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 ...

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 ...

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 ...

Embodiment in episodic memory through premotor-hippocampal coupling

Olaf Blanke, Bruno Herbelin, Jevita Potheegadoo, Mariana Babo Rebelo, Nathalie Heidi Meyer, Baptiste Gauthier, Florian Lance

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 ...

Numerosity estimation impairment measurement system

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

Numerosity estimation impairment measurement system for diagnostic/prognosis of a neurologi- cal disorder comprising an electronic display device configured to present 3D scene representa- tions/images comprising a plurality of 3D virtual visual stimulus t ...

Sense of agency during encoding predicts subjective reliving

Olaf Blanke, Jevita Potheegadoo, Nathalie Heidi Meyer, Baptiste Gauthier, Florian Lance

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 ...

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 ...

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

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, 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 ...
