Neural signatures of complex and real-life memories

Recent advances in cognitive neuroscience increasingly focus on how memory functions in response to rich, temporally extended experiences that approximate the complexity and continuity of everyday life. This symposium brings together recent EEG and fMRI studies investigating the neural correlates of episodic and semantic memory using ecologically grounded paradigms and stimuli, including...
Objects semantically inconsistent with their surrounding scene typically attract attention (i.e., looked at earlier and for longer) and elicit a fronto-central N400 response, reflecting the cognitive effort to resolve contextual mismatches. Yet, it remains unresolved how much semantic information can be extracted before direct fixation, and whether similar extrafoveal processing mechanisms are...
Highly superior autobiographical memory (HSAM) is a rare condition characterized by an extraordinary ability to recall autobiographical information with remarkable accuracy and detail. While previous studies have begun to explore the neural correlates of HSAM, the role of brain oscillations in this phenomenon remains largely unexplored. In this study, we examined an individual with HSAM and...
The ability to organize events in time is a hallmark of episodic memory. While fMRI studies have linked the entorhinal-hippocampal network to temporal judgments and event structure representation, less is known about the broader neural mechanisms supporting these abilities. This EEG study investigated whether temporal memory precision and temporal representation of event structure are related,...
The mnemonic representation of complex events is multidimensional. Although it has been shown that the recollection of complex events jointly recruits the Default Mode Network (DMN) and the FrontoParietal Control Network (FPCN), the extent to which activity within these networks varies according to specific memory dimensions (e.g., what, where, when) remains underexplored. To address this, the...
Traditional accounts describe semantic memory as static and crystallized, often overlooking its episodic origins. Recent theories suggest that conceptual knowledge may emerge from low-dimensional, Cartesian-like representational space (Bellmund, 2018), potentially supported by medial parietal regions (Bottini&Doeller, 2020). However, empirical evidence, especially with high-dimensional,...
