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 ...

Bodily self-consciousness as a framework to link sensory information and self-related components of episodic memory: behavioral, neuroimaging, and clinical evidence

Nathalie Heidi Meyer

The recollection of sensory information and subjective experience related to a personal past event depends on our episodic memory (EM). At the neural level, EM retrieval is linked with the reinstatement of hippocampal activity thought to recollect the sens ...

Targeted regeneration of spinal cord neurons across a complete injury restores walking

Marco Milano

Spinal cord injury (SCI) interrupts axonal connections between the brain and the spinal cord, and is characterized by a spectrum of sensorimotor and autonomic impairments. While spontaneous recovery is limited, recent studies have shown that functional imp ...

A new empirical challenge for local theories of consciousness

Adrien Christophe Doerig

Local theories of consciousness state that one is conscious of a feature if it is adequately represented and processed in sensory brain areas, given some background conditions. We challenge the core prediction of local theories based on long-lasting postdi ...

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 ...

Modulation of Bodily Self-Consciousness by Self and External Touch

Olaf Blanke, Roy Salomon, Masayuki Hara, Noriaki Kanayama

The full body illusion (FBI) is a bodily illusion based on the application of multisensory conflicts inducing changes in bodily self-consciousness (BSC), which has been used to study cognitive brain mechanisms underlying body ownership and related aspects ...

Wearable Haptics for Somatosensory Perception and Self-consciousness

Atena Fadaeijouybari

Recent research has highlighted the crucial role of the processing of somatosensory signals involving the torso for global aspects of Bodily Self Consciousness (BSC), i.e., the experience of the conscious "I" as embodied and localized within bodily space. ...

Interoception and Empathy Impact Perspective Taking

Olaf Blanke, Bruno Herbelin, Jane Aspell, Lukas Heydrich

Adopting the perspective of another person is an important aspect of social cognition and has been shown to depend on multisensory signals from one's own body. Recent work suggests that interoceptive signals not only contribute to own-body perception and s ...

Resting-State Brain Activity for Early Prediction Outcome in Postanoxic Patients in a Coma with Indeterminate Clinical Prognosis

Dimitri Nestor Alice Van De Ville

The authors used resting-state fMRI in a prospective study to compare whole-brain functional connectivity between patients with good and poor outcomes, implementing support vector machine learning. They automatically predicted coma outcome using resting-st ...

Response to commentaries on 'hard criteria for empirical theories of consciousness'

Michael Herzog, Adrien Christophe Doerig, Aaron Schurger

In consciousness research, we have a very large number of theories, which exceeds by far the number of theories in other fields. We recently presented a set of criteria for evaluating and comparing theories of consciousness, and then applied the criteria t ...

Breathing is coupled with voluntary action and the cortical readiness potential

Olaf Blanke, Oliver Alan Kannape, Hyeongdong Park, Coline Barnoud, Henri Dan Trang

Voluntary action is a fundamental element of self-consciousness. The readiness potential (RP), a slow drift of neural activity preceding self-initiated movement, has been suggested to reflect neural processes underlying the preparation of voluntary action; ...

First-person body view modulates the neural substrates of episodic memory and autonoetic consciousness: A functional connectivity study

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Bruno Herbelin, Thomas William Arthur Bolton, Nathan Quentin Faivre, Baptiste Gauthier, Robin Mange, Florian Lance, Lucie Bréchet

Episodic memory (EM) is classically conceived as a memory for events, localized in space and time, and characterized by autonoetic consciousness (ANC) allowing to mentally travel back in time and subjectively relive an event. Building on recent evidence th ...

Brainstem Correlates of a Cold Pressor Test Measured by Ultra-High Field fMRI

Dimitri Nestor Alice Van De Ville, Olivier Benoit Thomas Reynaud, Domenica Bueti, Fatma Megdiche

Introduction Modern imaging techniques such as blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) allow the non-invasive and indirect measurement of brain activity. Whether changes in signal intensity can be detected in small ...

Partial-volume modeling reveals reduced gray matter in specific thalamic nuclei early in the time course of psychosis and chronic schizophrenia

Meritxell Bach Cuadra, Patric Hagmann, Kim Do, Erick Jorge Canales Rodriguez, Mario Joao Fartaria de Oliveira, Elena Najdenovska, Zita Rovó

The structural complexity of the thalamus, due to its mixed composition of gray and white matter, make it challenging to disjoint and quantify each tissue contribution to the thalamic anatomy. This work promotes the use of partial-volume-based over probabi ...

The Murten Panorama, from 2D to 4D

Sarah Irene Brutton Kenderdine, Daniel Norbert Jaquet

The Murten Panorama (10x100m) was realised by the renowned German panorama painter Louis Braun (1836-1916) in 1893, commissioned by a Swiss consortium. It commemorates the Swiss victory against the army of the Duchy of Burgundy in 1476 and exists as a symb ...

Coupling Inner and Outer Body for Self-Consciousness

Olaf Blanke, Hyeongdong Park

Although recent studies on self-consciousness emphasized the importance of bodily processing and multisensory integration, such research has focused solely on bodily signals originating from the outside of the body (i.e., exteroceptive bodily signals) or i ...

Heartbeat-evoked cortical responses: Underlying mechanisms, functional roles, and methodological considerations

Olaf Blanke, Hyeongdong Park

The heart continuously and cyclically communicates with the brain. Beyond homeostatic regulation and sensing, recent neuroscience research has started to shed light on brain-heart interactions in diverse cognitive and emotional processes. In particular, ne ...

Underlying mechanisms of episodic autobiographical memory and self-consciousness

Lucie Bréchet

Cognitive neuroscience has been examining consciousness associated with the subject, that is the self of the conscious experience and its related multisensory processing of bodily signals, the so-called bodily self-consciousness. Different line of research ...

Discovery and validation of temporal patterns involved in human brain ketometabolism in cerebral microdialysis fluids of traumatic brain injury patients

Sarah Catherine Sonnay, Anirikh Chakrabarti, Nicolas Christinat, Mojgan Masoodi

Background: Traumatic brain injury (TBI) is recognized as a metabolic disease, characterized by acute cerebral glucose hypo-metabolism. Adaptive metabolic responses to TBI involve the utilization of alternative energy substrates, such as ketone bodies. Cer ...
