Increased functional connectivity of the intraparietal sulcus underlies the attenuation of numerosity estimations for self-generated words

Michael Eric Anthony Pereira, Olaf Blanke, Giulio Rognini, Nathan Quentin Faivre, Jevita Potheegadoo, Giedre Stripeikyte

Previous studies have shown that self-generated stimuli in auditory, visual, and somatosensory domains are attenuated, producing decreased behavioral and neural responses compared to the same stimuli that are externally generated. Yet, whether such attenua ...

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- ...

Flight of mind: Sensorimotor and multisensory embodiment with aviation robotics, flight simulator, and virtual reality

Myeong Seop Song

Normally, humans experience an 'I' as residing in one's body and as the agent of one's actions. In other words, the self is experienced as being inside the body (self-location), as having a body (self-identification), and as being able to control the perso ...

Dissecting self-voice perception: From bone conduction to robotically-induced self-other voice misattribution in healthy listeners

Pavo Orepic

Inspired by the prominent theory suggesting that auditory-verbal hallucinations (AVH) - the sensation of hearing voices without present speakers - arise as misattribution of inner speech towards external agents, my thesis revolved around self-voice percept ...

Visual Distortions in 360-degree videos (Dataset)

Pascal Frossard, Francesca De Simone, Roberto Gerson De Albuquerque Azevedo

Here we catalog, visually demonstrate, and discuss the main causes of commonly encountered visual distortions into current 360-degree video processing pipelines. The main goal of the samples in this dataset is to demonstrate the visual distortions discusse ...

Audio-visual sensory deprivation degrades visuo-tactile peri-personal space

Hervé Lissek, Olaf Blanke, Isabella Maria Pasqualini, Jean-Paul Noel, Andrea Serino, Hyeongdong Park

Self-perception is scaffolded upon the integration of multisensory cues on the body, the space surrounding the body (i.e., the peri-personal space; PPS), and from within the body. We asked whether reducing information available from external space would ch ...

The Architectonic Experience of Body and Space in Augmented Interiors

Olaf Blanke, Isabella Maria Pasqualini, Maria Laura Blefari, Andrea Serino

The environment shapes our experience of space in constant interaction with the body. Architectonic interiors amplify the perception of space through the bodily senses; an effect also known as embodiment. The interaction of the bodily senses with the space ...

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 ...

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 ...

Exploring the pathological interaction between LRRK2 and alpha-synuclein : two key genes implicated in Parkinson's disease

Alessandra Musso

Parkinson’s disease (PD) is the most common age-related neurodegenerative movement disorder that affects 1-2% of the general population over the age of 65 and rising to 4-5% over 80 years of age. It is estimated that 6.3 million people worldwide have Parki ...

Visual capture and the experience of having two bodies – Evidence from two different virtual reality techniques

Bruno Herbelin, Olaf Blanke, Jane Aspell, Lukas Heydrich

In neurology and psychiatry the detailed study of illusory own body perceptions has suggested close links between bodily processing and self-consciousness. One such illusory own body perception is heautoscopy where patients have the sensation of being redu ...

Distinct illusory own-body perceptions caused by damage to posterior insula and extrastriate cortex

Olaf Blanke, Lukas Heydrich

Recent research in cognitive neuroscience using virtual reality, robotic technology and brain imaging has linked self-consciousness to the processing and integration of multisensory bodily signals. This work on bodily self-consciousness has implicated the ...

"Self pop-out": agency enhances self-recognition in visual search

Olaf Blanke, Oliver Alan Kannape, Roy Salomon, Joan Llobera Mahy, Mei Ling Melanie Lim

In real-life situations, we are often required to recognize our own movements among movements originating from other people. In social situations, these movements are often correlated (for example, when dancing or walking with others) adding considerable d ...

"Seeing" and "feeling" architecture: how bodily self-consciousness alters architectonic experience and affects the perception of interiors

Olaf Blanke, Isabella Maria Pasqualini, Joan Llobera Mahy

Over the centuries architectural theory evolved several notions of embodiment, proposing in the nineteenth and twentieth century that architectonic experience is related to physiological responses of the observer. Recent advances in the cognitive neuroscie ...

Full body illusion is associated with widespread skin temperature reduction

Roger Gassert, Olaf Blanke, Christian Pfeiffer, Roy Salomon, Mei Ling Melanie Lim

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 ...

Seeing and identifying with a virtual body decreases pain perception

Roland von Känel, Olaf Blanke, Bigna Lenggenhager

Pain and the conscious mind (or the self) are experienced in our body. Both are intimately linked to the subjective quality of conscious experience. Here, we used virtual reality technology and visuo-tactile conflicts in healthy subjects to test whether ex ...

The Rhythm of Bodily Self-Consciousness

Pär Halje

Recent philosophical, psychological and neuroscientific theories suggest that bodily experience is crucial for the phenomenology of selfhood (i.e. the experience of 'being someone'). In this thesis I have shown that two essential aspects of bodily self-con ...

Illusory own body perceptions: case reports and relevance for bodily self-consciousness

Olaf Blanke, Sebastian Dieguez Falcon, Lukas Heydrich

Neurological disorders of body representation have for a long time suggested the importance of multisensory processing of bodily signals for self-consciousness. One such group of disorders--illusory own body perceptions affecting the entire body--has been ...
