p Robotically-induced hallucination triggers subtle changes in brain network transitions

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Giulio Rognini, Thomas William Arthur Bolton, Nathan Quentin Faivre, Eva Blondiaux, Herberto Dhanis Pedro De Barros Camacho

The perception that someone is nearby, although nobody can be seen or heard, is called presence hallucination (PH). Being a frequent hallucination in patients with Parkinson's disease, it has been argued to be indicative of a more severe and rapidly advanc ...

Neural signatures of visuo-motor integration during human-robot interactions

Olaf Blanke, Hannes Bleuler, Giulio Rognini, Fosco Bernasconi, Silvia Marchesotti

Visuo-motor integration shapes our daily experience and underpins the sense of feeling in control over our actions. The last decade has seen a surge in robotically and virtually mediated interactions, whereby bodily actions ultimately result in an artifici ...

Breathing affects self-other voice discrimination in a bodily state associated with somatic passivity

Olaf Blanke, Giulio Rognini, Nathan Quentin Faivre, Hyeongdong Park, Pavo Orepic

A growing number of studies have focused on identifying cognitive processes that are modulated by interoceptive signals, particularly in relation to the respiratory or cardiac cycle. Considering the fundamental role of interoception in bodily self-consciou ...

Sensorimotor Induction of Auditory Misattribution in Psychosis is Linked to Neural Disconnectivity

Olaf Blanke, Alessandra Griffa, Patric Hagmann, Andrea Serino, Roy Salomon, Giulio Rognini, Silvia Marchesotti

Background: Schneiderian first rank symptoms (FRS) are characterized by a diminished demarcation of self-other boundaries, causing misattribution of self-generated thoughts and actions to external sources. We have shown that introducing sensorimotor predic ...

Sensorimotor conflicts induce somatic passivity and louden quiet voices in healthy listeners

Olaf Blanke, Giulio Rognini, Nathan Quentin Faivre, Oliver Alan Kannape, Pavo Orepic

Sensorimotor conflicts are known to alter the perception of accompanying sensory signals, and deficits in sensory attenuation have been observed in schizophrenia. In the auditory domain, self-generated tones or voices (compared to tones or voices presented ...

Fronto-Temporal Disconnection Within the Presence Hallucination Network in Psychotic Patients With Passivity Experiences

Olaf Blanke, Patric Hagmann, Alessandra Griffa, Giulio Rognini, Roy Salomon, Nathan Quentin Faivre, Jevita Potheegadoo, Eva Blondiaux, Giedre Stripeikyte

Psychosis, characterized by hallucinations and delusions, is a common feature of psychiatric disease, especially schizophrenia. One prominent theory posits that psychosis is driven by abnormal sensorimotor predictions leading to the misattribution of self- ...

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

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

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 ...

Increased functional connectivity of the intraparietal sulcus underlies the attenuation of numerosity estimations for self-generated words

Olaf Blanke, Giulio Rognini, Nathan Quentin Faivre, Jevita Potheegadoo, Michael Eric Anthony Pereira, Giedre Stripeikyte

Previous studies have shown that self-generated stimuli in auditory, visual, and somatosensory domains are attenuated, producing decreased behavioral and neural responses compared to the same stimuli that are externally generated. Yet, whether such attenua ...

Breathing affect self-other voice discrimination in a bodily state with increased otherness

Olaf Blanke, Nathan Quentin Faivre, Giulio Rognini, Hyeongdong Park, Pavo Orepic

A growing number of studies have focused on identifying cognitive processes that are modulated by interoceptive signals. Here we investigated whether interoception affects self-processing, by assessing changes in self-voice perception as a function of resp ...

Screening of the factors influencing frictional interactions between a cylindrical tip and the cardiac wall using factorial analysis

Bandar Muntazar Hakim, Hannes Bleuler, Giulio Rognini, Lionel Flaction

Knowledge of frictional forces acting on the tips of minimally invasive medical devices is important in the design and simulation of such devices. Moreover, several studies have shown that uncontrolled frictional forces can induce damage to organs. The goa ...

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 ...

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

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

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 ...

A novel manipulation method of human body ownership using an fMRI-compatible master-slave system

Olaf Blanke, Tobias Kober, Wietske Van der Zwaag, Roy Salomon, Giulio Rognini

Bodily self-consciousness has become an important topic in cognitive neuroscience aiming to understand how the brain creates a unified sensation of the self in a body. Specifically, full body illusion (FBI) in which changes in bodily self-consciousness are ...

Robot-induced hallucinations in Parkinson’s disease depend on altered sensorimotor processing in fronto-temporal network

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Nathan Quentin Faivre, Giulio Rognini, Fosco Bernasconi, Michela Bassolino, Jevita Potheegadoo, Michel Akselrod, Eva Blondiaux, Giedre Stripeikyte, Matteo Franza

Hallucinations in Parkinson’s disease (PD) are disturbing and frequent non-motor symptoms and constitute a major risk factor for psychosis and dementia. We report a robotics-based approach applying conflicting sensorimotor stimulation, enabling the inducti ...

Torso-mounted Vibrotactile Interface to Experimentally Induce Illusory Own-body Perceptions

Olaf Blanke, Hannes Bleuler, Giulio Rognini

Recent developments in virtual reality and robotic technologies have allowed investigating the behavioural and brain mechanisms that grounds self-consciousness in the multisensory (e.g. vision and touch) and sensorimotor processing of bodily signals. Yet, ...

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 ...

Modulation of vection latencies in the full-body illusion

Alessandro Nesti, Olaf Blanke, Bruno Herbelin, Giulio Rognini

Current neuroscientific models of bodily self-consciousness (BSC) argue that inaccurate integration of sensory signals leads to altered states of BSC. Indeed, using virtual reality technology, observers viewing a fake or virtual body while being exposed to ...
