The correlation between the functional magnetic resonance imaging results and the acquired clinical indicators was determined using Pearson's correlation analysis. In the face-name association memory task, activation of the hippocampus and parahippocampal gyrus was found to be negatively correlated with the Short Form of the Geriatric Depression Scale score. Precentral gyrus and precuneus activation positively correlated with the percentage of correct answers in the one-back task. In the working memory N-back task, activation of the superior parietal lobule was positively correlated with the percentage of correct answers in the zero-back task. Age and activation in the hippocampus and parahippocampal gyrus are positively correlated. Depression, age, and sex significantly affected brain activity. Activation of the precentral gyrus, superior parietal lobule, and precuneus influences N-back task competency. Overall, this study is the first to analyze the correlation between brain function and clinical indicators of amnestic mild cognitive impairment.","PeriodicalId":9192,"journal":{"name":"Brain Imaging and Behavior","volume":" ","pages":"732-745"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12198334/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143964889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In MDD, high polygenic risk independently influenced changes in left dorsolateral superior frontal gyrus CBF, while EN plays a role in individuals with a higher genetic risk for MDD.

This loss of automaticity is demonstrated by worsening gait performance while dual tasking. Functional connectivity between the cerebellar vermis and cortex have previously been associated with spatiotemporal measures of gait in PD. The objective of this study was to determine whether this corticocerebellar connectivity is associated with gait automaticity as measured by dual task interference in PD FOG. 55 participants with PD were recruited (38 FOG, 17 non-FOG controls) to undergo a resting-state functional magnetic resonance imaging scan. Gait automaticity was quantified using spatiotemporal metrics from single and dual task time up and go trials. FOG participants demonstrated shorter step length and gait velocity compared to non-FOG PD controls. A trend toward greater dual task interference of step length in the FOG group was found. Using a seed-based connectivity approach we observed that FOG participants have greater vermis connectivity than non-FOG PD participants to several cortical regions including the superior parietal lobe, supplemental motor area, precentral gyrus and posterior cingulate (voxel threshold p < 0.01, cluster FWE corrected p < 0.05). Meanwhile, vermis connectivity to the occipital cortex was reduced in FOG participants relative to non-FOG controls. Dual task interference of step length among the FOG group correlated with the degree of vermis connectivity to the sensorimotor cortex and superior parietal cortex (voxel threshold p < 0.01, cluster FWE corrected p < 0.05). We conclude that increased corticocerebellar connectivity may be associated with loss of gait automaticity in individuals with PD FOG.","PeriodicalId":9192,"journal":{"name":"Brain Imaging and Behavior","volume":" ","pages":"637-646"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12198313/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether such individual patterns are present in perinatal brains, and which morphological attributes or cortical regions better characterize the individual differences of neonates remain unclear. In this study, we proposed a deep learning framework that projected three-dimensional spherical meshes of three morphological features (i.e., cortical thickness, mean curvature, and sulcal depth) onto two-dimensional planes through quasi-conformal mapping, and employed the ResNet18 and contrastive learning for individual identification. We used the cross-sectional structural MRI data of 461 infants, incorporating with data augmentation, to train the model and fine-tuned the parameters based on 41 infants who had longitudinal scans. The model was validated on a fold of 20 longitudinal scanned infant data, and remarkable Top1 and Top5 accuracies of 85.90% and 92.20% were achieved, respectively. The sensorimotor and visual cortices were recognized as the most contributive regions in individual identification. Moreover, morphological fingerprints successfully predicted the long-term development of cognition and behavior. Furthermore, the folding morphology demonstrated greater discriminative capability than the cortical thickness. These findings provided evidence for the emergence of morphological fingerprints in the brain at the beginning of the third trimester, which may hold promising implications for understanding the formation of individual uniqueness, and predicting long-term neurodevelopmental risks in the brain during early development.","PeriodicalId":9192,"journal":{"name":"Brain Imaging and Behavior","volume":" ","pages":"666-677"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diffusion tensor imaging studies employing tract-based spatial statistics have shown microstructural abnormalities in white matter among individuals exposed to early life adversity; however, robust conclusions are yet to be drawn. This systematic review synthesizes findings of previous tract-based spatial statistics studies to identify the white matter alterations in adult brains exposed to early life adversity, in papers with methodological consistency. The literature search (April 2024) was conducted to identify tract-based spatial statistics studies that compared diffusion metrics between adults exposed to early life adversity and adults not. Embase, Pubmed, and PsycInfo were searched, retrieving 2458 articles. Following deduplication, 1739 titles and/or abstracts were screened. 1699 articles were excluded, and 40 full texts were reviewed. Seven articles, reporting on 764 subjects, met the inclusion criteria and were included in the narrative synthesis. Compared to controls, adults exposed to early life adversity showed lower fractional anisotropy values in white matter tracts of the limbic and visual processing systems, specifically the anterior thalamic radiation, inferior longitudinal fasciculus, corona radiata, uncinate fasciculus, inferior fronto-occipital fasciculus, and cingulum bundle. This systematic review highlights that early life adversity may underlie emotional dysregulation and contribute to an increased risk of psychopathology in later life and explores the potential neurobiological mechanisms that underpin these structural changes. Understanding these associations is crucial for developing targeted interventions aimed at mitigating the long-term impact of early life adversity.","PeriodicalId":9192,"journal":{"name":"Brain Imaging and Behavior","volume":" ","pages":"785-799"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12198288/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143974880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical assessments primarily utilized the Beck Scale for Suicide Ideation (BSSI) and the Trail Making Test (TMT). Differences in fractional anisotropy (FA) values among the groups were compared using Tract-Based Spatial Statistics (TBSS). The identified differential brain regions were designated as regions of interest (ROIs), and covariance analysis was employed to compare the FA values among the three groups. Partial correlation analyses were conducted between the FA values in the ROIs and clinical symptoms. Differences in brain regions identified through TBSS were observed in the genu of the corpus callosum and the left anterior corona radiata (p < 0.05). Covariance analysis revealed that the BDSI + group exhibited significantly lower FA values in these regions compared to the HCs (p < 0.05). Partial correlation analyses showed that the FA values in the genu of corpus callosum were negatively correlated with BSSI scores (r = -0.592, p = 0.026) and TMT-A scores (r = -0.642, p = 0.013).
