This study aimed to investigate where in the brain cortical thickness (CT) predicts social perception, and which cognitive functions mediate such relationship. To these aims, we used a hierarchical analytical plan: Step 1 identified brain areas' CT that correlate with cognitive measures; Step 2 used stepwise regression to predict social perception outcomes (ToM and AR) from brain areas' CT; Step 3 assessed whether cognitive measures mediate the link between CT and social perception outcomes. The results showed that the CT of the left inferior frontal gyrus (IFG; pars triangularis) predicted both ToM and AR, while the CT of the right superior parietal gyrus (SPL) and of the right anterior occipital sulcus (AOcs) predicted only AR. Mediation models unveiled that visuo-constructive abilities and visual attention mediated the relationship between CT in these areas and social perception outcomes. These findings align with the role of the IFG in mentalizing abilities and underscore the involvement of SPL in visuospatial functions, including mental object rotation and spatial perspective-taking, which are essential for advanced social skills; the role of the AOcs in face processing was also highlighted. Importantly, the findings suggest that fronto-parietal areas are indirectly involved in social perception thorough their involvement in visuo-constructive abilities and visual attention.</p>","PeriodicalId":19299,"journal":{"name":"NeuroImage","volume":" ","pages":"121512"},"PeriodicalIF":4.5,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145258593","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}

The best-known neural organizational principle of information is topographical mapping of specific dimensions. Such maps have been shown for sensorimotor information within sensorimotor cortices (e.g., retinotopy). Here we ask whether there are topographic maps - by analogy, contentopic maps - for mid-level object-related dimensions. We used functional magnetic resonance imaging and population receptive field analysis to measure tuning of neural populations to selected manipulable object-related action-based dimensions. We show maps in dorsal and ventral occipital cortex that code for the score of each object on each target dimension in a linear progression following a particular direction along the cortical surface. Maps for each dimension are distinct, are consistent across individuals, and are not exhausted by participant-specific eccentricity maps, nor by high-definition eccentricity maps derived from available databases. Thus, object information is potentially also coded in multiple topographical maps - i.e., contentopic maps. These contentopic maps refer to intermediate level visual and visuomotor representations, potentially computed from the interaction of lower-level visual features through non-linear transformation following gestalt principles. This suggests that topography is a widespread and non-incidental strategy for the organization of information in the brain that leads to greatly reduced connectivity-related metabolic costs and fast and efficient readouts of information for stimuli discrimination.</p>","PeriodicalId":19299,"journal":{"name":"NeuroImage","volume":" ","pages":"121514"},"PeriodicalIF":4.5,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145258677","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, the specific relationship between these dynamic functional changes and psychological resilience remains unclear. We evaluated neurocomputational changes of the default mode network (DMN) using indices of its functional transitions based on conventional regional mean responses as well as multi-voxel state dynamics, and examined their associations with self-reported resilience in a sample of 336 young adults (171 males, 165 females).

Smaller transitions of DMN regional mean responses were positively associated with more generic resilience measures, though this appeared less robust and potentially susceptible to confounds such as head motion and the size of DMN regions. Associations between resilience and functional state transitions was specific to the DMN, with only limited contributions observed from sensory and salience networks.

Recently, it was also proposed that the brain's network's functional imbalance could primarily drive cognitive decline in neurodegenerative diseases. Here, we investigated whether the anticorrelation between the default mode (DMN) and dorsal attention networks (DAN) reveals different pathology burdens in the AD spectrum. We grouped individuals based on their PET amyloid and cognitive status. Using cross-validated regression models, we investigated whether cognitive impairment can be predicted based on rs-fMRI DMN-DAN anticorrelation. We found that the DMN-DAN anticorrelation differentiates between pathology burdens in AD, as quantified by PET amyloid imaging and cognitive performance. We found that an attenuated DMN-DAN anticorrelation predicted cognitive decline, which was controlled by sex, age, education, and brain tau pathology. Education level, measuring cognitive reserve, did not modulate the association between DMN-DAN anticorrelation and cognitive decline. We demonstrate that the attenuation of the anticorrelation between DMN and DAN is associated with a mechanism of cognitive dysfunction independent of tau pathology and proxies of resilience to cognitive decline or cognitive reserve.
