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

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

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 ...

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 ...

Prefrontal engrams of long-term fear memory perpetuate pain perception

Johannes Gräff, Yechao Han

A painful episode can lead to a life-long increase in an individual's experience of pain. Fearful anticipation of imminent pain could play a role in this phenomenon, but the neurobiological underpinnings are unclear because fear can both suppress and enhan ...

Interpretable Representation Learning and Evaluation for Abstractive Summarization

Andreas Thomas Marfurt

Abstractive summarization has seen big improvements in recent years, mostly due to advances in neural language modeling, language model pretraining, and scaling models and datasets. While large language models generate summaries that are fluent, coherent, ...

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 ...

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

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

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, Masayuki Hara, 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 ...

Modulation of Bodily Self-Consciousness by Self and External Touch

Olaf Blanke, Roy Salomon, Masayuki Hara, Noriaki Kanayama

The full body illusion (FBI) is a bodily illusion based on the application of multisensory conflicts inducing changes in bodily self-consciousness (BSC), which has been used to study cognitive brain mechanisms underlying body ownership and related aspects ...

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 ...

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

Olaf Blanke, Fosco Bernasconi, Hyeongdong Park, Marco Solcà

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 ...
