Deep-learning models of the ascending proprioceptive pathway are subject to illusions

Olaf Blanke, Alexander Mathis, Merkourios Simos

Proprioception is essential for perception and action. Like any other sense, proprioception is also subject to illusions. In this study, we model classic proprioceptive illusions in which tendon vibrations lead to biases in estimating the state of the body ...

Pre-movement sensorimotor oscillations shape the sense of agency by gating cortical connectivity

Bruno Herbelin, Olaf Blanke, Nathaniel Evans, Bastien Orset

Our sense of agency, the subjective experience of controlling our actions, is a crucial component of self-awareness and motor control. It is thought to originate from the comparison between intentions and actions across broad cortical networks. However, th ...

Human self and Neurosurgery: Advances and insights from Geneva

Bruno Herbelin, Olaf Blanke

Introduction: The preservation of the human self—a fundamental yet underexplored aspect of neurosurgical practice—has gained increasing attention in recent years. Research question: How can neural correlates of self-consciousness be identified, monitored, ...

Focused Ultrasound Neuromodulation: Exploring a Novel Treatment for Severe Opioid Use Disorder

Olaf Blanke, Nathalie Heidi Meyer

BACKGROUND: Opioid use disorder remains a critical health care challenge because current therapeutic strategies have limitations that result in high recurrence and deaths. We evaluated the safety and feasibility of focused ultrasound (FUS) neuromodulation ...

Body and self in functional neurological disorders*

Olaf Blanke

In this commentary, we comment on the closing remarks from Mark Solms at the 2024 International Neuropsychoanalysis conference in light of recent developments in neurosciences around functional neurological disorders (FND). FND is the new term used to desi ...

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 ...

Meditation in the third-person perspective modulates minimal self and heartbeat-evoked potentials

Bruno Herbelin, Olaf Blanke

Experienced meditation practitioners often report altered states of their sense of self, including decentering and distancing the self from the body and one's current concerns. Altered states of the sense of self, such as disembodiment and distancing of th ...

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 ...

Cerebral amyloid angiopathy in patients with Dementia with Lewy Bodies: A clinical and hippocampal morphology study

Olaf Blanke, Alessandra Griffa

Introduction: Dementia with Lewy Bodies (DLB) is often associated with Cerebral Amyloid Angiopathy (CAA) based on pathological studies. Current literature in DLB reveals heterogenous findings regarding CAA effects on cognition, but overall suggests a diffu ...

Neuronal responses in the human primary motor cortex coincide with the subjective onset of movement intention in brain-machine interface-mediated actions

Olaf Blanke, Marco Solcà, Pavo Orepic

Self-initiated behavior is accompanied by the experience of intending our actions. Here, we leverage the unique opportunity to examine the full intentional chain-from intention to action to environmental effects-in a tetraplegic person outfitted with a pri ...

Changes in spatial self-consciousness elicit grid cell–like representation in the entorhinal cortex

Olaf Blanke, Hyeongdong Park, Hyukjun Moon, Baptiste Gauthier, Emanuela De Falco, Louis Philippe Albert, Corentin Marie Hervé Robert Tasu

Grid cells in the entorhinal cortex (EC) encode an individual’s location in space, integrating both environmental and multisensory bodily cues. Notably, body-derived signals are also primary signals for the sense of self. While studies have demonstrated th ...

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

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

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 ...

Customizing the human-avatar mapping based on EEG error related potentials during avatar-based interaction

Ronan Boulic, Ricardo Andres Chavarriaga Lozano, Bruno Herbelin, José del Rocio Millán Ruiz, Olaf Blanke, Fumiaki Iwane, Thibault Serge Mario Porssut

Objective. A key challenge of virtual reality (VR) applications is to maintain a reliable human-avatar mapping. Users may lose the sense of controlling (sense of agency), owning (sense of body ownership), or being located (sense of self-location) inside th ...

Out-of-body experiences in relation to lucid dreaming and sleep paralysis: A theoretical review and conceptual model

Olaf Blanke, Hsin-Ping Wu

Out-of-body experiences (OBEs) are characterized by the subjective experience of being located outside the physical body. Little is known about the neurophysiology of spontaneous OBEs, which are often reported by healthy individuals as occurring during sta ...

Noninvasive modulation of the hippocampal-entorhinal complex during spatial navigation in humans

Olaf Blanke, Elena Beanato, Hyukjun Moon, Esra Neufeld, Friedhelm Christoph Hummel, Maximilian Jonas Wessel, Baptiste Gauthier, Traian Popa, Pierre Theopistos Vassiliadis, Emanuela De Falco, Pauline Menoud, Fabienne Windel

Because of the depth of the hippocampal-entorhinal complex (HC-EC) in the brain, understanding of its role in spatial navigation via neuromodulation was limited in humans. Here, we aimed to better elucidate this relationship in healthy volunteers, using tr ...

Embodiment in episodic memory through premotor-hippocampal coupling

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

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 ...
