Rapid Recalibration of Peri-Personal Space: Psychophysical, Electrophysiological, and Neural Network Modeling Evidence

Bruno Herbelin, Olaf Blanke, Jean-Paul Noel, Andrea Serino, Elisa Pellencin, Tommaso Enrico Bertoni

Interactions between individuals and the environment occur within the peri-personal space (PPS). The encoding of this space plastically adapts to bodily constraints and stimuli features. However, these remapping effects have not been demonstrated on an ada ...

Thought consciousness and source monitoring depend on robotically-controlled sensorimotor conflicts and illusory states

Hannes Bleuler, Olaf Blanke, Pierre Progin, Masayuki Hara, Giulio Rognini, Polona Pozeg, Roy Salomon, Andrea Serino, Marco Solcà, Fosco Bernasconi, Herberto Dhanis Pedro De Barros Camacho, Giedre Stripeikyte

Thought insertion (TI) is characterized by the experience that certain thoughts, occurring in one’s mind, are not one’s own, but the thoughts of somebody else and suggestive of a psychotic disorder. We report a robotics-based method able to investigate the ...

Disownership of body parts as revealed by a visual scale evaluation. An observational study

Dragana Viceic, Olaf Blanke, Roberta Ronchi, Michela Bassolino, Giuseppe Vallar

The disownership of body parts, that most frequently occurs on the left side of the body, contralateral to right-hemispheric lesions, is an infrequent disorder, as usually assessed by interviews asking for dichotomic "yes/no" responses. This observational ...

Method and system for creating an out-of-body experience

Bruno Herbelin, Olaf Blanke, Simon Gallo, Giulio Rognini, Florian Lance

A computer-implemented method for inducing an Out of Body Experience (OBE) in a user through an augmented/virtual reality (AR/VR) system, the OBE including an exit state and a disembodiment state, the method comprising the steps of (a) changing the user vi ...

Somatosensory-visual effects in visual biological motion perception

Olaf Blanke, Manuel Mercier, Pierre Progin, Nathan Quentin Faivre, Wenwen Chang, Kim Do

Social cognition is dependent on the ability to extract information from human stimuli. Of those, patterns of biological motion (BM) and in particular walking patterns of other humans, are prime examples. Although most often tested in isolation, BM outside ...

Imagined paralysis alters somatosensory evoked-potentials

Olaf Blanke, Fred Mast, Christophe Lopez, Estelle Palluel, Silvia Marchesotti

Recent studies employing body illusions have shown that multisensory conflict can alter body representations and modulate low-level sensory processing. One defining feature of these body illusions is that they are sensory driven and thus passive on behalf ...

Hand perceptions induced by single pulse transcranial magnetic stimulation over the primary motor cortex

Olaf Blanke, Andrea Serino, Michela Bassolino, Matteo Franza, Giuliana Sorrentino, Matteo Vissani

Background When single pulse transcranial magnetic stimulation (TMS) is applied over the primary motor cortex (M1) with sufficient intensity, it evokes muscular contractions (motor-evoked potentials, MEPs) and muscle twitches (TMS-evoked movements). Partic ...

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 ...

Coupling Inner and Outer Body for Self-Consciousness

Olaf Blanke, Hyeongdong Park

Although recent studies on self-consciousness emphasized the importance of bodily processing and multisensory integration, such research has focused solely on bodily signals originating from the outside of the body (i.e., exteroceptive bodily signals) or i ...

Reply to: “1.5 Dissociation” of somatoparaphrenia for the upper limb and neglect for the lower limb following a thalamic stroke presenting as flaccid hemiparesis: rehabilitation applications and neuroscience implications

Olaf Blanke

This interesting case study reports on a patient who subsequent to a right thalamic hematoma developed a left hemiparesis, left extrapersonal and personal hemineglect and somatoparaphrenia, but only for the arm not the leg. It is not specifically mentioned ...

Virtual reality add-on device for stereotactic neurosurgery

Philippe Passeraub, Bruno Herbelin, Olaf Blanke

An add-on device for use in combination with a stereotactic apparatus is herein disclosed, the device including a stereotactic adapter, an optical support comprising lenses and a display support adapted to accommodate a virtual reality display. The stereot ...

Depersonalization- and derealization-like phenomena of epileptic origin

Olaf Blanke, Nathaniel Evans, Lukas Heydrich

Objective Depersonalization refers to the sensation of being detached from one's body, often associated with feelings of loss of control over one's own body, actions, or thoughts. Derealization refers to the altered perception of one's surroundings that is ...

Torso-mounted Vibrotactile Interface to Experimentally Induce Illusory Own-body Perceptions

Hannes Bleuler, Olaf Blanke, Masayuki Hara, Giulio Rognini

Recent developments in virtual reality and robotic technologies have allowed investigating the behavioural and brain mechanisms that grounds self-consciousness in the multisensory (e.g. vision and touch) and sensorimotor processing of bodily signals. Yet, ...

Error Augmentation Improves Visuomotor Adaptation during a Full-Body Balance Task

Hannes Bleuler, Mohamed Bouri, Olaf Blanke, Oliver Alan Kannape, Jemina Fasola

Visual amplification of kinematic errors has successfully been applied to improve performance for upper limb movements. In this study, we investigated whether visual error augmentation can promote faster adaptation during a full-body balance task. Healthy ...

Multisensory perceptual awareness: Categorical or graded?

Olaf Blanke, Jean-Paul Noel, Nathan Quentin Faivre

Neural evidence suggests that mechanisms associated with conscious access (i.e., the ability to report on a conscious state) are “all-or-none”. Upon crossing some threshold, neural signals are globally broadcast throughout the brain and allow conscious rep ...
