Somatosensory-visual effects in visual biological motion perception

Olaf Blanke, Kim Do, Nathan Quentin Faivre, Manuel Mercier, Pierre Progin, Wenwen Chang

Social cognition is dependent on the ability to extract information from human stimuli. Of those, patterns of biological motion (BM) and in particular walking patterns of other humans, are prime examples. Although most often tested in isolation, BM outside ...

Anatomically and functionally distinct thalamocortical inputs to primary and secondary mouse whisker somatosensory cortices

Carl Petersen, Georgios Foustoukos, Sami El-Boustani, Berat Semihcan Sermet

Subdivisions of mouse whisker somatosensory thalamus project to cortex in a region-specific and layer-specific manner. However, a clear anatomical dissection of these pathways and their functional properties during whisker sensation is lacking. Here, we us ...

Biomimetic Intraneural Sensory Feedback Enhances Sensation Naturalness, Tactile Sensitivity, and Manual Dexterity in a Bidirectional Prosthesis

Silvestro Micera, Giulio Rognini, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Giacomo Valle, Francesco Iberite

Peripheral intraneural stimulation can provide tactile information to amputees. However, efforts are still necessary to identify encoding strategy eliciting percepts that are felt as both natural and effective for prosthesis control. Here we compared the n ...

Improving the control of prosthetic hands with tactile sensing

Sylvain Calinon, Noémie Laure Gwendoline Jaquier

Despite recent advances in prostheses, intuitive and robust control of poly-articulated prosthetic hands remains an unsolved problem. The TACT-HAND project aims at providing hand amputees with improved dexterous capabilities by exploiting tactile sensing a ...

Peripersonal Space: An Index of Multisensory Body–Environment Interactions in Real, Virtual, and Mixed Realities

Olaf Blanke, Andrea Serino, Bruno Herbelin, Fosco Bernasconi, Jean-Paul Noel, Javier Bello Ruiz, Elisa Canzoneri, Robin Mange, Elisa Pellencin

Human–environment interactions normally occur in the physical milieu and thus by medium of the body and within the space immediately adjacent to and surrounding the body, the peripersonal space (PPS). However, human interactions increasingly occur with or ...

Unconscious integration of multisensory bodily inputs in the peripersonal space shapes bodily self-consciousness

Olaf Blanke, Andrea Serino, Roy Salomon, Nathan Quentin Faivre, Jean-Paul Noel, Marta Lukowska

Recent studies have highlighted the role of multisensory integration as a key mechanism of self-consciousness. In particular, integration of bodily signals within the peripersonal space (PPS) underlies the experience of the self in a body we own (self-iden ...

Multisensory effects on somatosensation: a trimodal visuo-vestibular-tactile interaction

Olaf Blanke, Bruno Herbelin, Mariia Kaliuzhna

Vestibular information about self-motion is combined with other sensory signals. Previous research described both visuo-vestibular and vestibular-tactile bilateral interactions, but the simultaneous interaction between all three sensory modalities has not ...

Soft Pneumatic Actuator Skin with Piezoelectric Sensors for Vibrotactile Feedback

Jamie Paik, Harshal Arun Sonar

The latest wearable technologies demand more intuitive and sophisticated interfaces for communication, sensing, and feedback closer to the body. Evidently, such interfaces require flexibility and conformity without losing their functionality even on rigid ...

Dexterous grasping under shape uncertainty

Aude Billard, Miao Li

An important challenge in robotics is to achieve robust performance in object grasping and manipulation, dealing with noise and uncertainty. This paper presents an approach for addressing the performance of dexterous grasping under shape uncertainty. In ou ...

Full body action remapping of peripersonal space: The case of walking

Olaf Blanke, Hervé Lissek, Andrea Serino, Patrick Marmaroli, Jean-Paul Noel, Petr Grivaz

The space immediately surrounding the body, i.e. peripersonal space (PPS), is represented by populations of multisensory neurons, from a network of premotor and parietal areas, which integrate tactile stimuli from the body’s surface with visual or auditory ...

A flexible multimodal tactile display for delivering shape and material information

Hannes Bleuler, Simon Gallo

The growing complexity of telemanipulation tasks calls for increased realism and intuitiveness of the interaction between the user and the master control. Humans perceive multiple haptic features of an object such as its stiffness, temperature, and shape, ...

Crossing the hands increases illusory self-touch

Olaf Blanke, Roy Salomon, Giulio Rognini, Polona Pozeg

Manipulation of hand posture, such as crossing the hands, has been frequently used to study how the body and its immediately surrounding space are represented in the brain. Abundant data show that crossed arms posture impairs remapping of tactile stimuli f ...

Combining proprioception and touch to compute spatial information

Elisa Canzoneri

Localising a tactile stimulus in egocentric space involves integrating information from skin receptors with proprioceptive inputs about body posture. We investigated whether body posture automatically influences tactile spatial judgements, even when it is ...

Learning of Grasp Adaptation through Experience and Tactile Sensing

Aude Billard, Miao Li

To perform robust grasping, a multi-fingered robotic hand should be able to adapt its grasping configuration, i.e., how the object is grasped, to maintain the stability of the grasp. Such a change of grasp configuration is called grasp adaptation and it de ...

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

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

Expanding the primate body schema in sensorimotor cortex by virtual touches of an avatar

Hannes Bleuler, Miguel Nicolelis, Solaiman Shokur

The brain representation of the body, called the body schema, is susceptible to plasticity. For instance, subjects experiencing a rubber hand illusion develop a sense of ownership of a mannequin hand when they view it being touched while tactile stimuli ar ...

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

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

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 ...

Extending the body to virtual tools using a robotic surgical interface: evidence from the crossmodal congruency task

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

The effects of real-world tool use on body or space representations are relatively well established in cognitive neuroscience. Several studies have shown, for example, that active tool use results in a facilitated integration of multisensory information in ...

Leg muscle vibration modulates bodily self-consciousness: integration of proprioceptive, visual, and tactile signals

Olaf Blanke, Jane Aspell, Estelle Palluel

Behavioral studies have used visuo-tactile conflicts between a participant's body and a visually presented fake or virtual body to investigate the importance of bodily perception for self-consciousness (bodily self-consciousness). Illusory self-identificat ...

Seeing the body modulates audiotactile integration

Olaf Blanke, Jane Aspell, Bigna Lenggenhager

Audiotactile integration has been studied using various experimental setups but so far crossmodal congruency effects (CCEs) have not been found for tactile targets paired with auditory distractors. In the present study we investigated whether audiotactile ...
