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

Olaf Blanke, Emanuela De Falco, Baptiste Gauthier, Louis Philippe Albert, Hyeongdong Park, Hyukjun Moon, 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, Friedhelm Christoph Hummel, Pierre Theopistos Vassiliadis, Elena Beanato, Esra Neufeld, Emanuela De Falco, Fabienne Windel, Maximilian Jonas Wessel, Traian Popa, Baptiste Gauthier

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

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

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, Jevita Potheegadoo, Nathalie Heidi Meyer, 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, Baptiste Gauthier, Hyukjun Moon

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

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

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, Constantin Tuleasca, Herberto Dhanis Pedro De Barros Camacho, Elenor Morgenroth, Farnaz Delavari, Eva Blondiaux, Baptiste Gauthier, Gwladys Rey, Lukasz Dawid Smigielski

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

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 ...
