Although its exact purpose remains elusive, sleep has been linked to memory consolidation. In our present study, we investigated the role of sleep quality on sleep-dependent memory consolidation. Previous studies have shown that tequila, a serine protease, affects long-term memory (LTM) consolidation in flies. In the present study, we identified that the hypomorphic mutation in the tequila gene (tequilaf01792 ) leads to increased daytime sleep fragmentation at a very early age in male flies. Intrigued by this observation, we delved into further understanding the role of tequila in sleep-dependent memory consolidation by manipulating sleep duration using pharmacological methods such as GABA-A agonist. Inducing sleep using GABA-A agonist resulted in improved sleep during the day. This further led to a significant improvement in the LTM of these flies when compared with the vehicle-treated flies. In conclusion, daytime-dependent sleep fragmentation is possibly one of the reasons behind the LTM deficit observed in tequilaf01792 flies. Furthermore, we observed that these flies had disturbed sleep only during the daytime, whereas in the night the flies had increased sleep duration. The increased sleep fragmentation during the daytime possibly leads to memory impairment and rescuing sleep fragmentation partially rescues memory consolidation. These outcomes suggest that the tequila gene is involved in sleep-dependent memory consolidation.","PeriodicalId":11617,"journal":{"name":"eNeuro","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12501825/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144859062","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}

It demonstrates good ecological validity, as it allows researchers to study human processing of continuous, naturalistic speech containing dynamic spectrotemporal variations and rich linguistic content. While measures of cortical tracking have strong clinical and research applications, there is a lack of research documenting the reliability of these measures, including how they are affected by the stimulus and how the stimulus is represented, as well as electroencephalography (EEG) acquisition and analysis parameters. In this study, we measured the test-retest reliability of cortical tracking of the speech envelope across different stimuli (an audiobook vs a podcast), stimulus features (broadband envelope and its derivative, multiband envelope and its derivative), reference electrodes (average mastoid vs common average reference), and EEG frequency bands (delta, theta, full) in 26 neurotypical adults (20 female) to assess the potential for cortical tracking to serve as a reliable measure of speech processing. We also examined the amount of data required to achieve stable reliability estimates. We observed moderate to good test-retest reliability for most parameters with as little as 390 s of data, supporting the utility of cortical tracking of the speech envelope as a reliable tool for assessing speech processing. The findings of this study will allow researchers to more effectively design and implement studies on cortical tracking in neurotypical adults and adults with language disorders.","PeriodicalId":11617,"journal":{"name":"eNeuro","volume":"12 8","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12501832/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144946981","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}

Therapeutic approaches to selectively enhance CVN activity have been limited by the lack of defined, translationally relevant targets. Previous studies have identified an important excitatory synaptic pathway from oxytocin (OXT) neurons in the paraventricular nucleus of the hypothalamus to brainstem CVNs, suggesting that OXT could provide a key selective excitation of CVNs. In clinical studies, intranasal OXT has been shown to increase parasympathetic cardiac activity, improve autonomic balance, and reduce obstructive event durations and oxygen desaturations in obstructive sleep apnea patients. However, the mechanisms by which activation of hypothalamic OXT neurons, or intranasal OXT, enhance brainstem parasympathetic cardiac activity remain unclear. CVNs are located in two cholinergic brainstem nuclei: nucleus ambiguus (NA) and dorsal motor nucleus of the vagus (DMNX). In this study, we characterize the colocalization of OXT receptors (OXTRs) in both CVNs and non-CVN cholinergic neurons in the male and female mouse NA and DMNX nuclei. We found that OXT receptors are highly expressed in CVNs in the DMNX, but not in the NA. OXT increases the firing of DMNX CVN, with no effect on NA CVNs. Selective chemogenetic excitation of OXTR+ CVNs in the DMNX-achieved by a combination of Cre- and flp-dependent DREADD expression-evoked a rapid and sustained bradycardia. These findings suggest that activation of DMNX CVNs expressing OXTR with oxytocin may represent a novel translational therapeutic target for restoring autonomic balance in cardiorespiratory disorders.","PeriodicalId":11617,"journal":{"name":"eNeuro","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12376954/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144793795","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}

