Changes in spatial self-consciousness elicit grid cell–like representation in the entorhinal cortex

Olaf Blanke, Hyeongdong Park, Hyukjun Moon, Baptiste Gauthier, Emanuela De Falco, Louis Philippe Albert, Corentin Marie Hervé Robert Tasu

Grid cells in the entorhinal cortex (EC) encode an individual’s location in space, integrating both environmental and multisensory bodily cues. Notably, body-derived signals are also primary signals for the sense of self. While studies have demonstrated th ...

Noninvasive modulation of the hippocampal-entorhinal complex during spatial navigation in humans

Olaf Blanke, Elena Beanato, Hyukjun Moon, Esra Neufeld, Friedhelm Christoph Hummel, Maximilian Jonas Wessel, Baptiste Gauthier, Traian Popa, Pierre Theopistos Vassiliadis, Emanuela De Falco, Pauline Menoud, Fabienne Windel

Because of the depth of the hippocampal-entorhinal complex (HC-EC) in the brain, understanding of its role in spatial navigation via neuromodulation was limited in humans. Here, we aimed to better elucidate this relationship in healthy volunteers, using tr ...

Embodiment in episodic memory through premotor-hippocampal coupling

Bruno Herbelin, Olaf Blanke, Nathalie Heidi Meyer, Jevita Potheegadoo, Baptiste Gauthier, Florian Lance, Mariana Babo Rebelo

Episodic memory (EM) allows us to remember and relive past events and experiences and has been linked to cortical-hippocampal reinstatement of encoding activity. While EM is fundamental to establish a sense of self across time, this claim and its link to t ...

Sense of agency during encoding predicts subjective reliving

Olaf Blanke, Nathalie Heidi Meyer, Jevita Potheegadoo, Baptiste Gauthier, Florian Lance

Autonoetic consciousness (ANC), the ability to re-experience personal past events links episodic memory and self-consciousness by bridging awareness of oneself in a past event (i.e., during its encoding) with awareness of oneself in the present (i.e., duri ...

Sense of self impacts spatial navigation and hexadirectional coding in human entorhinal cortex

Olaf Blanke, Nathan Quentin Faivre, Hyeongdong Park, Hyukjun Moon, Baptiste Gauthier

Grid cells in entorhinal cortex (EC) encode an individual’s location in space and rely on environmental cues and self-motion cues derived from the individual’s body. Body-derived signals are also primary signals for the sense of self and based on integrate ...

Virtual Reality platform for functional Magnetic Resonance Imaging in Ecologically valid conditions

Bruno Herbelin, Olaf Blanke, Baptiste Gauthier, Louis Philippe Albert

Functional magnetic resonance Brain Imaging (fMRI) is a key non-invasive imaging technique for the study of human brain activity. Its millimetric spatial resolution is at the cost of several constraints: participants must remain static and experience artif ...

Hippocampal Contribution to Ordinal Psychological Time in the Human Brain

Baptiste Gauthier

The chronology of events in time-space is naturally available to the senses, and the spatial and temporal dimensions of events entangle in episodic memory when navigating the real world. The mapping of time-space during navigation in both animals and human ...

Individual Brain Charting dataset extension, second release of high-resolution fMRI data for cognitive mapping

Baptiste Gauthier

We present an extension of the Individual Brain Charting dataset -a high spatial-resolution, multi-task, functional Magnetic Resonance Imaging dataset, intended to support the investigation on the functional principles governing cognition in the human brai ...

TbCAPs: A toolbox for co-activation pattern analysis

Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Eva Blondiaux, Constantin Tuleasca, Gwladys Rey, Julian Gaviria, Herberto Dhanis Pedro De Barros Camacho, Baptiste Gauthier, Lukasz Dawid Smigielski, Elenor Morgenroth, Farnaz Delavari

Functional magnetic resonance imaging provides rich spatio-temporal data of human brain activity during task and rest. Many recent efforts have focussed on characterising dynamics of brain activity. One notable instance is co-activation pattern (CAP) analy ...

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

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

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 ...

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

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

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 ...

Building the Arrow of Time ... Over Time: A Sequence of Brain Activity Mapping Imagined Events in Time and Space

Baptiste Gauthier

When moving, the spatiotemporal unfolding of events is bound to our physical trajectory, and time and space become entangled in episodic memory. When imagining past or future events, or being in different geographical locations, the temporal and spatial di ...

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

Olaf Blanke, Petr Grivaz, Lucie Bréchet, Baptiste Gauthier

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 ...
