ZH performed a perception and an improvisation task inside an fMRI scanner. Because no adequate control group exists for a tabla master of ZH’s caliber, we employed internal controls where each paradigm featured an experimental task compared to a matched control. In our first paradigm, ZH listened to English speech or tabla bols; listening to bols activated ZH’s language and proprioceptive areas more than listening to speech. In our second paradigm, ZH performed an unconstrained improvisation on a single tabla drum, resulting in the deactivation of the dorsolateral prefrontal cortex (DLPFC), a region known to be involved in conscious self-monitoring. DLPFC deactivation has been observed in jazz experts when improvising, suggesting a common neural mechanism of musical improvisation across musical traditions and genres.

The present study investigated the efficacy of combining transcranial direct current stimulation (tDCS) with a behavioral intervention – Rhythmic Reading Training (RRT) – to improve reading skills in university students with dyslexia. Twenty participants (aged 19–26) diagnosed with dyslexia completed a 10-day intervention comprising daily 30-minute sessions of RRT and 15 min of concurrent online tDCS. A constant current of 1.5 mA was applied for 20 min in a bipolar montage with the anode over the left temporoparietal junction (TPJ) and the cathode over the right TPJ. Participants were randomly assigned to either an active or sham tDCS condition, matched for sociodemographic characteristics, intellectual functioning, and severity of reading difficulties. Reading performance, verbal working memory, rapid automatized naming (RAN), and rhythm perception were assessed at baseline (pre-training), immediately after the intervention (post-training), and at a 4-week follow-up. Results showed that the behavioral intervention alone was sufficient to engage phonological processing, as evidenced by significant improvements in nonword reading speed in both the active and sham groups. Additionally, tDCS produced sustained gains in the most ecologically valid measure of reading, namely, text reading speed. These findings indicate that a short, intensive RRT program effectively improves reading speed in university students with dyslexia and that combining RRT with active tDCS over the left temporoparietal cortex may enhance the durability of text reading speed gains through brain plasticity mechanisms.</div></div>","PeriodicalId":55331,"journal":{"name":"Brain and Cognition","volume":"194 ","pages":"Article 106408"},"PeriodicalIF":1.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146183494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental results showed that (1) behaviorally, the inter-individual coordination index revealed that individuals showed higher coherence when coordinating in the mirror-symmetric direction as compared to non-mirror symmetric mode, (2) cerebral activity was lower in the frontal-parietal region during coordination of pairs executing movements face-to-face as compared to stepping alone, and (3) inter-brain synchronization was significantly enhanced during both interpersonal coordination modes compared to solo stepping, indicating strengthened neural coupling between partners during coordinated action.

Previous research using functional transcranial Doppler Sonography (fTCD) suggested a left-lateralized pattern for multiplication and bilateral activation for subtraction, but these findings were limited by small samples and uncontrolled task difficulty. The present study aimed to replicate and extend these results using a substantially larger sample. Participants completed multiplication and subtraction tasks of varying difficulty while cerebral blood flow velocity (CBFV) in the middle cerebral arteries was recorded with fTCD. Results confirmed significant left-hemispheric activation for multiplication but not subtraction. Increased task difficulty also enhanced left-lateralization across both operations. These findings align with the Triple Code Model, which links multiplication to left-lateralized verbal memory retrieval and subtraction to bilateral magnitude processing. The increase in left-lateralization for complex tasks may reflect additional engagement of verbal working memory, such as subvocal rehearsal. Hemispheric asymmetries for both operations were positively correlated, suggesting shared neural resources. Overall, our study validates fTCD as a reliable method for assessing arithmetic lateralization and highlights the importance of task difficulty and individual variability. These findings advance understanding of arithmetic processing by demonstrating operation- and difficulty-dependent specialization and the role of domain-general resources.</div></div>","PeriodicalId":55331,"journal":{"name":"Brain and Cognition","volume":"193 ","pages":"Article 106391"},"PeriodicalIF":1.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145806475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
