Neuroscience robotics to investigate multisensory integration and bodily awareness

Julio Duenas, Olaf Blanke, Roger Gassert, Dominique Chapuis, Roberto Martuzzi, Christian Pfeiffer, Silvio Ionta

Humans experience the self as localized within their body. This aspect of bodily self-consciousness can be experimentally manipulated by exposing individuals to conflicting multisensory input, or can be abnormal following focal brain injury. Recent technol ...

Virtual Reality platform for functional Magnetic Resonance Imaging in Ecologically valid conditions

Olaf Blanke, Bruno Herbelin, Baptiste Gauthier, Louis Philippe Albert

Functional magnetic resonance Brain Imaging (fMRI) is a key non-invasive imaging technique for the study of human brain activity. Its millimetric spatial resolution is at the cost of several constraints: participants must remain static and experience artif ...

Breathing is coupled with voluntary initiation of mental imagery

Olaf Blanke, Oliver Alan Kannape, Hyeongdong Park

Previous research has suggested that bodily signals from internal organs are associated with diverse cortical and subcortical processes involved in sensory-motor functions, beyond homeostatic reflexes. For instance, a recent study demonstrated that the pre ...

How ageing shapes body and space representations: A comparison study between healthy young and older adults

Olaf Blanke, Andrea Serino, Michela Bassolino, Matteo Franza

To efficiently interact with the external world, the brain needs to represent the size of the involved body parts - body representations (BR) - and the space around the body in which the interactions with the environment take place - peripersonal space rep ...

From multisensory integration in peripersonal space to bodily self-consciousness: from statistical regularities to statistical inference

Olaf Blanke, Andrea Serino

Integrating information across sensory systems is a critical step toward building a cohesive representation of the environment and one's body, and as illustrated by numerous illusions, scaffolds subjective experience of the world and self. In the last year ...

Subjective mental time: the functional architecture of projecting the self to past and future

Olaf Blanke, Silvio Ionta

Human experience takes place in the line of mental time (MT) created through 'self-projection' of oneself to different time-points in the past or future. Here we manipulated self-projection in MT not only with respect to one's life events but also with res ...

Size and Viewpoint of an Embodied Virtual Body Affect the Processing of Painful Stimuli

Olaf Blanke, Joan Llobera Mahy

Looking at one's own body might induce visual analgesia. However, the cognitive and physiological mechanisms underlying such visual analgesia are unknown. Because body and pain representations in the brain are multisensory, and have been reported to partia ...

Apraxia: a review

Olaf Blanke, Aude Billard, Biljana Petreska von Ritter-Zahony

Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that is difficult to assess or interpret. In this chapter, we review the current taxonomies of apraxia and related cognitive and neuro ...

Congruent Visuo-Tactile Feedback Facilitates the Extension of Peripersonal Space

Olaf Blanke, Hannes Bleuler, Michiel van Elk, Ali Sengül

Effective tool use relies on the integration of multisensory signals related to one's body and the tool. It has been shown that active tool use results in an extension of peripersonal space, i. e., the space directly surrounding the human body. In the pres ...

Bodily self-consciousness and its disorders, The Parietal Lobe

Olaf Blanke, Hyeongdong Park, Roberta Ronchi

Research in clinical and human neuroscience indicates that important brain mechanisms of self-consciousness are based on the integration of multisensory bodily signals (i.e., bodily self-consciousness: BSC), including signals coming from outside our body ( ...

Embodiment in episodic memory through premotor-hippocampal coupling

Olaf Blanke, Bruno Herbelin, Jevita Potheegadoo, Baptiste Gauthier, Nathalie Heidi Meyer, Florian Lance, Mariana Babo Rebelo, Sara Stampacchia, Juliette Marie Elise Jocelyne Boscheron

Episodic memory (EM) allows us to remember and relive past events and experiences and has been linked to cortical-hippocampal reinstatement of encoding activity. While EM is fundamental to establish a sense of self across time, this claim and its link to t ...

Right insular damage decreases heartbeat awareness and alters cardio-visual effects on bodily self-consciousness

Olaf Blanke, Bruno Herbelin, Javier Bello Ruiz, Roberta Ronchi

Recent evidence suggests that multisensory integration of bodily signals involving exteroceptive or interoceptive information modulates bodily aspects of self-consciousness such as self-identification and self-location. In the so-called full body illusion ...

The 'intrinsic' system in the human cortex and self-projection: a data driven analysis

Olaf Blanke

Information received by the human cortex is supplied by two main sources: extrinsic stimuli delivered by the external environment and intrinsic information regarding the body and self. We reanalyzed electrophysiological data involving the same external sti ...

Vestibular-Somatosensory Interactions: Effects of Passive Whole-Body Rotation on Somatosensory Detection

Olaf Blanke, Bruno Herbelin, 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 ...

Visual consciousness and bodily self-consciousness

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon

Purpose of review: In recent years, consciousness has become a central topic in cognitive neuroscience. This review focuses on the relation between bodily self-consciousness - the feeling of being a subject in a body - and visual consciousness - the subjec ...

Meditation in the third-person perspective modulates minimal self and heartbeat-evoked potentials

Hang Yang, Olaf Blanke, Bruno Herbelin, Loup Vuarnesson

Experienced meditation practitioners often report altered states of their sense of self, including decentering and distancing the self from the body and one's current concerns. Altered states of the sense of self, such as disembodiment and distancing of th ...

You or me? Disentangling perspectival, perceptual, and integrative mechanisms in heterotopagnosia

Olaf Blanke, Bruno Herbelin, Andrea Serino, Michela Bassolino

Heterotopagnosia-without-Autotopagnosia (HwA) is characterized by the incapacity to point to body parts on others, but not on one's own body. This has been classically interpreted as related to a self-other distinction, with impaired visual representations ...

Dorsal and ventral stream contributions to form-from-motion perception in a patient with form-from motion deficit: a case report

Olaf Blanke

The main model of visual processing in primates proposes an anatomo-functional distinction between the dorsal stream, specialized in spatio-temporal information, and the ventral stream, processing essentially form information. However, these two pathways a ...

Behavioural, modeling, and electrophysiological evidence for supramodality in human metacognition

Olaf Blanke, Nathan Quentin Faivre

Human metacognition, or the capacity to introspect on one's own mental states, has been mostly characterized through confidence reports in visual tasks. A pressing question is to what extent results from visual studies generalize to other domains. Answerin ...

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 ...
