Bilateral Rolandic operculum processing underlying heartbeat awareness reflects changes in bodily self-consciousness

Bruno Herbelin, Roberto Martuzzi, Olaf Blanke, Javier Bello Ruiz, Roy Salomon, Maria Laura Blefari, Andrea Serino

Exteroceptive bodily signals (including tactile, proprioceptive and visual signals) are important information contributing to self-consciousness. Moreover, prominent theories proposed that visceral signals about internal bodily states are equally or even m ...

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

Olaf Blanke, Manuel Mercier

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 ...

Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation

Roberto Martuzzi, Olaf Blanke, Michel Akselrod, Wietske Van der Zwaag, Giulio Rognini, Roy Salomon, Maria Laura Blefari, Andrea Serino, Elisa Canzoneri

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual li ...

Anatomical and functional properties of the foot and leg representation in areas 3b, 1 and 2 of primary somatosensory cortex in humans: A 7T fMRI study

Roger Gassert, Roberto Martuzzi, Olaf Blanke, Michel Akselrod, Wietske Van der Zwaag, Andrea Serino

Primary somatosensory cortex (S1) processes somatosensory information and is composed of multiple subregions. In particular, tactile information from the skin is encoded in three subregions, namely Brodmann areas (BAs) 3b, 1 and 2, with each area represent ...

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

Olaf Blanke, Javier Bello Ruiz, Roy Salomon, Nathan Quentin Faivre, Fosco Bernasconi, Michele Scandola, 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 and distinct brain regions processing multisensory bodily signals for peripersonal space and body ownership

Olaf Blanke, Petr Grivaz, Andrea Serino

We take the feeling that our body belongs to us for granted. However, recent research has shown that it is possible to alter the subjective sensation of body ownership (BO) by manipulating multisensory bodily inputs. Several frontal and parietal regions ar ...

Interferences between breathing, experimental dyspnoea and bodily self-consciousness

Bruno Herbelin, Olaf Blanke, Javier Bello Ruiz, Elisa Canzoneri, Etienne Allard

Dyspnoea, a subjective experience of breathing discomfort, is a most distressing symptom. It implicates complex cortical networks that partially overlap with those underlying bodily self-consciousness, the experience that the body is one's own within a giv ...

Performance monitoring for brain-computer-interface actions

Olaf Blanke, Steven Gale, Olivia Gozel, Aaron Schurger

When presented with a difficult perceptual decision, human observers are able to make metacognitive judgements of subjective certainty. Such judgements can be made independently of and prior to any overt response to a sensory stimulus, presumably via inter ...

Distinct vestibular effects on early and late somatosensory cortical processing in humans

Olaf Blanke, Christian Pfeiffer, Michiel van Elk, Fosco Bernasconi

In non-human primates several brain areas contain neurons that respond to both vestibular and somatosensory stimulation. In humans, vestibular stimulation activates several somatosensory brain regions and improves tactile perception. However, less is known ...

Quantifying the role of motor imagery in brain-machine interfaces

Hannes Bleuler, Olaf Blanke, Silvia Marchesotti, Andrea Serino, Michela Bassolino

Despite technical advances in brain machine interfaces (BMI), for as-yet unknown reasons the ability to control a BMI remains limited to a subset of users. We investigate whether individual differences in BMI control based on motor imagery (MI) are related ...

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

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

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 ...

Transient Modulations of Neural Responses to Heartbeats Covary with Bodily Self-Consciousness

Olaf Blanke, Javier Bello Ruiz, Christian Pfeiffer, Roy Salomon, Fosco Bernasconi, Hyeongdong Park

Recent research has investigated self-consciousness associated with the multisensory processing of bodily signals (e.g., somatosensory, visual, vestibular signals), a notion referred to as bodily self-consciousness, and these studies have shown that the ma ...

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 ...

Visual gravity contributes to subjective first-person perspective

Bruno Herbelin, Olaf Blanke, Petr Grivaz, Christian Pfeiffer, Andrea Serino

A fundamental component of conscious experience involves a first-person perspective (1PP), characterized by the experience of being a subject and of being directed at the world. Extending earlier work on multisensory perceptual mechanisms of 1PP, we here a ...

Cognetics: Robotic Interfaces for the Conscious Mind

Olaf Blanke, Giulio Rognini

Cognetics joins the cognitive neuroscience of bodily awareness with robotics to study, control, and enhance perception, cognition, and consciousness. We highlight robot-controlled bodily perception, conscious states, and social interactions and sketch how ...

Changing motor perception by sensorimotor conflicts and body ownership

Olaf Blanke, Michiel van Elk, Roy Salomon, Joan Llobera Mahy, Natalia Fernandez

Experimentally induced sensorimotor conflicts can result in a loss of the feeling of control over a movement (sense of agency). These findings are typically interpreted in terms of a forward model in which the predicted sensory consequences of the movement ...

Device, System, and Method for Robot-Controlled Induction of the Feeling of Human Presence

Olaf Blanke, Masayuki Hara, Giulio Rognini

A method for inducing the feeling of a presence (FoP) in a subject by using a master-slave robotic system, the method including the steps of altering a visual perception of a surrounding environment of the subject, connecting the subject with a robotic mas ...

Enhanced discriminability for nonbiological motion violating the two-thirds power law

Olaf Blanke, Laurène Véronique Vuillaume, Roy Salomon, Nathan Quentin Faivre

The two-thirds power law describes the relationship between velocity and curvature in human motor movements. Interestingly, this motor law also affects visual motion perception, in which stimuli moving according to the two-thirds power law are perceived to ...

The Insula Mediates Access to Awareness of Visual Stimuli Presented Synchronously to the Heartbeat

Bruno Herbelin, Olaf Blanke, Rémi Martet, Javier Bello Ruiz, Jonathan Dönz, Roy Salomon, Roberta Ronchi, Nathan Quentin Faivre

The processing of interoceptive signals in the insular cortex is thought to underlie self-awareness. However, the influence of interoception on visual awareness and the role of the insular cortex in this process remain unclear. Here, we show in a series of ...

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

Bruno Herbelin, Olaf Blanke, 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 ...
