After ischemic stroke modeling with the middle cerebral artery occlusion (MCAO) method, the changes in infarct volume, neurological deficits, cell apoptosis, microglial polarization, Tim4, mitochondrial fission proteins, mitochondrial membrane potential (MMP), and regulation of reactive oxygen species (ROS) were detected. In oxygen-glucose deprivation (OGD) model, the effects of Tim4 on microglial phenotypes, mitochondrial fission proteins, inflammatory factors, and MMP were evaluated. MCAO increased brain infarct volume, neurological deficits, apoptosis, and the proportion of M1-type microglia. In the OGD model, there was a drop in M2 microglia and a rise in M1 microglia, as well as upregulated tumor necrosis factor-alp (TNF-α) and Interleukin-1 beta (IL-1β). Upregulation of Tim4 was associated with increased levels of ROS in microglia, enhanced expressions of mitochondrial fission factor (MFF) and dynamin-related protein 1 (Drp1), and reduced MMP, which can be reversed by knocking down Tim4 expression. This implied that Tim4 could promote M1 microglial polarization and mitochondrial dynamics. However, Drp1 overexpression offset the effects of Tim4 knockdown on microglial polarization. In conclusion, Tim4 regulates the M1 microglial polarization via mitochondria, serving as a potential therapeutic target for ischemic stroke.</div></div>","PeriodicalId":9083,"journal":{"name":"Brain Research","volume":"1874 ","pages":"Article 150140"},"PeriodicalIF":2.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145896264","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}

Recently, deep learning has been widely used in the study of emotion recognition. However, how to correctly identify emotions still faces a huge challenge. We propose a multi-view deep CNN based on channel attention (MVACNN) for EEG emotion recognition. MVACNN first clustered the channels and divided the channels with high similarity into the same view. Channels within the same view have highly similar patterns of neural activity, which can extract the synergistic features of specific brain regions more intensively and reduce the interference of irrelevant noise. To extract more discriminative features, MVACNN integrates channel attention into each view. Channel attention gives different channel weights to effectively learn the importance of different channels. In addition, MVACNN uses residual blocks to learn the residual variation to better represent the relationship between input and output. The residual structure preserves the original information, improving feature utilization and thus maintaining performance. Experimental results show that MVACNN achieves good results on different datasets.</div></div>","PeriodicalId":9083,"journal":{"name":"Brain Research","volume":"1874 ","pages":"Article 150160"},"PeriodicalIF":2.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145951512","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}
