Crossmodal Congruency Enhances Performance of Healthy Older Adults in Visual-Tactile Pattern Matching

Friedhelm Christoph Hummel

One of the pivotal challenges of aging is to maintain independence in the activities of daily life. In order to adapt to changes in the environment, it is crucial to continuously process and accurately combine simultaneous input from different sensory syst ...

Enhanced audio-tactile multisensory interaction in a peripersonal task after echolocation

Andrea Serino

Peripersonal space (PPS) is created by a multisensory interaction between different sensory modalities and can be modified by experience. In this article, we investigated whether an auditory training, inside the peripersonal space area, can modify the PPS ...

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 ...

Balancing awareness: Vestibular signals modulate visual consciousness in the absence of awareness

Olaf Blanke, Bruno Herbelin, Roy Salomon, Mariia Kaliuzhna

The processing of visual and vestibular information is crucial for perceiving self-motion. Visual cues, such as optic flow, have been shown to induce and alter vestibular percepts, yet the role of vestibular information in shaping visual awareness remains ...

The wheelchair as a full-body tool extending the peripersonal space

Olaf Blanke, Andrea Serino, Elisa Canzoneri

Dedicated multisensory mechanisms in the brain represent peripersonal space (PPS), a limited portion of space immediately surrounding the body. Previous studies have illustrated the malleability of PPS representation through hand-object interaction, showin ...

Extending peripersonal space representation without tool-use: evidence from a combined behavioral-computational approach

Andrea Serino, Elisa Canzoneri

Stimuli from different sensory modalities occurring on or close to the body are integrated in a multisensory representation of the space surrounding the body, i.e., peripersonal space (PPS). PPS dynamically modifies depending on experience, e.g., it extend ...

Those are Your Legs: The Effect of Visuo-Spatial Viewpoint on Visuo-Tactile Integration and Body Ownership

Olaf Blanke, Polona Pozeg

Experiencing a body part as one's own, i.e., body ownership, depends on the integration of multisensory bodily signals (including visual, tactile, and proprioceptive information) with the visual top down signals from peripersonal space. Although it has bee ...

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, ...

Automatic Hand Phantom Map Detection Methods

Christian Enz, Claudio Bruschini, Jörn Justiz, Huaiqi Huang

Many amputees have maps of referred sensation from their missing hand on their residual limb (phantom maps). This skin area can serve as a target for providing amputees with tactile sensory feedback. Providing tactile feedback on the phantom map can improv ...

Force feedback facilitates multisensory integration during robotic tool use

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

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 ...

TOUCH: In-Memory Spatial Join by Hierarchical Data-Oriented Partitioning

Anastasia Ailamaki, Thomas Heinis, Farhan Tauheed

Efficient spatial joins are pivotal for many applications and particularly important for geographical information systems or for the simulation sciences where scientists work with spatial models. Past research has primarily focused on disk-based spatial jo ...

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

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

Tactile Feedback Improves Performance in a Palpation Task: Results in a VR-Based Testbed

Hannes Bleuler, Roger Gassert, Evren Samur, Laura Santos Carreras

Robotic surgery provides many benefits such as reduced invasiveness and increased dexterity. This comes at the cost of no direct contact between surgeon and patient This physical separation prevents surgeons from performing direct haptic exploration of tis ...

Duration and not strength of activation in temporo-parietal cortex positively correlates with schizotypy

Olaf Blanke, Christine Mohr

Impaired self- and own body processing in patients with schizophrenia and individuals along the schizophrenia spectrum have been associated with dysfunctional cortical activation at the temporo-parietal junction. Here we investigated whether strength or du ...

Spatio-temporal coupling of the electric and hemodynamic brain responses in humans

Roberto Martuzzi

Our comprehension of human brain functions and their dynamics has been dramatically improved by recent developments in non-invasive imaging techniques. These methods can be divided into two different categories, according to the nature of the measured sign ...

Perceptual aberrations impair mental own-body transformations

Olaf Blanke, Christine Mohr, Peter Andreas Brugger

Dysfunctional self and bodily processing have been reported from the schizophrenia spectrum. Here, the authors tested 72 students (40 women) to determine whether performance in a mental own-body transformation task relates to self-rated frequency of sponta ...
