The neural correlates of topographical disorientation-a lesion analysis study

Olaf Blanke, Lukas Heydrich, Eva Blondiaux

Topographical disorientation refers to the selective inability to orient oneself in familiar surroundings. However, to date its neural correlates remain poorly understood. Here we use quantitative lesion analysis and a lesion network mapping approach in or ...

REM sleep and muscle atonia in brainstem stroke: A quantitative polysomnographic and lesion analysis study

Lukas Heydrich, Eva Blondiaux

Important brainstem regions are involved in the regulation of rapid eye movement sleep. We hypothesized that brainstem stroke is associated with dysregulated rapid eye movement sleep and related muscle activity. We compared quantitative/qualitative polysom ...

Common and distinct brain networks of autoscopic phenomena

Olaf Blanke, Lukas Heydrich, Eva Blondiaux

Objective Autoscopic phenomena (AP) are illusory own body reduplications characterized by the visual perception of a second own body in extrapersonal space, and include three main forms: autoscopic hallucination (AH), heautoscopy (HAS) and out-of-body-expe ...

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 ...

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 ...

Illusory hand ownership in a patient with personal neglect for the upper limb, but no somatoparaphenia

Olaf Blanke, Andrea Serino, Roberta Ronchi, Lukas Heydrich

The symptoms of patients with left personal neglect are characterized by inattention towards contralesional (left) body parts while at the same time explicitly ascertaining ownership for the neglected hemibody. It is currently unknown if personal neglect i ...

Cardio-visual full body illusion alters bodily self-consciousness and tactile processing in somatosensory cortex

Olaf Blanke, Lukas Heydrich, Bruno Herbelin, Jane Aspell

Prominent theories highlight the importance of bodily perception for self-consciousness, but it is currently not known whether this is based on interoceptive or exteroceptive signals or on integrated signals from these anatomically distinct systems, nor wh ...

Lateralising value of experiential hallucinations in temporal lobe epilepsy

Olaf Blanke, Lukas Heydrich, Nathaniel Evans

Objectives Ever since John Hughlings Jackson first described the so-called 'dreamy state' during temporal lobe epilepsy, that is, the sense of an abnormal familiarity (deja vu) or vivid memory-like hallucinations from the past (experiential hallucinations) ...

Crossed somatoparaphrenia: an unusual new case and a review of the literature

Olaf Blanke, Lukas Heydrich

Somatoparaphrenia is a delusional misidentification and confabulation of body parts, usually arm or hand, opposite to a cerebral lesion, generally of the "minor" right hemisphere. There is some controversy concerning lesion site ( fronto-parietal; parieto- ...

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

Olaf Blanke, Lukas Heydrich, Michiel van Elk, Bigna Lenggenhager

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 ...
