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 ...

Is the perception of illusions abnormal in schizophrenia?

Michael Herzog, Maya Roinishvili, Lukasz Grzeczkowski, Albulena Jashari-Shaqiri, Fred Mast

There seems to be no common factor for visual perception, i.e., performance in visual tasks correlates only weakly with each other. Similar results were found with visual illusions. One may expect common visual factors for individuals suffering from pathol ...

Virtual Reality as a Vehicle to Empower Motor-Cognitive Neurorehabilitation

Andrea Serino

In this paper, we advocate the combination of four key ingredients that we believe are necessary to design long-lasting effective treatments for neurorehabilitation: (i) motor-cognitive training, (ii) evidence-based neuroscience principles, in particular t ...

From multisensory integration in peripersonal space to bodily self-consciousness: from statistical regularities to statistical inference

Olaf Blanke, Andrea Serino, Jean-Paul Noel

Integrating information across sensory systems is a critical step toward building a cohesive representation of the environment and one's body, and as illustrated by numerous illusions, scaffolds subjective experience of the world and self. In the last year ...

Unconscious integration of multisensory bodily inputs in the peripersonal space shapes bodily self-consciousness

Olaf Blanke, Andrea Serino, Roy Salomon, Nathan Quentin Faivre, Jean-Paul Noel, Marta Lukowska

Recent studies have highlighted the role of multisensory integration as a key mechanism of self-consciousness. In particular, integration of bodily signals within the peripersonal space (PPS) underlies the experience of the self in a body we own (self-iden ...

Time Slices: What Is the Duration of a Percept?

Michael Herzog, Frank Scharnowski

We experience the world as a seamless stream of percepts. However, intriguing illusions and recent experiments suggest that the world is not continuously translated into conscious perception. Instead, perception seems to operate in a discrete manner, just ...

Changing motor perception by sensorimotor conflicts and body ownership

Olaf Blanke, Roy Salomon, Michiel van Elk, Joan Llobera Mahy, Natalia Fernandez

Experimentally induced sensorimotor conflicts can result in a loss of the feeling of control over a movement (sense of agency). These findings are typically interpreted in terms of a forward model in which the predicted sensory consequences of the movement ...

Tell me about your Ponzo and I will tell you who you are

Michael Herzog, Lukasz Grzeczkowski, Aaron Michael Clarke, Fred Mast

Unlike in cognition, audition and somatosensation, performance between various visual tasks does not correlate. Surprisingly, even tasks that appear similar, like visual acuity and line bisection task do not share much common variance. Similar results were ...

Balancing the Self

Mariia Kaliuzhna

The vestibular system is composed of otolith organs and semi-circular canals that encode linear and angular accelerations, as well as the position of the head with respect to gravity. Thus, the detection of self-motion, the distinction between self- and ob ...

Visuo-vestibular mechanisms of bodily self-consciousness

Joachim Jean-Marie Forget

Bodily self-consciousness is linked to multisensory integration and is particularly dependent on vestibular perception providing the brain with the main sensory cues about body motion and location in space. Vestibular and visual inputs are permanently bala ...
