Out-of-body illusion induced by visual-vestibular stimulation

Olaf Blanke, Bruno Herbelin, Sophie Jacqueline Andrée Betka, Florian Lance, Hsin-Ping Wu, Estelle Nakul

Out-of-body experiences (OBEs) are characterized by the subjective feeling of being located outside one's physical body and perceiving one's own body from an elevated perspective looking downwards. OBEs have been correlated with abnormal integration of bod ...

Common and distinct brain networks of autoscopic phenomena

Olaf Blanke, Lukas Heydrich, Eva Blondiaux

Objective Autoscopic phenomena (AP) are illusory own body reduplications characterized by the visual perception of a second own body in extrapersonal space, and include three main forms: autoscopic hallucination (AH), heautoscopy (HAS) and out-of-body-expe ...

The Dimension of the Body in Higher Education: Matrix of Meanings in Students’ Diaries

Simon Nessim Henein, Ramiro Tau

In this paper, we attempt to show some consequences of bringing the body back into higher education, through the use of performing arts in the curricular context of scientific programs. We start by arguing that dominant traditions in higher education repro ...

Method and system for creating an out-of-body experience

Olaf Blanke, Bruno Herbelin, Giulio Rognini, Florian Lance, Simon Gallo

A computer-implemented method for inducing an Out of Body Experience (OBE) in a user through an augmented/virtual reality (AR/VR) system, the OBE including an exit state and a disembodiment state, the method comprising the steps of (a) changing the user vi ...

Autoscopic phenomena as an atypical psychiatric presentation of Huntington's disease: A case report including longitudinal clinical and neuroimaging data

Olaf Blanke

Huntington's disease (HD) is a monogenetic neurodegenerative disease prototypically characterized by the progressive presentation of motor abnormalities, cognitive deterioration and neuropsychiatric symptoms. Even when the disorder is diagnosed based on th ...

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 ...

Hallucination Engineering: From Neuroscience Robotics to Hallucinations in Health and Disease

Eva Blondiaux

My thesis focuses on a psychotic symptom called the presence hallucination (PH). PHs are defined as the false perception that someone is nearby when no one is actually present. PHs can occur in various populations, ranging from healthy subjects (when expos ...

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

Olaf Blanke, Mariia Kaliuzhna, Petr Grivaz

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 ...

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 ...

Partial and full own-body illusions of epileptic origin in a child with right temporoparietal epilepsy

Olaf Blanke, Lukas Heydrich

Partial and full own-body illusions of neurological origin have been claimed crucial to understand the contribution of bodily experience and perception to self-consciousness. Whereas partial body illusions are relatively common and well defined, much less ...

The timing of temporoparietal and frontal activations during mental own body transformations from different visuospatial perspectives

Olaf Blanke

The perspective from where the world is perceived is an important aspect of the bodily self and may break down in neurological conditions such as out-of-body experiences (OBEs). These striking disturbances are characterized by disembodiment, an external pe ...

Deficient mental own-body imagery in a neurological patient with out-of-body experiences due to cannabis use

Olaf Blanke

In the present work, we report repeated out-of-body experiences (OBEs) in a patient with tetraplegia and severe somatosensory loss due to multiple sclerosis and predominant involvement of the cervical spinal cord. OBEs were experienced on a daily basis and ...

A putative implication for fronto-parietal connectivity in out-of-body experiences

Olaf Blanke, Christine Mohr

Self-processing has been related to the prefrontal cortex (PFC) and the temporo-parietal junction (TPJ) as well as to their connectivity. So far, out-of-body experiences (OBEs), impressive transient deviations of intact bodily self-integration, could be as ...

The vestibular component in out-of-body experiences: a computational approach

Olaf Blanke

Neurological evidence suggests that disturbed vestibular processing may play a key role in triggering out-of-body experiences (OBEs). Little is known about the brain mechanisms during such pathological conditions, despite recent experimental evidence that ...

Out-of-body experiences: false climbs in a supine position?

Olaf Blanke

Out-of-body experiences (OBEs) are illusions, where people experience themselves as being located outside their physical body and often flying or floating at an elevated location. Here, we propose that the flying and floating in OBEs can be explained as th ...

Video ergo sum: manipulating bodily self-consciousness

Olaf Blanke, Ravi Tej Sai Giridhar Tadi

Humans normally experience the conscious self as localized within their bodily borders. This spatial unity may break down in certain neurological conditions such as out-of-body experiences, leading to a striking disturbance of bodily self-consciousness. On ...

Clinical neuroimaging in epileptic patients with autoscopic hallucinations and out-of-body experiences

Olaf Blanke

Autoscopic phenomena are complex illusory perceptions of one's body during which human subjects experience a second own body or double in their environment. Autoscopic phenomena most commonly refer tovisual doubles, although doubles may also be felt or hea ...

Functional and neural mechanisms of embodiment: importance of the vestibular system and the temporal parietal junction

Olaf Blanke

Embodiment, the sense of being localized within one's physical body, is a fundamental aspect of the self. Recent research shows that self and body processing as well as embodiment require distinct brain mechanisms. Here, we review recent clinical and neuro ...

The demystification of autoscopic phenomena: experimental propositions

Olaf Blanke, Christine Mohr

Autoscopic phenomena (AP) are rare, illusory visual experiences during which the subject has the impression of seeing a second own body in extrapersonal space. AP consist of out-of-body experience, autoscopic hallucination, and heautoscopy. Recent neurolog ...

The out-of body experience: precipitating factors and neural correlates

Olaf Blanke

Out-of-body experiences (OBEs) are defined as experiences in which a person seems to be awake and sees his body and the world from a location outside his physical body. More precisely, they can be defined by the presence of the following three phenomenolog ...
