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 ...

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

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

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, 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 ...

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

Olaf Blanke, Steven Gale, Mariia Kaliuzhna

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

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

Bruno Herbelin, Olaf Blanke, 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

Bruno Herbelin, Olaf Blanke, Mariia Kaliuzhna, Roy Salomon

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, Steven Gale, Mariia Kaliuzhna, 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 ...

Out-of-Body Experiences and Other Complex Dissociation Experiences in a Patient with Unilateral Peripheral Vestibular Damage and Deficient Multisensory Integration

Olaf Blanke, Petr Grivaz, Mariia Kaliuzhna

Out-of-body experiences (OBEs) are illusory perceptions of one's body from an elevated disembodied perspective. Recent theories postulate a double disintegration process in the personal (visual, proprioceptive and tactile disintegration) and extrapersonal ...

Disabling conditional inferences: An EEG study

Mariia Kaliuzhna

Although the Modus Ponens inference is one of the most basic logical rules, decades of conditional reasoning research show that it is often rejected when people consider stored background knowledge about potential disabling conditions. In the present study ...

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 ...

Belief Revision and Delusions: How Do Patients with Schizophrenia Take Advice?

Mariia Kaliuzhna

The dominant cognitive model that accounts for the persistence of delusional beliefs in schizophrenia postulates that patients suffer from a general deficit in belief revision. It is generally assumed that this deficit is a consequence of impaired reasonin ...
