Plasticity of sensory representations in the posterior insular cortex during fear learning

Denys Osypenko

Aversively-motivated associative learning allows animals to avoid harm and thus ensures survival. Aversive learning can be studied by the fear learning paradigm, in which an innocuous sensory stimulus like a tone (conditioned stimulus, CS), acquires a nega ...

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 ...

An insular cortex - lateral amygdala network in fear learning

Shriya Palchaudhuri

Animals are capable of evaluating sensory cues for possible threats and adapting their behaviours accordingly. Fear learning is an evolutionarily conserved behaviour crucial for animal survival, during which sensory percepts with a negative reinforcing qua ...

The perspectives of mapping and monitoring of the sense of self in neurosurgical patients

Olaf Blanke, Bruno Herbelin, Sophie Jacqueline Andrée Betka, Hyeongdong Park, Pavo Orepic, Sixto Luis Alcoba Banqueri

Surgical treatment of tumors, epileptic foci or of vascular origin, requires a detailed individual pre-surgical workup and intra-operative surveillance of brain functions to minimize the risk of post-surgical neurological deficits and decline of quality of ...

Target cell-type specificity of a cortico-amygdala long range synaptic connection

Ayah Khubieh

An important function of the brain is to analyze sensory information, and to modulate animal behaviour according to previous experience. During processes of emotional learning, sensory percepts with a reinforcing quality, also called unconditioned stimuli ...

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, 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 ...

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 ...

Human thermal perception and time of day: A review

Giorgia Chinazzo, Jeffrey Turner Hubbard

The circadian clock regulates diurnal variations in autonomic thermoregulatory processes such as core body temperature in humans. Thus, we might expect that similar daily fluctuations also characterize human thermal perception, the ultimate role of which i ...

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 ...

Breathing affect self-other voice discrimination in a bodily state with increased otherness

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

A growing number of studies have focused on identifying cognitive processes that are modulated by interoceptive signals. Here we investigated whether interoception affects self-processing, by assessing changes in self-voice perception as a function of resp ...

Imagined paralysis alters somatosensory evoked-potentials

Olaf Blanke, Estelle Palluel, Silvia Marchesotti

Recent studies employing body illusions have shown that multisensory conflict can alter body representations and modulate low-level sensory processing. One defining feature of these body illusions is that they are sensory driven and thus passive on behalf ...

TMS-induced control of bodily self-consciousness by combining non-invasive brain stimulation and immersive virtual reality

Matteo Franza

Our brain constantly receives and integrates a flow of sensory and motor information that shapes the way our body is represented. Several experimental approaches have been proposed to alter the body representation, by manipulating exteroceptive or interoce ...

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 ...

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 ...

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 ...

Sad faces increase the heartbeat-associated interoceptive information flow within the salience network: a MEG study

Hyeongdong Park, Young Min Kim

The somatic marker hypothesis proposes that the cortical representation of visceral signals is a crucial component of emotional processing. No previous study has investigated the information flow among brain regions that process visceral information during ...

Cognitive neuroprosthetics for investigating and restoring body perception

Marco Solcà

Our brain constantly receives and integrates a flow of multisensory bodily inputs that are responsible for the way our body is represented and consciously experienced. However, in some pathological conditions, patients might experience altered perceptions ...

Hand perceptions induced by single pulse transcranial magnetic stimulation over the primary motor cortex

Olaf Blanke, Andrea Serino, Michela Bassolino, Matteo Franza

Background When single pulse transcranial magnetic stimulation (TMS) is applied over the primary motor cortex (M1) with sufficient intensity, it evokes muscular contractions (motor-evoked potentials, MEPs) and muscle twitches (TMS-evoked movements). Partic ...

Creating a neuroprosthesis for active tactile exploration of textures

Solaiman Shokur, Miguel Nicolelis

Intracortical microstimulation (ICMS) of the primary somatosensory cortex (S1) can produce percepts that mimic somatic sensation and, thus, has potential as an approach to sensorize prosthetic limbs. However, it is not known whether ICMS could recreate act ...
