A striatal circuit balances learned fear in the presence and absence of sensory cues

Ralf Schneggenburger, Olexiy Kochubey, Michael Kintscher

During fear learning, defensive behaviors like freezing need to be finely balanced in the presence or absence of threat-predicting cues (conditioned stimulus, CS). Nevertheless, the circuits underlying such balancing are largely unknown. Here, we investiga ...

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 ...

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 ...

Multi-centre classification of functional neurological disorders based on resting-state functional connectivity

Dimitri Nestor Alice Van De Ville, Jonas Richiardi

Background: Patients suffering from functional neurological disorder (FND) experience disabling neurological symptoms not caused by an underlying classical neurological disease (such as stroke or multiple sclerosis). The diagnosis is made based on reliable ...

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

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

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 ...

An overlapping pattern of cerebral cortical thinning is associated with both positive symptoms and aggression in schizophrenia via the ENIGMA consortium

Erick Jorge Canales Rodriguez, Wenhao Jiang

Background Positive symptoms are a useful predictor of aggression in schizophrenia. Although a similar pattern of abnormal brain structures related to both positive symptoms and aggression has been reported, this observation has not yet been confirmed in a ...

Increased Neural Strength and Reliability to Audiovisual Stimuli at the Boundary of Peripersonal Space

Andrea Serino, Jean-Paul Noel

The actionable space surrounding the body, referred to as peripersonal space (PPS), has been the subject of significant interest of late within the broader framework of embodied cognition. Neurophysiological and neuroimaging studies have shown the represen ...

Common Recruitment of Angular Gyrus in Episodic Autobiographical Memory and Bodily Self-Consciousness

Olaf Blanke, Lucie Bréchet, Baptiste Gauthier, Petr Grivaz

Parietal cortex and adjacent parts of the temporal cortex have recently been associated with bodily self-consciousness (BSC). Similarly, growing evidence suggests that the lateral parietal cortex is crucial for the subjective aspects of episodic autobiogra ...

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

Olaf Blanke, Fosco Bernasconi, Andrea Serino, Nathan Quentin Faivre, Jean-Paul Noel, 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 ...

Temporal Dissociation of Neocortical and Hippocampal Contributions to Mental Time Travel Using Intracranial Recordings in Humans

Olaf Blanke

In mental time travel (MTT) one is "traveling" back-and-forth in time, remembering, and imagining events. Despite intensive research regarding memory processes in the hippocampus, it was only recently shown that the hippocampus plays an essential role in e ...

Insula mediates heartbeat related effects on visual consciousness

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

Interoceptive signals, such as the heartbeat, are processed in a network of brain regions including the insular cortex. Recent studies have shown that such signals modulate perceptual and cognitive processing, and that they impact visual awareness. For exa ...

Sensorimotor Induction of Auditory Misattribution in Psychosis is Linked to Neural Disconnectivity

Olaf Blanke, Alessandra Griffa, Kim Do, Patric Hagmann, Andrea Serino, Roy Salomon, Giulio Rognini, Silvia Marchesotti, Pierre Progin

Background: Schneiderian first rank symptoms (FRS) are characterized by a diminished demarcation of self-other boundaries, causing misattribution of self-generated thoughts and actions to external sources. We have shown that introducing sensorimotor predic ...

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

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

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, Roberta Ronchi, Javier Bello Ruiz, Marta Lukowska

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 ...

Spatiotemporal dynamics of visual vertical judgments: early and late brain mechanisms as revealed by high-density electrical neuroimaging

Olaf Blanke, Christophe Lopez, Manuel Mercier, Pär Halje

Constructing and updating an internal model of verticality is fundamental for maintaining an erect posture and facilitating visuo-spatial processing. The judgment of the visual vertical (VV) has been intensively studied in psychophysical investigations and ...

Attenuated asymmetry of functional connectivity in schizophrenia: A high-resolution EEG study

Martin Hasler, Mahdi Jalili, Kim Do, Reto Meuli

The interhemispheric asymmetries that originate from connectivity-related structuring of the cortex are compromised in schizophrenia (SZ). Under the assumption that such abnormalities affect functional connectivity, we analyzed its correlate-EEG synchroniz ...

Induction of an illusory shadow person

Olaf Blanke

Stimulation of a site on the brain's left hemisphere prompts the creepy feeling that somebody is close by. The strange sensation that somebody is nearby when no one is actually present has been described by psychiatric and neurological patients, as well as ...
