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 ...

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 ...

Cogno-Vest: A Torso-Worn, Force Display to Experimentally Induce Specific Hallucinations and Related Bodily Sensations

Olaf Blanke, Hannes Bleuler, Jevita Potheegadoo, Oliver Alan Kannape, Kenny Jeanmonod, Atena Fadaeijouybari

Recent advances in virtual reality and robotic technologies have allowed researchers to explore the mechanisms underlying bodily aspects of self-consciousness which are largely attributed to the multisensory and sensorimotor processing of bodily signals (b ...

Metabolic signature in nucleus accumbens for anti-depressant-like effects of acetyl-L-carnitine

Rolf Gruetter, Maria del Carmen Sandi Perez, Jocelin Grosse, Antoine Timothée Cherix, João Pedro de Matos Rodrigues, Thomas Didier Larrieu

Emerging evidence suggests that hierarchical status provide vulnerability to develop stress-induced depression. Energy metabolic changes in the nucleus accumbens (NAc) were recently related to hierarchical status and vulnerability to develop depression-lik ...

Unraveling neural and behavioral mechanisms of cognitive self-attenuation and alienation

Giedre Stripeikyte

The present thesis aimed at investigating behavioral and neural underpinnings of the mechanisms related to the different aspects of self-monitoring. The first aim was to study functional connectivity alterations related to the mechanisms accounting for the ...

Thought consciousness and source monitoring depend on robotically-controlled sensorimotor conflicts and illusory states

Olaf Blanke, Hannes Bleuler, Andrea Serino, Giulio Rognini, Roy Salomon, Fosco Bernasconi, Marco Solcà, Giedre Stripeikyte, Polona Pozeg, Herberto Dhanis Pedro De Barros Camacho

Thought insertion (TI) is characterized by the experience that certain thoughts, occurring in one’s mind, are not one’s own, but the thoughts of somebody else and suggestive of a psychotic disorder. We report a robotics-based method able to investigate the ...

Hallucination Engineering: From Neuroscience Robotics to Hallucinations in Health and Disease

Eva Blondiaux

My thesis focuses on a psychotic symptom called the presence hallucination (PH). PHs are defined as the false perception that someone is nearby when no one is actually present. PHs can occur in various populations, ranging from healthy subjects (when expos ...
