Neural Basis of Internal Attention in Adults with Pure and Comorbid ADHD

Farnaz Delavari

Objective: To examine whether putatively atypical neuronal activity during internal attention in ADHD yields insights into processes underlying emotion dysregulation. Methods: We used a word processing paradigm to assess neural activations in adults with A ...

Antibody-Coated Wearable Organic Electrochemical Transistors for Cortisol Detection in Human Sweat

Danick Briand, Silvia Demuru, Jaemin Kim

The dysregulation of the hormone cortisol is related to several pathological states, and its monitoring could help prevent severe stress, fatigue, and mental diseases. While wearable antibody-based biosensors could allow real-time and simple monitoring of ...

Breathing affects self-other voice discrimination in a bodily state associated with somatic passivity

Olaf Blanke, Giulio Rognini, Nathan Quentin Faivre, Hyeongdong Park, Pavo Orepic

A growing number of studies have focused on identifying cognitive processes that are modulated by interoceptive signals, particularly in relation to the respiratory or cardiac cycle. Considering the fundamental role of interoception in bodily self-consciou ...

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 ...

Behavioral and neurophysiological evidence for altered interoceptive bodily processing in chronic pain

Olaf Blanke, Fosco Bernasconi, Marco Solcà, Hyeongdong Park

Whereas impaired multisensory processing of bodily stimuli and distorted body representation are well-established in various chronic pain disorders, such research has focused on exteroceptive bodily cues and neglected bodily signals from the inside of 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 ...

RETRACTED: Insular cortex processes aversive somatosensory information and is crucial for threat learning

Ralf Schneggenburger, Olexiy Kochubey, Wei Tang, Denys Osypenko, Michael Kintscher, Shriya Palchaudhuri, Emmanuelle Marie Brigitte Berret

Learning about threats is essential for survival. During threat learning, an innocuous sensory percept such as a tone acquires an emotional meaning when paired with an aversive stimulus such as a mild footshock. The amygdala is critical for threat memory f ...

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 ...

Bodily self-consciousness and its disorders, The Parietal Lobe

Olaf Blanke, Hyeongdong Park, Roberta Ronchi

Research in clinical and human neuroscience indicates that important brain mechanisms of self-consciousness are based on the integration of multisensory bodily signals (i.e., bodily self-consciousness: BSC), including signals coming from outside our body ( ...

Interferences between breathing, experimental dyspnoea and bodily self-consciousness

Olaf Blanke, Bruno Herbelin, Javier Bello Ruiz, Elisa Canzoneri

Dyspnoea, a subjective experience of breathing discomfort, is a most distressing symptom. It implicates complex cortical networks that partially overlap with those underlying bodily self-consciousness, the experience that the body is one's own within a giv ...

Bilateral Rolandic operculum processing underlying heartbeat awareness reflects changes in bodily self-consciousness

Olaf Blanke, Andrea Serino, Bruno Herbelin, Roy Salomon, Roberto Martuzzi, Javier Bello Ruiz, Maria Laura Blefari

Exteroceptive bodily signals (including tactile, proprioceptive and visual signals) are important information contributing to self-consciousness. Moreover, prominent theories proposed that visceral signals about internal bodily states are equally or even m ...

The Insula Mediates Access to Awareness of Visual Stimuli Presented Synchronously to the Heartbeat

Olaf Blanke, Bruno Herbelin, Nathan Quentin Faivre, Roy Salomon, Javier Bello Ruiz, Roberta Ronchi, Jonathan Dönz

The processing of interoceptive signals in the insular cortex is thought to underlie self-awareness. However, the influence of interoception on visual awareness and the role of the insular cortex in this process remain unclear. Here, we show in a series of ...

Right insular damage decreases heartbeat awareness and alters cardio-visual effects on bodily self-consciousness

Olaf Blanke, Bruno Herbelin, Javier Bello Ruiz, Roberta Ronchi

Recent evidence suggests that multisensory integration of bodily signals involving exteroceptive or interoceptive information modulates bodily aspects of self-consciousness such as self-identification and self-location. In the so-called full body illusion ...

Suppression of the auditory N1-component for heartbeat-related sounds reflects interoceptive predictive coding

Olaf Blanke, Michiel van Elk, Lukas Heydrich

Although many studies have elucidated the neurocognitive mechanisms supporting the processing of externally generated sensory signals, less is known about the processing of interoceptive signals related to the viscera. Drawing a parallel with research on a ...

Turning Body and Self Inside Out. Visualized Heartbeats Alter Bodily Self-Consciousness and Tactile Perception

Olaf Blanke, Bruno Herbelin, Jane Aspell, Lukas Heydrich

Prominent theories highlight the importance of bodily perception for self-consciousness, but it is currently not known whether bodily perception is based on interoceptive or exteroceptive signals or on integrated signals from these anatomically distinct sy ...

Distinct illusory own-body perceptions caused by damage to posterior insula and extrastriate cortex

Olaf Blanke, Lukas Heydrich

Recent research in cognitive neuroscience using virtual reality, robotic technology and brain imaging has linked self-consciousness to the processing and integration of multisensory bodily signals. This work on bodily self-consciousness has implicated the ...

Sleep paralysis in narcolepsy: more than just a motor dissociative phenomenon?

Francesco Manni

Sleep paralyses are viewed as pure motor phenomena featured by a dissociated state in which REM-related muscle atonia coexists with a wakefulness state of full consciousness. We present a 59-year-old man diagnosed with narcolepsy experiencing sleep paralys ...
