Pre-stimulus alpha activity modulates long-lasting unconscious feature integration

Michael Herzog, David Pascucci, Maëlan Quentin Menétrey

Pre-stimulus alpha (α) activity can influence perception of shortly presented, low-contrast stimuli. The underlying mechanisms are often thought to affect perception exactly at the time of presentation. In addition, it is suggested that α cycles determine ...

Breathing affects self-other voice discrimination in a bodily state associated with somatic passivity

Olaf Blanke, Giulio Rognini, Nathan Quentin Faivre, Hyeongdong Park, Pavo Orepic

A growing number of studies have focused on identifying cognitive processes that are modulated by interoceptive signals, particularly in relation to the respiratory or cardiac cycle. Considering the fundamental role of interoception in bodily self-consciou ...

The irreducibility of vision: Gestalt, crowding and the fundamentals of vision

Michael Herzog

What is fundamental in vision has been discussed for millennia. For philosophical realists and the physiological approach to vision, the objects of the outer world are truly given, and failures to perceive objects properly, such as in illusions, are just s ...

Learning V1 Simple Cells with Vector Representation of Local Content and Matrix Representation of Local Motion

Yufan Ren

This paper proposes a representational model for image pairs such as consecutive video frames that are related by local pixel displacements, in the hope that the model may shed light on motion perception in primary visual cortex (V1). The model couples the ...

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 ...

TMS-induced control of bodily self-consciousness by combining non-invasive brain stimulation and immersive virtual reality

Matteo Franza

Our brain constantly receives and integrates a flow of sensory and motor information that shapes the way our body is represented. Several experimental approaches have been proposed to alter the body representation, by manipulating exteroceptive or interoce ...

Building perception block by block: a response to Fekete et al

Michael Herzog, Frank Scharnowski, Adrien Christophe Doerig

Is consciousness a continuous stream, or do percepts occur only at certain moments of time? This age-old question is still under debate. Both positions face difficult problems, which we proposed to overcome with a 2-stage model, where unconscious processin ...

Spatiotemporal feature integration within discrete time windows provides evidence for discrete perception

Michael Herzog, Adrien Christophe Doerig, Leila Drissi Daoudi - Kleinbauer

Intuitively, consciousness seems to be a continuous stream of percepts. Here, contrary to intuition, we show evidence for discrete consciousness, occurring only at certain moments of time. We presented a Vernier followed by a sequence of flanking lines on ...

The Architectonic Experience of Body and Space in Augmented Interiors

Olaf Blanke, Andrea Serino, Isabella Maria Pasqualini, Maria Laura Blefari

The environment shapes our experience of space in constant interaction with the body. Architectonic interiors amplify the perception of space through the bodily senses; an effect also known as embodiment. The interaction of the bodily senses with the space ...

Quasi-Continuous Unconscious Processing precedes Discrete Conscious Perception

Michael Herzog, Adrien Christophe Doerig

Consciousness seems to be a smooth, continuous stream of percepts. We are aware of the world at each single moment of time. However, intriguing illusions suggest that the world is not continuously translated into conscious perception. Instead, consciousnes ...

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

Olaf Blanke, Bruno Herbelin, Jane Aspell, Lukas Heydrich

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

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

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, Nathan Quentin Faivre, Roy Salomon

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

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, Aaron Michael Clarke, Lukasz Grzeczkowski

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 ...
