Real-time fMRI neurofeedback modulates induced hallucinations and underlying brain mechanisms

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Jevita Potheegadoo, Herberto Dhanis Pedro De Barros Camacho, Elenor Morgenroth, Nicolas Gninenko, Nathan Quentin Faivre, Giulio Rognini

Hallucinations can occur in the healthy population, are clinically relevant and frequent symptoms in many neuropsychiatric conditions, and have been shown to mark disease progression in patients with neurodegenerative disorders where antipsychotic treatmen ...

Neuroengineering of hallucinations through fMRI neurofeedback: Understanding and modulating neural dynamics for the control of hallucinations in health and disease

Herberto Dhanis Pedro De Barros Camacho

Recent years have seen considerable progress in understanding brain function, and in modulating it through real-time fMRI neurofeedback (NF). Inspired by these advances, paired with the unique possibility of inducing the clinically relevant Presence Halluc ...

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

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

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 ...

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

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

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 ...

TbCAPs: A toolbox for co-activation pattern analysis

Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Constantin Tuleasca, Herberto Dhanis Pedro De Barros Camacho, Elenor Morgenroth, Farnaz Delavari, Eva Blondiaux, Baptiste Gauthier, Gwladys Rey, Lukasz Dawid Smigielski

Functional magnetic resonance imaging provides rich spatio-temporal data of human brain activity during task and rest. Many recent efforts have focussed on characterising dynamics of brain activity. One notable instance is co-activation pattern (CAP) analy ...

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

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

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 ...

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

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

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 ...
