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

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon, Maude Schneider, 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 ...

Differential effects of vestibular processing on orienting exogenous and endogenous covert visual attention

Olaf Blanke, Mariia Kaliuzhna, Andrea Serino, Steve Michel Berger

Recent research highlights the overwhelming role of vestibular information for higher order cognition. Central to body perception, vestibular cues provide information about self-location in space, self-motion versus object motion, and modulate the percepti ...

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

Michael Herzog, Olaf Blanke, Maya Roinishvili, Roy Salomon, Mariia Kaliuzhna, Ophélie Gladys Favrod, 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 ...

Optimal visuo-vestibular integration for self-motion perception in patients with unilateral vestibular loss

Olaf Blanke, Mariia Kaliuzhna, Steven Gale

Unilateral vestibular loss (UVL) is accompanied by deficits in processing of visual and vestibular self-motion cues. The present study examined whether multisensory integration of these two types of information is, nevertheless, intact in such patients. Pa ...

Interoceptive signals impact visual processing: Cardiac modulation of visual body perception

Olaf Blanke, Fosco Bernasconi, Roberta Ronchi, Christian Pfeiffer, Mariia Kaliuzhna, Javier Bello Ruiz

Multisensory perception research has largely focused on exteroceptive signals, but recent evidence has revealed the integration of exteroceptive signals with interoceptive information. Such research revealed that heartbeat signals affect sensory (e.g., vis ...

Multisensory Integration in Self Motion Perception

Olaf Blanke, Mariia Kaliuzhna

Self motion perception involves the integration of visual, vestibular, somatosensory and motor signals. This article reviews the findings from single unit electrophysiology, functional and structural magnetic resonance imaging and psychophysics to present ...

Multisensory effects on somatosensation: a trimodal visuo-vestibular-tactile interaction

Olaf Blanke, Bruno Herbelin, Mariia Kaliuzhna

Vestibular information about self-motion is combined with other sensory signals. Previous research described both visuo-vestibular and vestibular-tactile bilateral interactions, but the simultaneous interaction between all three sensory modalities has not ...

Balancing awareness: Vestibular signals modulate visual consciousness in the absence of awareness

Olaf Blanke, Bruno Herbelin, Roy Salomon, Mariia Kaliuzhna

The processing of visual and vestibular information is crucial for perceiving self-motion. Visual cues, such as optic flow, have been shown to induce and alter vestibular percepts, yet the role of vestibular information in shaping visual awareness remains ...

Learning to integrate contradictory multisensory self-motion cue pairings

Olaf Blanke, Mariia Kaliuzhna, Steven Gale, Sunho Lee

Humans integrate multisensory information to reduce perceptual uncertainty when perceiving the world and self. Integration fails, however, if a common causality is not attributed to the sensory signals, as would occur in conditions of spatiotemporal discre ...

Balancing the Self

Mariia Kaliuzhna

The vestibular system is composed of otolith organs and semi-circular canals that encode linear and angular accelerations, as well as the position of the head with respect to gravity. Thus, the detection of self-motion, the distinction between self- and ob ...
