This review synthesizes current cognitive neuroscience findings and proposes an integrative framework highlighting three key dimensions. First, distinct subregions of the medial temporal lobe (e.g., hippocampus, perirhinal cortex) and large-scale neocortical networks (e.g., ventral and dorsal frontoparietal networks, default mode network) play specialized roles in episodic memory processing. Second, episodic memory representations vary in both content and format, exhibiting stage-specific (e.g., encoding vs. retrieval) and region-specific (e.g., hippocampus vs. neocortex) neural patterns, as well as transformations during memory formation. Third, successful episodic memory relies on dynamic functional connectivity between the hippocampus and neocortex, supported by corresponding structural pathways. Furthermore, age and sex exert significant modulatory effects on hippocampus-neocortex connectivity and associated morphological structure. Future research should further clarify the specific roles of medial temporal and neocortical regions in episodic memory formation and examine developmental changes in inter-regional information flow, with particular attention to how age and sex shape hippocampal connectivity and subregional contributions.</div></div>","PeriodicalId":55331,"journal":{"name":"Brain and Cognition","volume":"191 ","pages":"Article 106374"},"PeriodicalIF":1.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145423532","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}

In this fMRI study, we used multivoxel pattern analysis to investigate how spatial features of tactile stimuli are represented and maintained across a short WM delay period. Our results reveal a dynamic engagement of contralateral primary somatosensory cortex (S1) and anterior superior parietal lobe (SPL) during initial encoding, with a shift toward bilateral posterior SPL involvement during later maintenance. Critically, decoding accuracy in the ipsilateral SPL correlated with individual task performance, suggesting that distinctiveness of WM-related representations in this region supports successful memory retention.

Network analyses revealed increased global efficiency in alpha and gamma bands in older adults, negatively correlating with evasive coping and adaptive cognitive emotional regulation. Hub nodes exhibited over-integration while peripheral connections degraded, suggesting compensatory reorganization that maintains basic function but reduces flexibility in emotional regulation, particularly in theta band and alpha band Default Mode Network and Salience/Ventral Attention networks.

To address this issue, this study systematically investigated the brain-behavior regulatory mechanisms between self-control and cognitive reappraisal by analyzing behavioral-neuroimaging data from 358 participants, combining resting-state functional connectivity (RSFC) and mediation analysis. The behavioral results confirmed a positive correlation between the variables. Moreover, neuroimaging results revealed the functional connectivity between the dorsolateral prefrontal cortex (dlPFC) and superior parietal lobule (SPL) was associated with self-control and played a mediating role in the association with cognitive reappraisal.
