Hormone replacement therapy (HRT) is commonly used to mitigate menopausal symptoms, but its use is associated with significant adverse effects. As a result, phytoestrogens, plant-derived estrogens structurally similar to HRTs, are preferred alternatives due to their lack of side effects associated with synthetic HRTs. Among these phytoestrogens, red clover (RC) has emerged as a potent medicinal herb used for the treatment of menopausal symptoms. Thus, the aim of the current study was to evaluate the effects of RC on neurological disorders in estrogen-deficient rats subjected to chronic unpredictable mild stress (CUMS). Ovariectomy (OVX) was performed to induce estrogen deficiency, a condition that closely mimics menopause in females. CUMS, a model of chronic stress, was employed to mimic the stress and anxiety that commonly accompany menopause. Significant changes in physiological, neurobehavioral, biochemical, molecular, and histopathological alterations in the brain hippocampal region were observed in OVX, CUMS, and OVX + CUMS group rats, indicating enhanced neuronal deficits compared with control group rats. Treatment with RC supplementation, 17-β estradiol (E2), and fluoxetine (Flx) significantly restored the pathological alterations caused by both CUMS and estrogen deficiency toward normal. E2 and Flx were included in the study to serve as established treatments for postmenopausal symptoms and stress-related disorders, providing a basis for comparison with RC. In conclusion, our study demonstrated the immense potential of RC in alleviating neurological disorders associated with estrogen deficiency and chronic stress.</p>\u0000 </div>","PeriodicalId":11993,"journal":{"name":"European Journal of Neuroscience","volume":"61 12","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These components can be differentially affected by repetition-induced anterograde interference, where extensive practice on one task impairs performance on subsequent tasks. Repetition leads to rigid movement patterns, making it harder to adapt flexibly to new situations, especially in tasks with sensory uncertainty that require the brain to rely more on past experiences (i.e., sensorimotor memories). To explore this, we tested whether object-use tasks, which depend on the ventral stream, are more affected by this interference than a simpler reach-to-button task with helpful visual cues. Participants completed two tasks: a reach-to-button task involving pressing buttons on either side of a symmetrical object and an object-use task where the same object had a hidden, asymmetric center of mass (CoM). To measure interference, we manipulated how many times participants lifted the object with the weight on one side before switching it to the other side. Our results showed that interference was strongest in the object-use task, where uncertain visual information forced participants to rely on sensorimotor memories. In contrast, the reach-to-button task, supported by helpful visual cues, showed no significant interference. This suggests that tasks relying on the ventral stream are more vulnerable to interference, particularly when sensory feedback is unclear. Our findings highlight how repetition affects different movement types and emphasize the need for a balance between repetition and flexibility in motor learning.</p>","PeriodicalId":11993,"journal":{"name":"European Journal of Neuroscience","volume":"61 12","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejn.70155","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through discussions with major funding agencies, including the Dana Foundation, European Research Council (ERC) and ERA-NET NEURON, we examine how equity, diversity and inclusion (EDI) are integrated into research funding allocation.

While agencies have implemented initiatives such as demographic data transparency, targeted funding mechanisms and bias-awareness training, systemic challenges remain. Variability in data collection practices, barriers in peer review processes and limitations of interventions like double-blind reviews highlight the need for ongoing reform. As EDI policies face growing political scrutiny and active efforts to dismantle existing frameworks, reinforcing and expanding strategies to ensure equitable funding distribution has never been more critical.

Using slice electrophysiology, we find that female, but not male, mice have a reduction in the ex vivo firing rate of VTA dopaminergic neurons following SCVS. Surprisingly, both male and female animals show an increase in inhibitory tone onto VTA dopaminergic neurons and an increase in the firing rate of VTA GABAergic neurons. In males, however, this is accompanied by a robust increase in excitatory synaptic tone onto VTA dopamine neurons. This supports a model by which SCVS recruits VTA GABA neurons to inhibit dopaminergic neurons in both male and female mice, but males are protected from diminished functioning of the dopaminergic system by upregulation of excitatory synapses.

Bloom (1936–2025) passed away. Floyd Bloom was an excellent neuroscientist (Bloom &lt;span&gt;2011&lt;/span&gt;) who added seminal contributions to our understanding of how transmitters, peptides, and alcohol affect brain function. His role in a well-known textbook on neuropharmacology (Cooper et al. &lt;span&gt;2003&lt;/span&gt;) caused my generation to recognize his name immediately. Among the many honorous positions he held, his presidency of the Society for Neuroscience and a position as Editor-in-Chief of the journal &lt;i&gt;Science&lt;/i&gt; stand out. As a former postdoctoral fellow in his research team, I got to know Floyd Bloom as a generous mentor, a highly efficient worker with an almost encyclopedic knowledge, and, most of all, a person with a great sense of humor.&lt;/p&gt;&lt;p&gt;The sad event made me muse about how neuroscience has changed over the past 30 years. Of course, our understanding of the brain has greatly advanced, as has the technology. Whereas life cell imaging was state of the art in 1995, these days, a full chemo- and optogenetic toolbox is at our disposal, and whole-brain single-cell transcriptomics is feasible. Neuroscience is exciting, though it has become complex.&lt;/p&gt;&lt;p&gt;The complexity of today's neuroscience is also apparent from the publication characteristics. Comparing a set of publications in the &lt;i&gt;European Journal of Neuroscience&lt;/i&gt; from 1995 (volume 7, issues 1–6; see Supporting Information for more details) and 2024 (volume 59) shows that the average number of displays per se has not increased. However, a hidden increase is evident from the Supporting Information, which did not yet exist in 1995 (Figure 1A). The number of authors per publication has expanded, as has the number of affiliations and countries per study. All in all, this supports the idea that a bigger team is necessary to come to a single publication.&lt;/p&gt;&lt;p&gt;Interestingly, although the &lt;i&gt;EJN&lt;/i&gt; predominantly published work from European labs in 1995, it has evolved into a more global journal (Figure 1B). For instance, almost 20% of the publications in the 2024 volume had a corresponding author with a Chinese affiliation, as opposed to none in 1995. The percentage of women, either overall, as first author, or as corresponding author, has increased. Based on the increased participation of women in the neuroscience workforce, one can extrapolate the numbers from 1995 and predict those of 2024 (see Supporting Information for details). The predicted values for the overall percentage of female authors (42%) and the percentage of female first authors (54%) are very comparable to the actual percentages in 2024 (42% and 51%, respectively). The actual percentage of female corresponding authors (44%) is somewhat lower than the predicted number (51%), but still substantial. Overall, the contribution of women to &lt;i&gt;EJN&lt;/i&gt; publications nowadays is close to par with that of men.&lt;/p&gt;&lt;p&gt;Job done?
