Restoration of natural thermal sensation in upper-limb amputees

Solaiman Shokur, Simon Gallo, Giulio Rognini, Silvestro Micera, Jonathan Louis Muheim, Outman Akouissi

The use of hands for gathering rich sensory information is essential for proper interaction with the environment; therefore, the restoration of sensation is critical for reestablishing the sense of embodiment in hand amputees. Here, we show that a noninvas ...

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

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

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 ...

Neuroscience robotics for controlled induction and real-time assessment of hallucinations

Olaf Blanke, Laurent Frédéric Jenni, Masayuki Hara, Giulio Rognini, Eva Blondiaux, Fosco Bernasconi, Herberto Dhanis Pedro De Barros Camacho, Jevita Potheegadoo

Although hallucinations are important and frequent symptoms in major psychiatric and neurological diseases, little is known about their brain mechanisms. Hallucinations are unpredictable and private experiences, making their investigation, quantification a ...

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 ...

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

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Thomas William Arthur Bolton, Giulio Rognini, Eva Blondiaux, Nathan Quentin Faivre, 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 ...

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

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

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 ...

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

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

Enhancing analgesic spinal cord stimulation for chronic pain with personalized immersive virtual reality

Robin Mange, Bruno Herbelin, Olaf Blanke, Giulio Rognini, Andrea Serino, Marco Solcà, Pavo Orepic

Spinal cord stimulation (SCS) is an approved treatment for truncal and limb neuropathic pain. However, pain relief is often suboptimal and SCS efficacy may reduce over time, requiring sometimes the addition of other pain therapies, stimulator revision, or ...

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

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

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- ...

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

Olaf Blanke, Oliver Alan Kannape, Giulio Rognini, Nathan Quentin Faivre, 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 ...

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

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. Here we investigated whether interoception affects self-processing, by assessing changes in self-voice perception as a function of resp ...

Sensorimotor Induction of Auditory Misattribution in Early Psychosis

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Silvia Marchesotti, Roy Salomon, Andrea Serino, Fosco Bernasconi, Kim Do

Dysfunction of sensorimotor predictive processing is thought to underlie abnormalities in self-monitoring producing passivity symptoms in psychosis. Experimentally induced sensorimotor conflict can produce a failure in bodily self-monitoring (presence hall ...
