Human finger somatotopy in areas 3b, 1, and 2: A 7T fMRI study using a natural stimulus

Roberto Martuzzi, Rolf Gruetter, Olaf Blanke, Juliane Farthouat, Wietske Van der Zwaag

To study the properties of human primary somatosensory (S1) cortex as well as its role in cognitive and social processes, it is necessary to noninvasively localize the cortical representations of the body. Being arguably the most relevant body parts for ta ...

Breathing and sense of self: Visuo-respiratory conflicts alter body self-consciousness (Reprint from Respiratory Physiology & Neurobiology, vol 203, pg 68-74)

Bruno Herbelin, Olaf Blanke

Bodily self-consciousness depends on the processing of interoceptive and exteroceptive signals. It can be disrupted by inducing signal conflicts. Breathing, at the crossroad between interoception and exteroception, should contribute to bodily self-consciou ...

Tapping into the brain: An ultra-high resolution investigation of the sensory-motor system using 7-Tesla fMRI

Rolf Gruetter, Olaf Blanke, Wietske Van der Zwaag, Roy Salomon

Posing for awareness: Proprioception modulates access to visual consciousness in a continuous flash suppression task

Bruno Herbelin, Olaf Blanke, Roy Salomon, Mei Ling Melanie Lim

The rules governing the selection of which sensory information reaches consciousness are yet unknown. Of our senses, vision is often considered to be the dominant sense, and the effects of bodily senses, such as proprioception, on visual consciousness are ...

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 ...

Visual and Force Feedback Time-Delays Change Telepresence: Quantitative Evidence from Crossmodal Congruecy Task

Hannes Bleuler, Olaf Blanke, Michiel van Elk

In the field of surgical robotics, it is difficult to find objective assessment techniques for evaluating telepresence. In this study we try to merge the concepts from cognitive neuroscience more specifically from the field of tool incorporation (embodimen ...

"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 ...

The effect of limb crossing and limb congruency on multisensory integration in peripersonal space for the upper and lower extremities

Olaf Blanke, Joachim Jean-Marie Forget, Michiel van Elk

The present study investigated how multisensory integration in peripersonal space is modulated by limb posture (i.e. whether the limbs are crossed or uncrossed) and limb congruency (i.e. whether the observed body part matches the actual position of one's l ...

Shared electrophysiology mechanisms of body ownership and motor imagery

Olaf Blanke, Nathaniel Evans

Although we feel, see, and experience our hands as our own (body or hand ownership), recent research has shown that illusory hand ownership can be induced for fake or virtual hands and may useful for neuroprosthetics and brain-computer interfaces. Despite ...

"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 ...

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

Roberto Martuzzi, Olaf Blanke, Christophe Lopez, Valentin Marc Schmutz, Christian Pfeiffer, 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 ...

Force feedback facilitates multisensory integration during robotic tool use

Hannes Bleuler, Olaf Blanke, Jane Aspell, Giulio Rognini, Ali Sengül, Michiel van Elk

The present study investigated the effects of force feedback in relation to tool use on the multisensory integration of visuo-tactile information. Participants learned to control a robotic tool through a surgical robotic interface. Following tool-use train ...

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 ...

Visuo-tactile integration and body ownership during self-generated action

Hannes Bleuler, Olaf Blanke, Jane Aspell, Giulio Rognini, Ali Sengül, Roy Salomon

Although there is increasing knowledge about how visual and tactile cues from the hands are integrated, little is known about how self-generated hand movements affect such multisensory integration. Visuo-tactile integration often occurs under highly dynami ...

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 ...

Turning Body and Self Inside Out. Visualized Heartbeats Alter Bodily Self-Consciousness and Tactile Perception

Bruno Herbelin, Olaf Blanke, Jane Aspell, Lukas Heydrich

Prominent theories highlight the importance of bodily perception for self-consciousness, but it is currently not known whether bodily perception is based on interoceptive or exteroceptive signals or on integrated signals from these anatomically distinct sy ...

Anatomically plausible illusory posture affects mental rotation of body parts

Olaf Blanke, Silvio Ionta, Anna Sforza, Mariko Funato

During mental rotation (MR) of body parts, people internally simulate the movement of their corresponding body segments. These sensory-motor mechanisms render MR sensitive to proprioceptive information (e.g., posture). Similar mechanisms can alter illusory ...

Digit somatotopy in the human cerebellum: A 7T fMRI study

Roberto Martuzzi, Rolf Gruetter, Olaf Blanke, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Remy Kusters

The representation of the human body in the human cerebellum is still relatively unknown, compared to the well-studied homunculus in the primary somatosensory cortex. The investigation of the body representation in the cerebellum and its somatotopic organi ...

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 ...
