These inputs exhibit significant similarity, with 49 nuclei simultaneously innervating both types of neurons. However, GPe<sup>PV</sup> neurons receive a lower proportion of inputs from the cortex and a higher proportion of inputs from the thalamus, compared to GPe<sup>FoxP2</sup> neurons. Clustering analysis indicates that GPe<sup>FoxP2</sup> neurons receive extensive afferent inputs from four nuclear clusters in the brain, whereas GPe<sup>PV</sup> neurons receive afferent inputs from only three clusters, suggesting GPe<sup>FoxP2</sup> neurons may be involved in more diverse functional regulations than GPe<sup>PV</sup>.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Collectively, our results reveal the similarities and differences in the input projections to the two types of neurons in the GPe and lay the neuroanatomic groundwork for further studies to explore the critical physiological functions of GPe.</p>\u0000 </section>\u0000 </div>","PeriodicalId":154,"journal":{"name":"CNS Neuroscience & Therapeutics","volume":"31 6","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cns.70459","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instant optogenetic activation of PVN<sup>OXT</sup> neurons decreased anxiety-like behaviors and promoted fear memory extinction by promoting oxytocin release into the mPFC. Similar to cSD, optogenetic long-term low-frequency (LTF) stimulation of PVN<sup>OXT</sup> neurons promoted a prolonged inhibition of PVN<sup>OXT</sup> neurons and increased anxiety-like behaviors. Interestingly, short-term high-frequency stimulation (HFS) of PVN<sup>OXT</sup> neurons displayed a long-term potentiation of AMPAR-mediated synaptic transmission of PVN<sup>OXT</sup> neurons and could reverse cSD-induced anxiety by promoting the OXT-mediated inhibitory transmission of the mPFC.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Our findings provide key mechanisms and promising deep brain stimulation strategies associated with synaptic plasticity for cSD-induced obsessive anxiety.</p>\u0000 </section>\u0000 </div>","PeriodicalId":154,"journal":{"name":"CNS Neuroscience & Therapeutics","volume":"31 6","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cns.70465","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144214007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