To address this limitation, we used single-cell RNA sequencing (scRNA-seq) and single-cell spatial transcriptomics together with morphological lineage tracing and immunostaining to describe the cell types forming the interface barrier of the adult murine cortex. We show that the cortical interface is composed of three major cell types, leptomeningeal cells, border astrocytes, and tissue-resident macrophages. On the nonparenchymal side, the interface is composed of transcriptionally distinct PDGFRα-positive leptomeningeal cells that are intermingled with macrophages. This leptomeningeal layer is lined by a population of transcriptionally distinct border astrocytes. The interface neighborhood is rich in growth factor mRNAs, including many leptomeningeal ligands predicted to act on both the border astrocytes and macrophages. On the CNS side of the interface is the relatively cell-sparse cortical layer 1 containing interneurons, microglia, parenchymal astrocytes, oligodendrocyte precursor cells, and oligodendrocytes. Except for the border astrocytes, layer 1 cells are not closely associated with the interface, suggesting that secreted ligands may be the major way the brain interface communicates with the underlying cortical parenchyma. Thus, our data provide a molecular/cellular resource describing the brain interface cell types and their interactions, thereby enabling future studies investigating how this distinct cellular compartment regulates CNS:periphery interactions.","PeriodicalId":11617,"journal":{"name":"eNeuro","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12376965/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144803870","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}

Here, in Drosophila, we developed bichromatic fluorescent reporters to investigate alternative splicing of cacophony (cac)-a gene that codes the pore-forming α1 subunit of the primary neuronal voltage-gated Ca2+ channel (VGCC). These reporters revealed a neuron-specific pattern of exon biases, highly consistent from one animal to the next, suggesting that each neuron splices a unique and consistent portfolio of VGCC isoforms. Stereotypical patterns were observed within motor neurons and multidendritic sensory neurons of female larvae and also within mushroom body Kenyon cells of female adults. In a validation step, we demonstrated that exon splice bias reporting was not dependent on the choice of fluorophores. Additionally, functional properties of the female larval motor neuron terminals could be generally reconciled with the functional properties predicted for the reported exon bias. The application of this technology to a large gene such as cac provides a precedence for effective exon-reporter design for other Drosophila genes.","PeriodicalId":11617,"journal":{"name":"eNeuro","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12370356/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144764781","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}

Nicotine withdrawal significantly elevated anxiety-, depression-, and anhedonia-like behaviors, increased oxidative stress, and upregulated MAO-A activity and GFAP expression, indicating neuroinflammatory effects. Notably, thiamine administration during both nicotine exposure and withdrawal effectively alleviated these behavioral impairments, restored serotonin levels, reduced oxidative stress markers, and mitigated the increase in GFAP expression. Additionally, thiamine alone has been shown to alleviate anxiety- and depressive-like behaviors.

Whether the onset of sensory organ motor control directly influences the development of corresponding sensory cortices remains unknown. Here, we confirm and exploit the late onset of whisking behavior in mice to address this question in the somatosensory system. Using ex vivo electrophysiology, we describe a transient increase in the intrinsic excitability of excitatory neurons in layer IV of the barrel cortex, which processes whisker input, immediately following the onset of active whisking on postnatal days 13 and 14. This increase in neuronal gain is specific to layer IV, independent of changes in synaptic strength, and requires prior sensory experience. Further, these effects are not expressed in inhibitory interneurons in barrel cortex. The transient increase in excitability is not evident in layer II/III of barrel cortex or in the visual cortex upon eye opening, suggesting a unique interaction between the development of active sensing and the thalamocortical input layer in the somatosensory isocortex. Predictive modeling indicates that, immediately following the onset of active whisking, changes in active membrane conductances alone can reliably distinguish neurons in control but not whisker-deprived hemispheres. Our findings demonstrate an experience-dependent, lamina-specific refinement of neuronal excitability tightly linked to the emergence of active whisking. This transient increase in the gain of the thalamic input layer coincides with a critical period for synaptic plasticity in downstream layers, suggesting a role in cortical maturation and sensory processing.","PeriodicalId":11617,"journal":{"name":"eNeuro","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12364433/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144741666","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}
