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

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

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 ...

Fronto-Temporal Disconnection Within the Presence Hallucination Network in Psychotic Patients With Passivity Experiences

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Eva Blondiaux, Roy Salomon, Nathan Quentin Faivre, Jevita Potheegadoo, Giedre Stripeikyte, Kim Do

Psychosis, characterized by hallucinations and delusions, is a common feature of psychiatric disease, especially schizophrenia. One prominent theory posits that psychosis is driven by abnormal sensorimotor predictions leading to the misattribution of self- ...

Modulation of Bodily Self-Consciousness by Self and External Touch

Olaf Blanke, Masayuki Hara, Roy Salomon, Noriaki Kanayama

The full body illusion (FBI) is a bodily illusion based on the application of multisensory conflicts inducing changes in bodily self-consciousness (BSC), which has been used to study cognitive brain mechanisms underlying body ownership and related aspects ...

Sensorimotor conflicts alter metacognitive and action monitoring

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

While sensorimotor signals are known to modulate perception, little is known about their influence on higher-level cognitive processes. Here, we applied sensorimotor conflicts while participants performed a perceptual task followed by confidence judgments. ...

Sensorimotor Induction of Auditory Misattribution in Early Psychosis

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Silvia Marchesotti, Roy Salomon, Andrea Serino, Fosco Bernasconi, Kim Do

Dysfunction of sensorimotor predictive processing is thought to underlie abnormalities in self-monitoring producing passivity symptoms in psychosis. Experimentally induced sensorimotor conflict can produce a failure in bodily self-monitoring (presence hall ...

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 ...

The Bodily Self In Psychosis: Sensorimotor Induction Of Auditory Misattribution In Psychosis Is Linked To Neural Disconnectivity

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Silvia Marchesotti, Roy Salomon, Andrea Serino, Kim Do

OXFORD UNIV PRESS2019

Sensorimotor Induction of Auditory Misattribution in Psychosis is Linked to Neural Disconnectivity

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Silvia Marchesotti, Roy Salomon, Andrea Serino, Kim Do

Background: Schneiderian first rank symptoms (FRS) are characterized by a diminished demarcation of self-other boundaries, causing misattribution of self-generated thoughts and actions to external sources. We have shown that introducing sensorimotor predic ...

Self-attribution of distorted reaching movements in immersive virtual reality

Ronan Boulic, Bruno Herbelin, Olaf Blanke, Roy Salomon, Henrique Galvan Debarba

This study explores the extent to which individuals embodied in Virtual Reality tend to self-attribute the movements of their avatar. More specifically, we tested subjects performing goal-directed movements and distorted the mapping between user and avatar ...

Neural Mechanisms of Presence Hallucination and Passivity Experience Induced by Sensorimotor Conflicts in Healthy Subjects: A Robotics-fMRI Study

Olaf Blanke, Michel Akselrod, Masayuki Hara, Giulio Rognini, Roy Salomon, Nathan Quentin Faivre, Jevita Potheegadoo

Insula mediates heartbeat related effects on visual consciousness

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

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 ...

Rethinking Body Ownership in Schizophrenia: Experimental and Meta-analytical Approaches Show no Evidence for Deficits

Michael Herzog, Olaf Blanke, Maya Roinishvili, Ophélie Gladys Favrod, Mariia Kaliuzhna, Roy Salomon, Albulena Jashari-Shaqiri

Schizophrenia is a severe psychiatric disorder, in which patients experience an abnormal sense of self. While deficits in sensorimotor self-representation (agency) are well docu- mented in schizophrenia, less is known about other aspects of bodily self-rep ...

Neural Sources and Underlying Mechanisms of Neural Responses to Heartbeats, and their Role in Bodily Self-consciousness: An Intracranial EEG Study

Olaf Blanke, Roy Salomon, Fosco Bernasconi, Hyeongdong Park

Bilateral Rolandic operculum processing underlying heartbeat awareness reflects changes in bodily self-consciousness

Bruno Herbelin, Roberto Martuzzi, Olaf Blanke, Javier Bello Ruiz, Roy Salomon, Maria Laura Blefari, Andrea Serino

Exteroceptive bodily signals (including tactile, proprioceptive and visual signals) are important information contributing to self-consciousness. Moreover, prominent theories proposed that visceral signals about internal bodily states are equally or even m ...

Characterizing first and third person viewpoints and their alternation for embodied interaction in virtual reality

Ronan Boulic, Bruno Herbelin, Olaf Blanke, Roy Salomon, Sidney Bovet, Henrique Galvan Debarba

Empirical research on the bodily self has shown that the body representation is malleable, and prone to manipulation when conflicting sensory stimuli are presented. Using Virtual Reality (VR) we assessed the effects of manipulating multisensory feedback (f ...

Unconscious integration of multisensory bodily inputs in the peripersonal space shapes bodily self-consciousness

Olaf Blanke, Roy Salomon, Jean-Paul Noel, Andrea Serino, Marta Lukowska, Nathan Quentin Faivre

Recent studies have highlighted the role of multisensory integration as a key mechanism of self-consciousness. In particular, integration of bodily signals within the peripersonal space (PPS) underlies the experience of the self in a body we own (self-iden ...

Consciousness is more than meets the eye: a call for a multisensory study of subjective experience

Roy Salomon, Nathan Quentin Faivre

Over the last 30 years, our understanding of the neurocognitive bases of consciousness has improved, mostly through studies employing vision. While studying consciousness in the visual modality presents clear advantages, we believe that a comprehensive sci ...

Interplay between Narrative and Bodily Self in Access to Consciousness: No Difference between Self- and Non-self Attributes

Olaf Blanke, Roy Salomon, Jean-Paul Noel, Andrea Serino

The construct of the self is conceived as being fundamental in promoting survival. As such, extensive studies have documented preferential processing of self-relevant stimuli. For example, attributes that relate to the self are better encoded and retrieved ...

Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation

Roberto Martuzzi, Olaf Blanke, Michel Akselrod, Wietske Van der Zwaag, Giulio Rognini, Roy Salomon, Maria Laura Blefari, Andrea Serino, Elisa Canzoneri

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual li ...
