Functional MRI Neurofeedback Outperforms Cognitive Behavioral Therapy for Reducing Tinnitus Distress: A Prospective Randomized Clinical Trial

Dimitri Nestor Alice Van De Ville, Nicolas Gninenko

Background: Cognitive behavioral therapy (CBT) is the current standard treatment for chronic severe tinnitus; however, preliminary evidence suggests that real-time functional MRI (fMRI) neurofeedback therapy may be more effective. Purpose: To compare the e ...

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 ...

Triple Network Model Dynamically Revisited: Lower Salience Network State Switching in Pre-psychosis

Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton

Emerging evidence has attributed altered network coordination between the default mode, central executive, and salience networks (DMN/CEN/SAL) to disturbances seen in schizophrenia, but little is known for at-risk psychosis stages. Moreover, pinpointing im ...

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, Polona Pozeg, Pierre Progin

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 ...

Depersonalization- and derealization-like phenomena of epileptic origin

Olaf Blanke, Lukas Heydrich, Nathaniel Evans

Objective Depersonalization refers to the sensation of being detached from one's body, often associated with feelings of loss of control over one's own body, actions, or thoughts. Derealization refers to the altered perception of one's surroundings that is ...

Magic Prints: Image-Changing Prints Observed under Visible and 365 nm UV Light

Petar Pjanic, Marjan Shahpaski

In this paper we propose a novel layered-printing method consisting of superposed visible cmy and invisible fluorescent ultraviolet (UV) rgb inks. Our approach can be used to generate a variety of visual color-alteration effects such as revealing two compl ...

Resting-State Networks of Adolescents Experiencing Depersonalization-Like Illusions: Cross-sectional and Longitudinal Findings

Dimitri Nestor Alice Van De Ville, François Lazeyras

The mirror-gazing task (MGT) experimentally induces illusions, ranging from simple color changes in the specular image of oneself, to depersonalization-like anomalous self-experiences (ASE) as in experiencing one's specular image as someone else. The objec ...

Modulation of vection latencies in the full-body illusion

Olaf Blanke, Bruno Herbelin, Alessandro Nesti, Giulio Rognini

Current neuroscientific models of bodily self-consciousness (BSC) argue that inaccurate integration of sensory signals leads to altered states of BSC. Indeed, using virtual reality technology, observers viewing a fake or virtual body while being exposed to ...

Bodily ownership and self-location: Components of bodily self-consciousness

Andrea Serino, Christophe Lopez

Recent research on bodily self-consciousness has assumed that it consists of three distinct components: the experience of owning a body (body ownership); the experience of being a body with a given location within the environment (self-location); and the e ...

Duration and not strength of activation in temporo-parietal cortex positively correlates with schizotypy

Olaf Blanke, Christine Mohr

Impaired self- and own body processing in patients with schizophrenia and individuals along the schizophrenia spectrum have been associated with dysfunctional cortical activation at the temporo-parietal junction. Here we investigated whether strength or du ...

Dysconnection Topography in Schizophrenia Revealed with State-Space Analysis of EEG

Martin Hasler, Oscar De Feo, Kim Do, Reto Meuli, Mahdi Jalili

Background The dysconnection hypothesis has been proposed to account for pathophysiological mechanisms underlying schizophrenia. Widespread structural changes suggesting abnormal connectivity in schizophrenia have been imaged. A functional counterpart of t ...

Perceptual aberrations impair mental own-body transformations

Olaf Blanke, Christine Mohr, Peter Andreas Brugger

Dysfunctional self and bodily processing have been reported from the schizophrenia spectrum. Here, the authors tested 72 students (40 women) to determine whether performance in a mental own-body transformation task relates to self-rated frequency of sponta ...
