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 ...

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

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

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- ...

Sense of agency during encoding predicts subjective reliving

Olaf Blanke, Jevita Potheegadoo, Baptiste Gauthier, Nathalie Heidi Meyer, Florian Lance, Juliette Marie Elise Jocelyne Boscheron

Autonoetic consciousness (ANC), the ability to re-experience personal past events links episodic memory and self-consciousness by bridging awareness of oneself in a past event (i.e., during its encoding) with awareness of oneself in the present (i.e., duri ...

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

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

Embodiment in episodic memory through premotor-hippocampal coupling

Olaf Blanke, Bruno Herbelin, Jevita Potheegadoo, Baptiste Gauthier, Nathalie Heidi Meyer, Florian Lance, Mariana Babo Rebelo, Sara Stampacchia, Juliette Marie Elise Jocelyne Boscheron

Episodic memory (EM) allows us to remember and relive past events and experiences and has been linked to cortical-hippocampal reinstatement of encoding activity. While EM is fundamental to establish a sense of self across time, this claim and its link to t ...

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 ...

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 ...

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

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

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 ...

The diagnostic performance of functional dopaminergic scintigraphic imaging in the diagnosis of dementia with Lewy bodies: an updated systematic review

Olaf Blanke, Fosco Bernasconi, Jevita Potheegadoo, Sara Stampacchia

IntroductionDopaminergic scintigraphic imaging is a cornerstone to support the diagnosis in dementia with Lewy bodies. To clarify the current state of knowledge on this imaging modality and its impact on clinical diagnosis, we performed an updated systemat ...

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 ...

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

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

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 ...
