Duration and not strength of activation in temporo-parietal cortex positively correlates with schizotypy

Olaf Blanke, Christine Mohr

Impaired self- and own body processing in patients with schizophrenia and individuals along the schizophrenia spectrum have been associated with dysfunctional cortical activation at the temporo-parietal junction. Here we investigated whether strength or du ...

The neuropsychology and neuroanatomy of reduplicative paramnesia

Olaf Blanke

Reduplicative paramnesia refers to the delusional belief that there are identical places in different locations. In this case-control study we investigated the clinical, phenomenological, neuropsychological and neuroanatomical data of eleven patients with ...

Visual hallucinations in Parkinson's disease are associated with deficits in social perception

Olaf Blanke, Fosco Bernasconi, Jevita Potheegadoo, Louis Philippe Albert, Neza Vehar

Most structured visual hallucinations (VH) in Parkinson's disease (PD) involve animate-social objects, yet current theories fail to account for the prominent social component of VH in PD. To study social perception in PD patients with VH in a behavioral ta ...

Body and peripersonal space representations in chronic stroke patients with upper limb motor deficits

Olaf Blanke, Silvestro Micera, Andrea Serino, Michela Bassolino, Elisa Canzoneri, Andrea Crema, Matteo Franza

The continuous stream of multisensory information between the brain and the body during body-environment interactions is crucial to maintain the updated representation of the perceived dimensions of body parts (metric body representation) and the space aro ...

Full body illusion is associated with widespread skin temperature reduction

Olaf Blanke, Roger Gassert, Roy Salomon, Christian Pfeiffer

A central feature of our consciousness is the experience of the self as a unified entity residing in a physical body, termed bodily self-consciousness. This phenomenon includes aspects such as the sense of owning a body (also known as body ownership) and h ...

Robotically-induced auditory-verbal hallucinations: combining self-monitoring and strong perceptual priors

Olaf Blanke, Fosco Bernasconi, Nathan Quentin Faivre, Pavo Orepic, Melissa Faggella

Background. Inducing hallucinations under controlled experimental conditions in nonhallucinating individuals represents a novel research avenue oriented toward understanding complex hallucinatory phenomena, avoiding confounds observed in patients. Audito ...

Interoception and Empathy Impact Perspective Taking

Olaf Blanke, Bruno Herbelin, Jane Aspell, Lukas Heydrich

Adopting the perspective of another person is an important aspect of social cognition and has been shown to depend on multisensory signals from one's own body. Recent work suggests that interoceptive signals not only contribute to own-body perception and s ...

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

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

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- ...

Leg muscle vibration modulates bodily self-consciousness: integration of proprioceptive, visual, and tactile signals

Olaf Blanke, Jane Aspell, Estelle Palluel

Behavioral studies have used visuo-tactile conflicts between a participant's body and a visually presented fake or virtual body to investigate the importance of bodily perception for self-consciousness (bodily self-consciousness). Illusory self-identificat ...

Subcortical correlates of consciousness with human single neuron recordings

Olaf Blanke, Fosco Bernasconi, Nathan Quentin Faivre, Michael Eric Anthony Pereira

Subcortical brain structures such as the basal ganglia or the thalamus are involved in regulating motor and cognitive behavior. However, their contribution to perceptual consciousness is still unclear, due to the inherent difficulties of recording subcorti ...

Influence of galvanic vestibular stimulation on egocentric and object-based mental transformations

Olaf Blanke

The vestibular system analyses angular and linear accelerations of the head that are important information for perceiving the location of one's own body in space. Vestibular stimulation and in particular galvanic vestibular stimulation (GVS) that allow a s ...

Multisensory Origin of the Subjective First-Person Perspective: Visual, Tactile, and Vestibular Mechanisms

Olaf Blanke, Roberto Martuzzi, Christian Pfeiffer, Valentin Marc Schmutz, Julio Duenas

In three experiments we investigated the effects of visuo-tactile and visuo-vestibular conflict about the direction of gravity on three aspects of bodily self-consciousness: self-identification, self-location, and the experienced direction of the first-per ...

Self-motion leads to mandatory cue fusion across sensory modalities

Olaf Blanke, Steven Gale

When perceiving properties of the world, we effortlessly combine multiple sensory cues into optimal estimates. Estimates derived from the individual cues are generally retained once the multisensory estimate is produced and discarded only if the cues stem ...

Conceptual processing is referenced to the experienced location of the self, not to the location of the physical body

Olaf Blanke, Bruno Herbelin, Andrea Serino, Elisa Canzoneri

We tested whether an experimentally induced change in the experienced location of the self by means of the Full Body Illusion (FBI) would impact high-level cognitive processing. In an implicit association task, participants saw a landscape where words, con ...

Self in time: imagined self-location influences neural activity related to mental time travel

Olaf Blanke

Conscious awareness of the self as continuous through time is attributed to the human ability to remember the past and to predict the future, a cogitation that has been called "mental time travel" (MTT). MTT allows one to re-experience one's own past by su ...

Self-grounded vision: hand ownership modulates visual location through cortical beta and gamma oscillations

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon, Fosco Bernasconi, Javier Bello Ruiz, Herberto Dhanis Pedro De Barros Camacho

Vision is known to be shaped by context, defined by environmental and bodily signals. In the Taylor illusion, the size of an afterimage projected on one's hand changes according to proprioceptive signals conveying hand position. Here, we assessed whether t ...

Common Recruitment of Angular Gyrus in Episodic Autobiographical Memory and Bodily Self-Consciousness

Olaf Blanke, Baptiste Gauthier, Petr Grivaz, Lucie Bréchet

Parietal cortex and adjacent parts of the temporal cortex have recently been associated with bodily self-consciousness (BSC). Similarly, growing evidence suggests that the lateral parietal cortex is crucial for the subjective aspects of episodic autobiogra ...

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

Olaf Blanke, Roy Salomon, Silvio Ionta, Roberto Martuzzi

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 ...

An invisible touch: Body-related multisensory conflicts modulate visual consciousness

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon, Javier Bello Ruiz

The majority of scientific studies on consciousness have focused on vision, exploring the cognitive and neural mechanisms of conscious access to visual stimuli. In parallel, studies on bodily consciousness have revealed that bodily (i.e. tactile, proprioce ...

Neural basis of embodiment: distinct contributions of temporoparietal junction and extrastriate body area

Olaf Blanke, Christine Mohr

Embodiment, the sense of being localized within one's physical body, is a fundamental aspect of the self. Recently, researchers have started to show that self and body processing require distinct brain mechanisms, suggesting two posterior brain regions as ...
