Mental imagery of self-location during spontaneous and active self-other interactions: an electrical neuroimaging study

Olaf Blanke

Substantial data from the cognitive neurosciences point to the importance of bodily processing for the development of a comprehensive theory of the self. A key aspect of the bodily self is self-location, the experience that the self is localized at a speci ...

Non-invasive brain stimulation of motor cortex induces embodiment when integrated with virtual reality feedback

Olaf Blanke, Andrea Serino, Marco Solcà, Javier Bello Ruiz, Matteo Franza, Thomas Schmidlin

Previous evidence highlighted the multisensory-motor origin of embodiment - that is, the experience of having a body and of being in control of it - and the possibility of experimentally manipulating it. For instance, an illusory feeling of embodiment towa ...

Neural adaptation accounts for the dynamic resizing of peripersonal space: evidence from a psychophysical-computational approach

Olaf Blanke, Andrea Serino

Interactions between the body and the environment occur within the peripersonal space (PPS), the space immediately surrounding the body. The PPS is encoded by multisensory (audio-tactile, visual-tactile) neurons that possess receptive fields (RFs) anchored ...

Fingerprints of brain disease: connectome identifiability in Alzheimer’s disease

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Maria Giulia Preti, Enrico Amico, Sara Stampacchia

Functional connectivity patterns in the human brain, like the friction ridges of a fingerprint, can uniquely identify individuals. Does this “brain fingerprint” remain distinct even during Alzheimer’s disease (AD)? Using fMRI data from healthy and patholog ...

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

Olaf Blanke, Andrea Serino, Bruno Herbelin, 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 ...

The vestibular system: a spatial reference for bodily self-consciousness

Olaf Blanke, Andrea Serino, Christian Pfeiffer

Self-consciousness is the remarkable human experience of being a subject: the “I”. Self- consciousness is typically bound to a body, and particularly to the spatial dimensions of the body, as well as to its location and displacement in the gravitational fi ...

Distinct mechanisms of form-from-motion perception in human extrastriate cortex

Olaf Blanke

The exquisite sensitivity of the human visual system to form-from-motion (FfM) cues is well documented. However, identifying the neural correlates of this sensitivity has proven difficult, particularly determining the respective contributions of different ...

Sense of agency during encoding predicts subjective reliving

Olaf Blanke, Jevita Potheegadoo, Baptiste Gauthier, Nathalie Heidi Meyer, Florian Lance, Juliette Marie Elise Jocelyne Boscheron

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 ...

Increased functional connectivity of the intraparietal sulcus underlies the attenuation of numerosity estimations for self-generated words

Olaf Blanke, Giulio Rognini, Nathan Quentin Faivre, Jevita Potheegadoo, Michael Eric Anthony Pereira, Giedre Stripeikyte

Previous studies have shown that self-generated stimuli in auditory, visual, and somatosensory domains are attenuated, producing decreased behavioral and neural responses compared to the same stimuli that are externally generated. Yet, whether such attenua ...

Body and self in functional neurological disorders*

Olaf Blanke

In this commentary, we comment on the closing remarks from Mark Solms at the 2024 International Neuropsychoanalysis conference in light of recent developments in neurosciences around functional neurological disorders (FND). FND is the new term used to desi ...

Virtual Reality for inward contemplation

Olaf Blanke, Bruno Herbelin, Loup Vuarnesson

When performed at a high level, meditation and contemplative practices can give rise to altered states of consciousness, the study of which is key for cognitive neurosciences. Those effects indeed can help to better understand the underlying mechanisms of ...

Breathing and sense of self: Visuo-respiratory conflicts alter body self-consciousness

Olaf Blanke, Bruno Herbelin

Bodily self-consciousness depends on the processing of interoceptive and exteroceptive signals. It can be disrupted by inducing signal conflicts. Breathing, at the crossroad between interoception and exteroception, should contribute to bodily self-consciou ...

Visuospatial viewpoint manipulation during full-body illusion modulates subjective first-person perspective

Olaf Blanke, Christian Pfeiffer, Valentin Marc Schmutz

Self-consciousness is based on multisensory signals from the body. In full-body illusion (FBI) experiments, multisensory conflict was used to induce changes in three key aspects of bodily self-consciousness (BSC): self-identification (which body 'I' identi ...

Feeling in control of your footsteps: Conscious gait monitoring and the auditory consequences of footsteps

Martin Vetterli, Olaf Blanke, Christof Faller

A fundamental aspect of the “I” of conscious experience is that the self is experienced as a single coherent representation of the entire, spatially situated body. The purpose of the present study was to investigate agency for the entire body. We provided ...

Insula mediates heartbeat related effects on visual consciousness

Olaf Blanke, Bruno Herbelin, Nathan Quentin Faivre, Roy Salomon, Roberta Ronchi, Javier Bello Ruiz, Jonathan Dönz

Interoceptive signals, such as the heartbeat, are processed in a network of brain regions including the insular cortex. Recent studies have shown that such signals modulate perceptual and cognitive processing, and that they impact visual awareness. For exa ...

Agency Deficits in a Human Genetic Model of Schizophrenia: Insights From 22q11DS Patients

Olaf Blanke, Roy Salomon, Maude Schneider, Nathan Quentin Faivre, Oliver Alan Kannape, Mariia Kaliuzhna, Henrique Galvan Debarba

Schizophrenia is a chronic and disabling mental illness characterized by a disordered sense of self. Current theories suggest that deficiencies in the sense of control over one’s actions (Sense of Agency, SoA) may underlie some of the symptoms of schizophr ...

Seeing the phantom: a functional magnetic resonance imaging study of a supernumerary phantom limb

Olaf Blanke, François Lazeyras, Sebastian Dieguez Falcon

OBJECTIVE: Supernumerary phantom limb (SPL) is a rare neurological manifestation where patients with a severe stroke-induced sensorimotor deficit experience the illusory presence of an extra limb that duplicates a real one. The illusion is most often exper ...

Shared electrophysiology mechanisms of body ownership and motor imagery

Olaf Blanke, Nathaniel Evans

Although we feel, see, and experience our hands as our own (body or hand ownership), recent research has shown that illusory hand ownership can be induced for fake or virtual hands and may useful for neuroprosthetics and brain-computer interfaces. Despite ...

The vestibular component in out-of-body experiences: a computational approach

Olaf Blanke

Neurological evidence suggests that disturbed vestibular processing may play a key role in triggering out-of-body experiences (OBEs). Little is known about the brain mechanisms during such pathological conditions, despite recent experimental evidence that ...

Avatar error in your favor: Embodied avatars can fix users’ mistakes without them noticing

Olaf Blanke, Ronan Boulic, Bruno Herbelin, Mathias Guy Delahaye

In immersive Virtual Reality (VR), users can experience the subjective feeling of embodiment for the avatar representing them in a virtual world. This is known to be strongly supported by a high Sense of Agency (SoA) for the movements of the avatar that fo ...
