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 ...

The electrophysiological effects of the serotonin 1A receptor agonist buspirone in emotional face processing

Fosco Bernasconi

Emotional face processing is critically modulated by the serotonergic system, and serotonin (5-HT) receptor agonists impair emotional face processing. However, the specific contribution of the 5-HT1A receptor remains poorly understood. Here we investigated ...

Behavioral and neurophysiological evidence for altered interoceptive bodily processing in chronic pain

Olaf Blanke, Fosco Bernasconi, Marco Solcà, Hyeongdong Park

Whereas impaired multisensory processing of bodily stimuli and distorted body representation are well-established in various chronic pain disorders, such research has focused on exteroceptive bodily cues and neglected bodily signals from the inside of the ...

Visual hallucinations in Parkinson's disease are associated with deficits in social perception

Olaf Blanke, Fosco Bernasconi, Jevita Potheegadoo, Louis Philippe Albert, Neza Vehar

Most structured visual hallucinations (VH) in Parkinson's disease (PD) involve animate-social objects, yet current theories fail to account for the prominent social component of VH in PD. To study social perception in PD patients with VH in a behavioral ta ...

Robotically-induced auditory-verbal hallucinations: combining self-monitoring and strong perceptual priors

Olaf Blanke, Fosco Bernasconi, Nathan Quentin Faivre, Pavo Orepic, Melissa Faggella

Background. Inducing hallucinations under controlled experimental conditions in nonhallucinating individuals represents a novel research avenue oriented toward understanding complex hallucinatory phenomena, avoiding confounds observed in patients. Audito ...

Subcortical correlates of consciousness with human single neuron recordings

Olaf Blanke, Fosco Bernasconi, Nathan Quentin Faivre, Michael Eric Anthony Pereira

Subcortical brain structures such as the basal ganglia or the thalamus are involved in regulating motor and cognitive behavior. However, their contribution to perceptual consciousness is still unclear, due to the inherent difficulties of recording subcorti ...

Self-grounded vision: hand ownership modulates visual location through cortical beta and gamma oscillations

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon, Fosco Bernasconi, Javier Bello Ruiz, Herberto Dhanis Pedro De Barros Camacho

Vision is known to be shaped by context, defined by environmental and bodily signals. In the Taylor illusion, the size of an afterimage projected on one's hand changes according to proprioceptive signals conveying hand position. Here, we assessed whether t ...

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

Olaf Blanke, Bruno Herbelin, Andrea Serino, Fosco Bernasconi, Javier Bello Ruiz, Elisa Canzoneri, Robin Mange

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 ...

Transient Modulations of Neural Responses to Heartbeats Covary with Bodily Self-Consciousness

Olaf Blanke, Roy Salomon, Fosco Bernasconi, Hyeongdong Park, Javier Bello Ruiz, Christian Pfeiffer

Recent research has investigated self-consciousness associated with the multisensory processing of bodily signals (e.g., somatosensory, visual, vestibular signals), a notion referred to as bodily self-consciousness, and these studies have shown that the ma ...

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 ...

Home-based online line bisection test detects visuo-spatial neglect and pseudoneglect in Parkinson's disease

Olaf Blanke, Fosco Bernasconi, Jevita Potheegadoo, Louis Philippe Albert

Introduction: Parkinson's Disease (PD) may lead to cognitive symptoms, including visuo-spatial attentional deficits such as unilateral spatial neglect (USN). Although there is some evidence for USN in PD patients, especially in those with left-sided onset ...

Theta oscillations and minor hallucinations in Parkinson’s disease reveal decrease in frontal lobe functions and later cognitive decline

Olaf Blanke, Fosco Bernasconi

Cognitive decline and hallucinations are common and debilitating non-motor symptoms, usually occurring during later phases of Parkinson’s disease (PD). Minor hallucinations (MH) appear early in the disease course and have been suggested to predict cognitiv ...

Audio-Tactile and Peripersonal Space Processing Around the Trunk in Human Parietal and Temporal Cortex: An Intracranial EEG Study

Olaf Blanke, Andrea Serino, Fosco Bernasconi, Nathan Quentin Faivre, Hyeongdong Park

Interactions with the environment happen within one's peripersonal space (PPS)-the space surrounding the body. Studies in monkeys and humans have highlighted a multisensory distributed cortical network representing the PPS. However, knowledge about the tem ...

Phantom Boarder Relates to Experimentally‐Induced Presence Hallucinations in Parkinson's Disease

Olaf Blanke, Fosco Bernasconi, Jevita Potheegadoo

Phantom boarder (PB) is the sensation that someone uninvited is in the patient's home despite evidence to the contrary. It is mostly reported by patients with neurodegenerative disorders such as Alzheimer's disease, dementia with Lewy bodies or Parkinson's ...

Distinct vestibular effects on early and late somatosensory cortical processing in humans

Olaf Blanke, Fosco Bernasconi, Michiel van Elk, Christian Pfeiffer

In non-human primates several brain areas contain neurons that respond to both vestibular and somatosensory stimulation. In humans, vestibular stimulation activates several somatosensory brain regions and improves tactile perception. However, less is known ...
