An invisible touch: Body-related multisensory conflicts modulate visual consciousness

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon, Javier Bello Ruiz

The majority of scientific studies on consciousness have focused on vision, exploring the cognitive and neural mechanisms of conscious access to visual stimuli. In parallel, studies on bodily consciousness have revealed that bodily (i.e. tactile, proprioce ...

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 ...

Entrainment of Voluntary Movement to Undetected Auditory Regularities

Olaf Blanke, Nathan Quentin Faivre, Leila Cammoun, Aaron Schurger

In physics “entrainment” refers to the synchronization of two coupled oscillators with similar fundamental frequencies. In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked ...

Multisensory perceptual awareness: Categorical or graded?

Olaf Blanke, Nathan Quentin Faivre

Neural evidence suggests that mechanisms associated with conscious access (i.e., the ability to report on a conscious state) are “all-or-none”. Upon crossing some threshold, neural signals are globally broadcast throughout the brain and allow conscious rep ...

Audio-Tactile and Peripersonal Space Processing Around the Trunk in Human Parietal and Temporal Cortex: An Intracranial EEG Study

Olaf Blanke, Andrea Serino, Fosco Bernasconi, Nathan Quentin Faivre, Hyeongdong Park

Interactions with the environment happen within one's peripersonal space (PPS)-the space surrounding the body. Studies in monkeys and humans have highlighted a multisensory distributed cortical network representing the PPS. However, knowledge about the tem ...

Numerical Priming Between Touch and Vision Depends on Tactile Discrimination

Laurène Véronique Vuillaume, Olaf Blanke, Nathan Quentin Faivre, Roy Salomon

Although the interaction between vision and touch is of crucial importance for perceptual and bodily self-consciousness, only little is known regarding the link between conscious access and tactile processing. Here, we tested whether the numerical encoding ...

A direct comparison of unconscious face processing under masking and interocular suppression

Nathan Quentin Faivre

Different combinations of forward and backward masking as well as interocular suppression have been used extensively to render stimuli invisible and to study those aspects of visual stimuli that are processed in the absence of conscious experience. Althoug ...

Consciousness is more than meets the eye: a call for a multisensory study of subjective experience

Nathan Quentin Faivre, Roy Salomon

Over the last 30 years, our understanding of the neurocognitive bases of consciousness has improved, mostly through studies employing vision. While studying consciousness in the visual modality presents clear advantages, we believe that a comprehensive sci ...

Sense of self impacts spatial navigation and hexadirectional coding in human entorhinal cortex

Olaf Blanke, Nathan Quentin Faivre, Hyeongdong Park, Baptiste Gauthier, Hyukjun Moon

Grid cells in entorhinal cortex (EC) encode an individual’s location in space and rely on environmental cues and self-motion cues derived from the individual’s body. Body-derived signals are also primary signals for the sense of self and based on integrate ...

The Confidence Database

Nathan Quentin Faivre, Inaki Asier Iturrate Gil, Michael Eric Anthony Pereira

Understanding how people rate their confidence is critical for the characterization of a wide range of perceptual, memory, motor and cognitive processes. To enable the continued exploration of these processes, we created a large database of confidence stud ...

Sustained invisibility through crowding and continuous flash suppression: a comparative review

Nathan Quentin Faivre

The study of non-conscious vision benefits from several alternative methods that allow the suppression of an image from awareness. Here, we present and compare two of them that are particularly well-suited for creating sustained periods of invisibility, na ...

Evidence accumulation relates to perceptual consciousness and monitoring

Wenwen Chang, Olaf Blanke, Fosco Bernasconi, Nathan Quentin Faivre, Michael Eric Anthony Pereira

A fundamental scientific question concerns the neural basis of perceptual consciousness and perceptual monitoring resulting from the processing of sensory events. Although recent studies identified neurons reflecting stimulus visibility, their functional r ...

Functional Disconnection Within The Presence Hallucination Network In Psychotic Patients With First-Rank Symptoms

Olaf Blanke, Patric Hagmann, Giulio Rognini, Nathan Quentin Faivre, Jevita Potheegadoo, Giedre Stripeikyte

OXFORD UNIV PRESS2019

Bone conduction facilitates self-other voice discrimination

Olaf Blanke, Nathan Quentin Faivre, Oliver Alan Kannape, Pavo Orepic

One's own voice is one of the most important and most frequently heard voices. Although it is the sound we associate most with ourselves, it is perceived as strange when played back in a recording. One of the main reasons is the lack of bone conduction tha ...

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 ...

Sensorimotor conflicts alter metacognitive and action monitoring

Olaf Blanke, Roy Salomon, Fosco Bernasconi, Nathan Quentin Faivre, Laurène Véronique Vuillaume

While sensorimotor signals are known to modulate perception, little is known about their influence on higher-level cognitive processes. Here, we applied sensorimotor conflicts while participants performed a perceptual task followed by confidence judgments. ...

Neural Mechanisms Of Robot-Induced Hallucinations In Healthy Participants And Symptomatic Hallucinations Of Neurological And Psychiatric Origin

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Patric Hagmann, Giulio Rognini, Nathan Quentin Faivre, Jevita Potheegadoo, Eva Blondiaux, Giedre Stripeikyte, Michel Akselrod

Disentangling the origins of confidence in speeded perceptual judgments through multimodal imaging

Arnaud Marc Desvachez, Dimitri Nestor Alice Van De Ville, Olaf Blanke, José del Rocio Millán Ruiz, Inaki Asier Iturrate Gil, Nathan Quentin Faivre, Michael Eric Anthony Pereira, Stéphanie Martin

The human capacity to compute the likelihood that a decision is correct—known as metacognition—has proven difficult to study in isolation as it usually cooccurs with decision making. Here, we isolated postdecisional from decisional contributions to metacog ...
