First-person body view modulates the neural substrates of episodic memory and autonoetic consciousness: A functional connectivity study

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Bruno Herbelin, Thomas William Arthur Bolton, Nathan Quentin Faivre, Baptiste Gauthier, Robin Mange, Florian Lance, Lucie Bréchet

Episodic memory (EM) is classically conceived as a memory for events, localized in space and time, and characterized by autonoetic consciousness (ANC) allowing to mentally travel back in time and subjectively relive an event. Building on recent evidence th ...

Subjective feeling of re‐experiencing past events using immersive virtual reality prevents a loss of episodic memory

Olaf Blanke, Bruno Herbelin, Lucie Bréchet, Andrea Serino, Robin Mange

Introduction: Personally meaningful past episodes, defined as episodic memories (EM), are subjectively re-experienced from the natural perspective and location of one's own body, as described by bodily self-consciousness (BSC). Neurobiological mechanisms o ...

Capturing the spatiotemporal dynamics of self-generated, task-initiated thoughts with EEG and fMRI

Rolf Gruetter, João Pedro Forjaco Jorge, Lucie Bréchet

The temporal structure of self-generated cognition is a key attribute to the formation of a meaningful stream of consciousness. When at rest, our mind wanders from thought to thought in distinct mental states. Despite the marked importance of ongoing menta ...

Investigating the variability of cardiac pulse artifacts across heartbeats in simultaneous EEG-fMRI recordings: A 7T study

Rolf Gruetter, João Pedro Forjaco Jorge, Lucie Bréchet

Electroencephalography (EEG) recordings performed in magnetic resonance imaging (MRI) scanners are affected by complex artifacts caused by heart function, often termed pulse artifacts (PAs). PAs can strongly compromise EEG data quality, and remain an open ...

First-person view of one’s body in immersive virtual reality: Influence on episodic memory

Olaf Blanke, Bruno Herbelin, Andrea Serino, Jane Aspell, Robin Mange, Baptiste Gauthier, Lucie Bréchet, Quentin Antoine Marie Theillaud

Episodic memories (EMs) are recollections of contextually rich and personally relevant past events. EM has been linked to the sense of self, allowing one to mentally travel back in subjective time and re-experience past events. However, the sense of self h ...

Underlying mechanisms of episodic autobiographical memory and self-consciousness

Lucie Bréchet

Cognitive neuroscience has been examining consciousness associated with the subject, that is the self of the conscious experience and its related multisensory processing of bodily signals, the so-called bodily self-consciousness. Different line of research ...

Common Recruitment of Angular Gyrus in Episodic Autobiographical Memory and Bodily Self-Consciousness

Olaf Blanke, Lucie Bréchet, Baptiste Gauthier, Petr Grivaz

Parietal cortex and adjacent parts of the temporal cortex have recently been associated with bodily self-consciousness (BSC). Similarly, growing evidence suggests that the lateral parietal cortex is crucial for the subjective aspects of episodic autobiogra ...
