Psychometrics of Disembodiment and Its Differential Modulation by Visuomotor and Visuotactile Mismatches

Altered states of embodiment are fundamental to the scientific understanding of bodily self consciousness. The feeling of disembodiment during everyday activities is common to clinical conditions; however, the direct study of disembodiment in experimental ...

Experimentally induced limb-disownership in mixed reality

Oliver Alan Kannape, Bigna Lenggenhager

The seemingly stable construct of our bodily self depends on the continued, successful integration of multi sensory feedback about our body, rather than its purely physical composition. Accordingly, pathological disruption of such neural processing is link ...

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 ...

Multisensory conflicts modulate spatial aspects of bodily self-consciousness

Seeing and identifying with a virtual body decreases pain perception

Olaf Blanke, Bigna Lenggenhager, Roland von Känel

Pain and the conscious mind (or the self) are experienced in our body. Both are intimately linked to the subjective quality of conscious experience. Here, we used virtual reality technology and visuo-tactile conflicts in healthy subjects to test whether ex ...

How vestibular stimulation interacts with illusory hand ownership

Olaf Blanke, Christophe Lopez, Bigna Lenggenhager

Artificial stimulation of the peripheral vestibular system has been shown to improve ownership of body parts in neurological patients, suggesting vestibular contributions to bodily self-consciousness. Here, we investigated whether galvanic vestibular stimu ...

Seeing the body modulates audiotactile integration

Olaf Blanke, Jane Aspell, Bigna Lenggenhager

Audiotactile integration has been studied using various experimental setups but so far crossmodal congruency effects (CCEs) have not been found for tactile targets paired with auditory distractors. In the present study we investigated whether audiotactile ...

Keeping in touch with one's self: multisensory mechanisms of self-consciousness

Olaf Blanke, Jane Aspell, Bigna Lenggenhager

BACKGROUND: The spatial unity between self and body can be disrupted by employing conflicting visual-somatosensory bodily input, thereby bringing neurological observations on bodily self-consciousness under scientific scrutiny. Here we designed a novel par ...

Multisensory mechanisms underlying bodily self-consciousness

Bigna Lenggenhager

Recent philosophical and neuroscientific theories converge on the assumption that the basic foundations of self-consciousness lie in those brain systems that represent the body. Neurological cases in which this basic bodily self-consciousness is disturbed ...

The timing of temporoparietal and frontal activations during mental own body transformations from different visuospatial perspectives

Olaf Blanke, Bigna Lenggenhager

The perspective from where the world is perceived is an important aspect of the bodily self and may break down in neurological conditions such as out-of-body experiences (OBEs). These striking disturbances are characterized by disembodiment, an external pe ...
