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 ...

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 ...

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 ...

Multisensory mechanisms in temporo-parietal cortex support self-location and first-person perspective

Olaf Blanke, Dominique Chapuis, Roger Gassert, Lukas Heydrich, Silvio Ionta, Bigna Lenggenhager, Michaël Mouthon

Self-consciousness has mostly been approached by philosophical enquiry and not by empirical neuroscientific study, leading to an overabundance of diverging theories and an absence of data-driven theories. Using robotic technology, we achieved specific bodi ...

Alpha band oscillations correlate with illusory self-location induced by virtual reality

Olaf Blanke, Bigna Lenggenhager, Pär Halje

Neuroscience of the self has focused on high-level mechanisms related to language, memory or imagery of the self. However, recent evidence suggests that low-level mechanisms such as multisensory and sensorimotor integration may play a fundamental role in s ...

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 ...

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 ...

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 ...

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 ...
