Distinct contributions of Brodmann areas 1 and 2 to body ownership

Roberto Martuzzi, Rolf Gruetter, Olaf Blanke, Sebastian Dieguez Falcon, Wietske Van der Zwaag, Andrea Serino

Although body ownership – i.e. the feeling that our bodies belong to us – modulates activity within the primary somatosensory cortex (S1), it is still unknown whether this modulation occurs within a somatotopically defined portion of S1. We induced an illu ...

Crossed somatoparaphrenia: an unusual new case and a review of the literature

Olaf Blanke, Lukas Heydrich

Somatoparaphrenia is a delusional misidentification and confabulation of body parts, usually arm or hand, opposite to a cerebral lesion, generally of the "minor" right hemisphere. There is some controversy concerning lesion site ( fronto-parietal; parieto- ...

Inferior frontal oscillations reveal visuo-motor matching for actions and speech: evidence from human intracranial recordings

Olaf Blanke, Pär Halje, Silvio Ionta

The neural correspondence between the systems responsible for the execution and recognition of actions has been suggested both in humans and non-human primates. Apart from being a key region of this visuo-motor observation-execution matching (OEM) system, ...

Body part-centered and full body-centered peripersonal space representations

Hervé Lissek, Olaf Blanke, Patrick Marmaroli, Jean-Paul Noel, Andrea Serino, Elisa Canzoneri

Dedicated neural systems represent the space surrounding the body, termed Peripersonal space (PPS), by integrating visual or auditory stimuli occurring near the body with somatosensory information. As a behavioral proxy to PPS, we measured participants' re ...

Numerical Priming Between Touch and Vision Depends on Tactile Discrimination

Olaf Blanke, Laurène Véronique Vuillaume, Roy Salomon, Nathan Quentin Faivre

Although the interaction between vision and touch is of crucial importance for perceptual and bodily self-consciousness, only little is known regarding the link between conscious access and tactile processing. Here, we tested whether the numerical encoding ...

Behavioral, Neural, and Computational Principles of Bodily Self-Consciousness

Mel Slater, Olaf Blanke, Andrea Serino

Recent work in human cognitive neuroscience has linked self-consciousness to the processing of multisensory bodily signals (bodily self-consciousness [BSC]) in fronto-parietal cortex and more posterior temporo-parietal regions. We highlight the behavioral, ...

A novel manipulation method of human body ownership using an fMRI-compatible master-slave system

Olaf Blanke, Wietske Van der Zwaag, Tobias Kober, Masayuki Hara, Giulio Rognini, Roy Salomon

Bodily self-consciousness has become an important topic in cognitive neuroscience aiming to understand how the brain creates a unified sensation of the self in a body. Specifically, full body illusion (FBI) in which changes in bodily self-consciousness are ...

The Cognitive And Neural Time Course Of Empathy And Sympathy: An Electrical Neuroimaging Study On Self-Other Interaction

Olaf Blanke, Manuel Mercier

Although extensively investigated in sociocognitive neuroscience, empathy is difficult to study. The first difficulty originates in its multifaceted nature. According to the multidimensional model, empathy combines emotional, automatic (simulation), cognit ...

Cognitive Loading Affects Motor Awareness and Movement Kinematics but Not Locomotor Trajectories during Goal-Directed Walking in a Virtual Reality Environment

Kamiar Aminian, Olaf Blanke, Oliver Alan Kannape, Arnaud Barré

The primary purpose of this study was to investigate the effects of cognitive loading on movement kinematics and trajectory formation during goal-directed walking in a virtual reality (VR) environment. The secondary objective was to measure how participant ...

Suppression of the auditory N1-component for heartbeat-related sounds reflects interoceptive predictive coding

Olaf Blanke, Bigna Lenggenhager, Lukas Heydrich, Michiel van Elk

Although many studies have elucidated the neurocognitive mechanisms supporting the processing of externally generated sensory signals, less is known about the processing of interoceptive signals related to the viscera. Drawing a parallel with research on a ...

Neurological and Robot-Controlled Induction of an Apparition

Hannes Bleuler, Bruno Herbelin, Olaf Blanke, Lukas Heydrich, Masayuki Hara, Giulio Rognini, Polona Pozeg, Roy Salomon, Andrea Serino

Tales of ghosts, wraiths, and other apparitions have been reported in virtually all cultures. The strange sensation that somebody is nearby when no one is actually present and cannot be seen (feeling of a presence, FOP) is a fascinating feat of the human m ...

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

Olaf Blanke, Valentin Marc Schmutz, Christian Pfeiffer

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 ...

Imagined own-body transformations during passive self-motion

Olaf Blanke, Michiel van Elk

Spatial perspective taking is a crucial social skill that underlies many of our everyday interactions. Previous studies have suggested that spatial perspective taking is an embodied process that involves the integration of both motor and proprioceptive inf ...

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

Olaf Blanke, Christian Pfeiffer, Andrea Serino

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 ...

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

Bruno Herbelin, Olaf Blanke

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 ...

Crossing the hands increases illusory self-touch

Olaf Blanke, Giulio Rognini, Polona Pozeg, Roy Salomon

Manipulation of hand posture, such as crossing the hands, has been frequently used to study how the body and its immediately surrounding space are represented in the brain. Abundant data show that crossed arms posture impairs remapping of tactile stimuli f ...

Nobel Prize centenary: Robert Barany and the vestibular system

Olaf Blanke, Christophe Lopez

The hundredth anniversary of Robert Barany's Nobel Prize in Medicine offers the opportunity to highlight the importance of his discoveries on the physiology and pathophysiology of the vestibular organs. Barany developed the method of caloric vestibular sti ...

Illusory self-identification with an avatar reduces arousal responses to painful stimuli

Olaf Blanke, Christian Pfeiffer

Looking at one's own body has been shown to induce analgesia. In the present work we investigated whether illusory self-identification with an avatar, as induced experimentally through visuo-tactile stimulation, modulates the response to painful stimuli. I ...

Vestibular-Somatosensory Interactions: Effects of Passive Whole-Body Rotation on Somatosensory Detection

Bruno Herbelin, Olaf Blanke, Mariia Kaliuzhna

Vestibular signals are strongly integrated with information from several other sensory modalities. For example, vestibular stimulation was reported to improve tactile detection. However, this improvement could reflect either a multimodal interaction or an ...

The Brain Network reflecting Bodily Self-Consciousness: a functional connectivity study

Roberto Martuzzi, Olaf Blanke, Silvio Ionta, Roy Salomon

Several brain regions are important for processing self-location and first-person perspective, two important aspects of bodily self-consciousness. However, the interplay between these regions has not been clarified. In addition, while self-location and fir ...
