Abnormal self-location and vestibular vertigo in a patient with right frontal lobe epilepsy

Olaf Blanke, Christophe Lopez, Lukas Heydrich

We describe the case of a 33-year-old man with complex partial seizures characterized by the feeling of being projected outside his body, including dissociation of "mind and self from body" (disembodiment), followed by vestibular vertigo due to right front ...

Illusory own body perceptions: case reports and relevance for bodily self-consciousness

Olaf Blanke, Sebastian Dieguez Falcon, Lukas Heydrich

Neurological disorders of body representation have for a long time suggested the importance of multisensory processing of bodily signals for self-consciousness. One such group of disorders--illusory own body perceptions affecting the entire body--has been ...

The influence of sex and empathy on putting oneself in the shoes of others

Olaf Blanke, Christine Mohr

We tested whether putting oneself in the shoes of others is easier for women, possibly as a function of individuals' empathy levels, and whether any sex difference might be modulated by the sex of presented figures. Participants (N=100, 50 women) imagined ...

Quantifying effects of exposure to the third and first-person perspectives in virtual-reality-based training

Daniel Thalmann, Frédéric Vexo, Patrick Salamin, Ravi Tej Sai Giridhar Tadi, Olaf Blanke

In the recent years, usage of the third-person perspective (3PP) in virtual training methods has become increasingly viable and despite the growing interest in virtual reality and graphics underlying third-person perspective usage, not many studies have sy ...

How vestibular stimulation interacts with illusory hand ownership

Olaf Blanke, Bigna Lenggenhager, Christophe Lopez

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 ...

Carbon outclasses wood in racket paddles: Ratings of expert and intermediate tennis players

Véronique Michaud, Christian Fischer, Michael Herzog, Olaf Blanke

Wooden racket paddles were modified with rubber and carbon fibre laminates and their differences tested in terms of flexural, damping, and coefficient of restitution properties. Four rackets types were designed: a wood reference, wood with rubber, carbon f ...

Seeing the body modulates audiotactile integration

Olaf Blanke, Bigna Lenggenhager, Jane Aspell

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 ...

Feeling in control of your footsteps: Conscious gait monitoring and the auditory consequences of footsteps

Martin Vetterli, Fritz Menzer, Christof Faller, Olaf Blanke, Pär Halje

A fundamental aspect of the “I” of conscious experience is that the self is experienced as a single coherent representation of the entire, spatially situated body. The purpose of the present study was to investigate agency for the entire body. We provided ...

The limits of agency in walking humans

Ravi Tej Sai Giridhar Tadi, Olaf Blanke, Oliver Alan Kannape

An important principle of human ethics is that individuals are not responsible for actions performed when unconscious. Recent research found that the generation of an action and the building of a conscious experience of that action (agency) are distinct pr ...

The 'intrinsic' system in the human cortex and self-projection: a data driven analysis

Olaf Blanke

Information received by the human cortex is supplied by two main sources: extrinsic stimuli delivered by the external environment and intrinsic information regarding the body and self. We reanalyzed electrophysiological data involving the same external sti ...

Mental imagery of self-location during spontaneous and active self-other interactions: an electrical neuroimaging study

Olaf Blanke, Manuel Mercier

Substantial data from the cognitive neurosciences point to the importance of bodily processing for the development of a comprehensive theory of the self. A key aspect of the bodily self is self-location, the experience that the self is localized at a speci ...

Visual capture and the experience of having two bodies

Olaf Blanke, Jane Aspell, Lukas Heydrich

The experience of singularity of the conscious self may break down in heautoscopy. In heautoscopy patients see a double or doppelganger of themselves. Moreover, the self may be experienced as reduplicated—existing at two or even more locations simultaneous ...

Mental imagery for full and upper human bodies: common right hemisphere activations and distinct extrastriate activations

Olaf Blanke, Silvio Ionta, Christine Mohr

The processing of human bodies is important in social life and for the recognition of another person's actions, moods, and intentions. Recent neuroimaging studies on mental imagery of human body parts suggest that the left hemisphere is dominant in body pr ...

First person experience of body transfer in virtual reality

Mel Slater, Olaf Blanke

BACKGROUND: Altering the normal association between touch and its visual correlate can result in the illusory perception of a fake limb as part of our own body. Thus, when touch is seen to be applied to a rubber hand while felt synchronously on the corresp ...

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

Olaf Blanke, Bigna Lenggenhager, Jane Aspell

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 ...

Impaired Imagery for Upper Limbs

Olaf Blanke

The brain processes associated with mental imagery have long been a matter of debate. Neuroimaging and neuropsychological studies have yielded diverging evidence of mental transformation activating the right hemisphere, the left hemisphere, or both. Here, ...

Gender bending: auditory cues affect visual judgements of gender in biological motion displays

Olaf Blanke

The movement of an organism typically provides an observer with information in more than one sensory modality. The integration of information modalities reduces the likelihood that the observer will be confronted with a scene that is perceptually ambiguous ...

Non-retinotopic feature integration has a neural pace of its own, as revealed by electrical brain imaging

Michael Herzog, Olaf Blanke, Thomas Otto, Manuel Mercier, Gijs Plomp

When elements appear in quick succession they can integrate across space and time. Using high-density EEG techniques we show that such non-retinotopic feature integration is not time-locked to stimulus onset, but has a timing of its own. We presented a cen ...

Mental time in amnesia: evidence from bilateral medial temporal damage before and after recovery

Olaf Blanke

The human mind is continuously involved in "projecting" the self in time in order to process past memories and predict future occurrences. "Self-projection" in time involves episodic and spatial memory, relying on medial-temporal structures, but also engag ...

Deficient mental own-body imagery in a neurological patient with out-of-body experiences due to cannabis use

Olaf Blanke

In the present work, we report repeated out-of-body experiences (OBEs) in a patient with tetraplegia and severe somatosensory loss due to multiple sclerosis and predominant involvement of the cervical spinal cord. OBEs were experienced on a daily basis and ...
