White matter, composed of myelinated axons, results from complex interactions between different cell types, with oligodendrocytes (OLs) and microglia playing integral roles. Microglia, the brain's resident immune cells, regulate oligodendrogenesis through phagocytosis and molecular signaling, for example through cytokines, which promote and inhibit maturation stages of OL lineage cells. Maternal immune activation (MIA) is a recognized risk factor for neurodevelopmental disorders, especially autism spectrum disorder (ASD). The physiological presentation of ASD includes white matter abnormalities and immune dysregulation. Emerging evidence indicates that MIA may reduce microglial reactivity and alter cytokine release in offspring, potentially disrupting the delicate balance required for proper white matter development. Understanding the intricate interplay between oligodendrocytes, microglia, inflammation, and white matter development in the context of MIA provides valuable insights into the etiology of and core symptoms of ASD and possible therapeutic targets.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143976579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social media platforms drive this trend by enabling gameplay sharing and increasing user engagement, potentially reinforcing addictive gaming behaviors. Understanding how gaming content exposure on social media affects brain activity in individuals with internet gaming disorder is crucial. This study aimed to investigate gaming content neural responses on social media in individuals with internet gaming disorder using functional magnetic resonance imaging. We aimed to determine differences in activation patterns that contribute to understanding the neurobiological underpinnings of internet gaming disorder by examining brain activity in these individuals and comparing it to healthy controls. Additionally, we investigated the association of brain activity with clinical characteristics (internet gaming disorder severity and illness duration). The participants with internet gaming disorder demonstrated increased bilateral orbitofrontal cortex, bilateral hippocampus, left precuneus, and right superior temporal gyrus activation in response to gaming-related cues on social media compared to healthy controls. Additionally, internet gaming disorder severity and illness duration correlated with left hippocampus activation levels. These results improve our understanding of how gaming-related content on social media affects individuals with internet gaming disorder. Our findings provide valuable information into the neurobiological features of internet gaming disorder and help develop effective treatment interventions.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a passive oddball paradigm with /u/ as the standard stimulus and /i/ and /y/ as deviants, we recorded and analyzed auditory evoked potentials in fronto-central and centro-parietal regions. Blind participants exhibited significantly faster MMN and N2b latencies than controls and CI users, reflecting enhanced auditory temporal resolution due to cross-modal plasticity. CI users showed reduced P2 and N2b amplitudes, indicating challenges in early sensory processing and conflict monitoring, particularly for the /i/-/u/ contrast. Notably, blind participants had larger P3a amplitudes, emphasizing superior attentional engagement in response to deviant stimuli. Postlingually deafened CI users exhibited greater P3a amplitudes than prelingually deafened users, underscoring the impact of early auditory experiences on cortical responses. These findings demonstrate distinct effects of sensory deprivation on speech processing, with blind individuals showing compensatory neural mechanisms and CI users experiencing sensory and cognitive challenges. The results underscore the need for personalized rehabilitation strategies to enhance outcomes for populations with sensory deprivation and highlight the potential of cross-modal plasticity in auditory rehabilitation.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143983834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, our current understanding of proprioceptive processing at the laminar scale is limited. Empirical findings in primates and rodents suggest a pronounced role of superficial cortical layers, but the involvement of deep layers has yet to be examined in humans. Submillimeter resolution functional magnetic resonance imaging (fMRI) has emerged in recent years, paving the way for studying layer-dependent activity in humans (laminar fMRI). In the present study, laminar fMRI was employed to investigate the influence of proprioceptive somatosensation on M1 deep layer activation using passive finger movements. Significant M1 deep layer activation was observed in response to proprioceptive stimulation across 10 healthy subjects using a vascular space occupancy (VASO)-sequence at 7 T. For further validation, two additional datasets were included which were obtained using a balanced steady-state free precession sequence with ultrahigh (0.3 mm) in-plane resolution, yielding converging results. These results were interpreted in the light of previous laminar fMRI studies and the active inference account of motor control. We propose that a considerable proportion of M1 deep layer activation is due to proprioceptive influence and that deep layers of M1 constitute a key component in proprioceptive circuits.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11998912/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143978173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate which brain regions are involved in the processing of auditory stimuli generated by actions, addressing the question of whether cerebellar forward models, which are supposed to predict the sensory consequences of self-performed actions, similarly underlie predictions for action observation. We measured brain activity with functional magnetic resonance imaging (fMRI) while participants elicited a sound via button press, observed another person performing this action, or listened to external sounds. By applying multivariate pattern analysis (MVPA), we found evidence for altered processing in the right auditory cortex for sounds following both self-performed and observed actions relative to external sounds. Evidence for the prediction of auditory action consequences was found in the bilateral cerebellum and the right supplementary motor area, but only for self-performed actions. Our results suggest that cerebellar forward models contribute to predictions of sensory consequences only for action performance. While predictions are also generated for action observation, the underlying mechanisms remain to be elucidated.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038811/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143981579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An extensive set of studies examined links between GCA and graphical properties of resting state connectomes. However, these studies often involved small samples, applied just a few graph theory measures in each study, and yielded inconsistent results, making it challenging to identify the architectural underpinnings of GCA. Here, we address these limitations by systematically investigating univariate and multivariate relationships between GCA and 17 whole-brain and node-level graph theory measures in individuals from the Adolescent Brain Cognitive Development Study (n = 5937). We demonstrate that whole-brain graph theory measures, including small worldness and global efficiency, fail to exhibit meaningful relationships with GCA. In contrast, multiple node-level graphical measures, especially module degree (within-network connectivity), exhibit strong associations with GCA. We establish the robustness of these results by replicating them in a second large sample, the Human Connectome Project (n = 847), and across a variety of modeling choices. This study provides the most comprehensive and definitive account to date of complex interrelationships between GCA and graphical properties of the brain's intrinsic functional architecture.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143991191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence has been purely correlational-no causal demonstrations show that default mode network-executive control network interaction specifically drives creative performance. We sought causal evidence for default mode network-executive control network coupling in creative thinking using functional near-infrared spectroscopy-brain connectivity neurofeedback, which can endogenously modify functional connectivity through reinforcement learning. Importantly, we employed covert neurofeedback, where participants were unaware of the specific brain activity being trained, allowing for unbiased evaluation of cognitive and neural impacts. In a default-executive neurofeedback condition (n = 15), we entrained coupling between the medial prefrontal cortex and the dorsolateral prefrontal cortex, hubs of the default mode network and executive control network, respectively. We compared this with a default-motor condition (n = 15), entraining coupling between the medial prefrontal cortex and the supplementary motor area. Approximately 24 h later, default-executive neurofeedback led to increased coupling between the default mode network and the executive control network during a creative thinking task (generating creative object uses), extending to broader default mode network regions. Behaviorally, we observed a double dissociation: The default-executive condition increased idea originality, while the default-motor condition improved go/no-go reaction times. We thus provide the first evidence that default mode network-executive control network coupling causally enhances creative performance.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
