Participants were asked to produce two short sentences describing a man or woman using an object. In the second sentence, they were instructed to use a pronoun to refer to the same person and a noun to refer to a different person. The first ERP experiment revealed that noun conditions elicited more negative ERPs starting at 220 ms, with significant differences in early and later time windows, particularly in the left hemisphere. The second ERP experiment showed divergence at 280 ms, with significant differences between 300 and 400 ms at midline electrodes, again indicating more negative ERPs for nouns. The fMRI experiment identified greater activations for nouns than pronouns in regions like the superior temporal gyrus (STG) and cerebellar vermis, suggesting higher working memory load and lexical retrieval demands for nouns compared to pronouns. Moreover, pronouns elicited an enhanced centro-parietal positivity, indicating increased attentional demands. These findings suggest that while noun processing requires greater working memory and lexical retrieval, pronoun processing engages more attentional resources.

We classified 309 neurons that responded significantly into 8 clusters according to the response dynamics.

Cross-correlation analysis suggested that the complex pattern could be only partly explained by an internal circuit of the deep gray layer. Our results indicate that medial to centrolateral SC neurons simply relay cortical activity, whereas neurons in the deep layers of the anterolateral SC dynamically integrate inputs from the cortex, SNr, CN, and local circuits.

However, the mechanism through which AMPA receptors are removed from the cell surface via neuronal activity is not fully understood. In this study, we showed that small interfering RNA (siRNA)-mediated knockdown of sterile alpha and toll/interleukin receptor motif containing 1 (SARM1) in cultured hippocampal neurons prevented the N-methyl-d-aspartate (NMDA)-induced reduction in cell surface AMPA receptors. However, the control RNA did not affect NMDA-mediated AMPA receptor trafficking. Overexpression of the siRNA-resistant form of SARM1 in SARM1-knocked-down neurons restored AMPA receptor trafficking. However, overexpression of SARM1, which lacks the mitochondrial transport signal, in the SARM1-knocked-down neurons did not restore NMDA-dependent AMPA receptor endocytosis. Moreover, the inhibition of the NADase activity of SARM1 blocked the NMDA-induced reduction of cell surface AMPA receptors. These results suggest that both the mitochondrial localization and NADase activity of SARM1 are essential for NMDA receptor-dependent AMPA receptor internalization in the hippocampal neurons.</div></div>","PeriodicalId":19146,"journal":{"name":"Neuroscience Research","volume":"210 ","pages":"Pages 28-37"},"PeriodicalIF":2.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142350803","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}

AVP, key in regulating water balance, blood pressure, and social behaviors, interplays with these receptors, profoundly impacting empathic responses.

In the hippocampal CA1 and CA3 regions of post-seizure rats, ARC expression significantly exceeded that of control groups.

Given that circadian rhythms are linked to the brain stimulation effects of methamphetamine (METH) and amphetamine, we investigated the effects of METH, 1-(4-methoxyphenyl)-N-methylpropan-2-amine (PMMA), and 1-(benzofuran-5-yl)-N-ethylpropan-2-amine (5-EAPB) on intracranial self-stimulation (ICSS) in wild-type (WT) or Period circadian regulator 2 knockout mice.
