Structural covariance of cortical morphological measures such as cortical thickness (CT), surface area (SA), and cortical volume (CV) have been applied to identify brain structural differences between patients with neuropsychiatric disorders and healthy controls. However, the precise relationships between structural covariance patterns of different cortical measures remain largely unknown. Here, we optimized the preprocessing and calculation approaches of structural covariances and investigated both global (whole-brain-level) and regional (brain-region-level) structural covariance similarities between CT, SA, and CV in 35,580 individuals. We found that Pearson correlation outperformed partial correlation due to generating fewer negative correlations of uncertain biological significance and principal component regression outperformed the regressions of total intracranial volume and respective global measures in removing global effects and reducing negative correlations. We observed that both global and regional covariance similarities of SA-CV were much higher than those of CT-CV and CT-SA, although they were influenced by the selection of atlases and covariance values. We also found age and sex effects on structural covariances and age effects on covariance similarities. The higher SA-CV covariance similarities than CT-CV indicates that SA contributes more to CV covariance than CT, although CV is derived from both CT and SA. The lack of CT-SA covariance similarities suggests that CT and SA have different covariance patterns and should be used in combination in structural covariance studies.</div></div>","PeriodicalId":19299,"journal":{"name":"NeuroImage","volume":"310 ","pages":"Article 121118"},"PeriodicalIF":4.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143573237","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}

Behavioural evidence suggests that both positive and negative moods can modulate responses to stereotype-laden linguistic content. Early research also highlights the role of colour–gender associations in language processing. However, the neurocognitive mechanisms underlying the interaction between mood, gender stereotype activation, and colour–gender associations remain underexplored. Here, we provide novel neurocognitive evidence that a positive mood actively facilitates access to stereotype knowledge during the stage of semantic integration and re-analysis. Female participants induced into positive or negative moods made stereotype congruency judgments about sentences that were either congruent or incongruent with gender stereotypes, preceded by gendered (pink/blue circles) or gender-neutral (white circles) visual cues. First, the results showed smaller N200 amplitudes in a positive compared to negative mood only for sentences preceded by gender-neutral cues, suggesting that gender-driven expectancies evoked by gendered cues can override mood effects during early lexico-semantic processing. Second, we found smaller N400 amplitudes in a positive compared to negative mood, indicating overall facilitation of lexico-semantic processing in a positive mood, irrespective of stereotype congruency. Finally, we observed larger Late Positive Complex (LPC) amplitudes for stereotypically incongruent than congruent sentences only in a positive mood, pointing to gender stereotype knowledge modulating semantic integration and reanalysis processes in a positive but not negative mood.</div></div>","PeriodicalId":19299,"journal":{"name":"NeuroImage","volume":"310 ","pages":"Article 121116"},"PeriodicalIF":4.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143548091","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}

We sought for cerebral correlates for offset and aftereffects of pain using functional magnetic resonance imaging (fMRI). In 19 patients with chronic pain and 15 pain-free subjects, we gave 10 blocks of pain stimuli by a Peltier-type thermal stimulator on the left volar forearm and recorded pain intensity continuously by a visual analogue scale (VAS), while performing whole-brain fMRI.

Patients showed a longer VAS End Latency, and a larger after-pain activity in the left middle temporal gyrus, the right parietal lobule and, after small-volume correction, the right dorsolateral prefrontal cortex than pain-free subjects. Both VAS End Latency and after-pain activity were positively correlated with the rumination score. Psychophysiological interaction analysis revealed that higher rumination scores were associated with weaker coupling between the middle temporal and prefrontal cortices in patients and pain-free subjects with positive rumination scores.

Although abnormal brain development has been shown to exist in children with ASD, the link between structural brain abnormalities and resting-state functional connectivity (rsFC) disruptions in children with ASD remains understudied. To address this limitation, we utilized the population-based bundle-to-region connectome, providing a detailed understanding of the connectivity between cortical regions and white matter (WM) tracts. By precisely indexing WM-Gray Matter (GM) interactions, we investigated the rsFC of the cortex-associated ROIs to explore the association between structural and rsFC abnormalities and clinical symptoms in young children with ASD. This MRI study identified significant differences in WM structure and rsFC between children with ASD (<em>n</em> = 34) and typically developing children (TD, <em>n</em> = 43). Our results showed that decreased fractional anisotropy (FA) and increased mean diffusivity (MD) and radial diffusivity (RD) in ASD WM tracts compared to TD, particularly in left hemisphere tracts (anterior thalamic radiation [ATR], cingulum, inferior fronto-occipital fasciculus [IFOF], inferior longitudinal fasciculus [ILF], superior longitudinal fasciculus [SLF], and uncinate fasciculus [UF]). Abnormal rsFC was observed in GM areas connected by ATR, cingulum, IFOF, ILF, and SLF. Furthermore, abnormalities in the structural and functional connectivity index (SFCI) within the SLF and cingulum were identified. An association has been observed between these abnormalities and clinical symptoms. Specifically, SLF structural and functional connectivity appear to be associated with repetitive and restrictive behavior (RRB), while cingulum connectivity is associated with communication abilities. In conclusion, young children with ASD exhibit abnormal WM tract structures and associated rsFC abnormalities.
