care of them. Furthermore, infants with more pronounced baby schema features elicited stronger smiling responses and enhanced P2 and LPP amplitudes compared to infants with less pronounced baby schema features. Importantly, individual differences significantly predicted baby schema effects. Specifically, women with low <em>OXTR</em> methylation and high nurturance motivation showed enhanced differentiation in automatic neurophysiological responses to infants with high and low levels of baby schema features.

The literature was screened and studies meeting strict inclusion criteria were included in the analysis. Eligible studies included female ovariectomized rodents with an adequate vehicle for the estrogen treatment, with an outcome of spatial learning and memory in the Morris water maze.

Subgroup analyses were developed a priori to assess important factors. The overall analysis favoured treatment for the later stages of training and for the probe trial. Factors including the type of estrogen, route, schedule of administration, age of animals, timing relative to ovariectomy, and duration of treatment were all found to be important. The subgroup analyses showed that chronic treatment with 17β-estradiol, either cyclically or continuously, to young animals improved spatial recall.

Activation of nuclear ERα results in classical genomic signaling leading to transcriptional changes that occur over hours to days. In contrast, activation of ERα localized to the membrane results in rapid signaling with effects occurring in seconds to minutes. The goal of the current study was to determine the role of membrane ERα in spatial memory. Female wildtype (WT) and transgenic mice that lack membrane ERα and express nuclear only ERα (NOER) were trained on an eight-arm radial-maze task. Following training, mice were tested on delay trials, in which delays ranging from 30 min to 5 h were inserted between the 4th and 5th arm choices. Performance was measured by number of proactive and retroactive errors. Proactive errors are short-term working memory errors defined by reentries into arms previously visited during the post-delay period or errors made during the pre-delay period. Retroactive errors are delay-dependent memory errors, defined as reentries into arms during the post-delay that were previously visited during the pre-delay. Consistent with a role for membrane ERα in rapid signaling, NOER mice made more proactive errors than WTs across all delays. NOER mice made more retroactive errors than WTs only after the 5-h delay. WT and NOER mice performed similarly on elevated plus maze and open field tests indicating no effects of membrane ERα on anxiety-related behavior or locomotor activity. Results reveal that membrane ERα plays important roles in both short-term and longer-term delay-dependent memory either directly or potentially indirectly through a role in the regulation of estradiol levels via the hypothalamic-pituitary-gonadal axis.</p></div>","PeriodicalId":13001,"journal":{"name":"Hormones and Behavior","volume":"164 ","pages":"Article 105597"},"PeriodicalIF":2.5,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0018506X24001223/pdfft?md5=c1dd3945cbc1dac8b9ad75dcc1d0640c&pid=1-s2.0-S0018506X24001223-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141467611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
