Recent evidence supports the hypothesis that semantic processing engages both modality-specific and multimodal regions, with the latter serving as integrative \"semantic hubs.\" In this context, our research focuses on the posterior parietal cortices (PPC) and their role in processing space-related semantics. We utilized a low-frequency repetitive Transcranial Magnetic Stimulation (rTMS) protocol targeting the PPC in 11 healthy participants across two tasks. In the first task, in which participants read aloud words from various semantic categories, including space-related terms, no rTMS effects were observed. In the second task, which required participants to respond aloud in a dichotomous manner to questions that either involved or did not involve spatial relations, rTMS over the right PPC impaired response accuracy for both spatial and non-spatial sentences. Additionally, it selectively increased reaction times for spatial sentences, whereas no effect was found for non-spatial sentences. No significant effects emerged following stimulation of the left PPC. The outcomes of the second task, and particularly the increased reaction times when spatial terms were used within sentences to establish spatial relationships, shed light on the multifaceted functions of the right PPC, highlighting its potential role in the semantic processing of space-related words. These findings provide insight into the distributed nature of semantic networks and the specialized contributions of modality-specific areas and multimodal semantic hubs.","PeriodicalId":9145,"journal":{"name":"Brain Structure & Function","volume":"230 6","pages":"106"},"PeriodicalIF":2.7,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144494583","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}

This balance is personal according to individual background, treatment expectations and surgical experience. Nevertheless, preservation of muscle contraction in isolation is no longer an accepted outcome. Motor planning and accurate purposeful execution are essential for useful motor function after surgery. Multiple brain networks work together to achieve this result: local networks focused on motor output, modular networks dedicated to sensorimotor integration and integrative networks responsible for the incorporation of motor function within the overall brain cognition. Intraoperatively, local networks are better probed by asleep techniques whereas integrative networks can only be assessed with awake techniques (modular networks is a crossroad for both techniques). Here, we propose a schematic hierarchical model to address these networks according to an orthogonal plane organization. Local networks are always pivotal given the common final output of motor function. Modular sensorimotor networks achieve their higher specialization within the central lobe given the subcortical connection via specialized U-fiber system underneath central sulcus. Integrative networks are fundamental anterior and posterior to the central lobe within the corona radiata and capsules where the main association fibers that subserve the large brain networks and cognitive hubs are located.","PeriodicalId":9145,"journal":{"name":"Brain Structure & Function","volume":"230 6","pages":"103"},"PeriodicalIF":2.7,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315904","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}

By implementing a multistep approach, it effectively characterizes task/condition-related variations while detecting meaningful covariation patterns between neural and muscular activity. Compared to traditional univariate techniques, this pipeline better addresses the complexity of multimodal datasets, offering a more comprehensive understanding of cognitive-motor dynamics. We demonstrate the utility of this approach using data from a previously conducted experiment on early hominin stone tool use, illustrating how electroencephalography (EEG) and electromyography (EMG) integration can reveal interactions between brain and hand processes across tasks of varying manual complexity. This methodological advancement not only enhances the study of tool-related behaviors but also establishes a standardized framework for future research in neuroarchaeology. Beyond stone tools, this approach could be extended to other forms of material culture, such as ornaments and engravings, contributing to a broader understanding of manual skill development and symbolic behavior.","PeriodicalId":9145,"journal":{"name":"Brain Structure & Function","volume":"230 6","pages":"101"},"PeriodicalIF":2.7,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12170762/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144301145","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}

Structural (SC) and functional (FC) connectivity were examined in this study on 111 (Females = 56) right-handed, healthy, young adults controlled for brain size, using the cluster and region-of-interest (ROI) based algorithms. A nearly moderate correlation between SC and FC was observed for both male and female cohorts, but the degree of correlation was not significantly different between the sexes. Sex differences in SC were found in both intra- and inter-hemispheric clusters and connections, with more differences in the left hemisphere. Compared to males, females were found to have anatomical parcels with higher SC in the left hemisphere involving the language network. Females were also found to have anatomical parcels with higher FC than males in the left hemisphere, including connections to the somatomotor and default mode networks, and lower FC distributed symmetrically between the two hemispheres. These findings highlight the sex differences in the brain structure and function in healthy, young adult populations that may underly behavioral and cognitive differences, including language processing and somatomotor perception.","PeriodicalId":9145,"journal":{"name":"Brain Structure & Function","volume":"230 6","pages":"98"},"PeriodicalIF":2.7,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144301146","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}
