Neural signatures of visuo-motor integration during human-robot interactions

Hannes Bleuler, Olaf Blanke, Giulio Rognini, Silvia Marchesotti, Fosco Bernasconi

Visuo-motor integration shapes our daily experience and underpins the sense of feeling in control over our actions. The last decade has seen a surge in robotically and virtually mediated interactions, whereby bodily actions ultimately result in an artifici ...

Sensorimotor Induction of Auditory Misattribution in Early Psychosis

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Silvia Marchesotti, Roy Salomon, Andrea Serino, Fosco Bernasconi, Kim Do

Dysfunction of sensorimotor predictive processing is thought to underlie abnormalities in self-monitoring producing passivity symptoms in psychosis. Experimentally induced sensorimotor conflict can produce a failure in bodily self-monitoring (presence hall ...

Imagined paralysis alters somatosensory evoked-potentials

Olaf Blanke, Fred Mast, Christophe Lopez, Estelle Palluel, Silvia Marchesotti

Recent studies employing body illusions have shown that multisensory conflict can alter body representations and modulate low-level sensory processing. One defining feature of these body illusions is that they are sensory driven and thus passive on behalf ...

Sensorimotor Induction of Auditory Misattribution in Psychosis is Linked to Neural Disconnectivity

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Silvia Marchesotti, Roy Salomon, Andrea Serino, Kim Do

Background: Schneiderian first rank symptoms (FRS) are characterized by a diminished demarcation of self-other boundaries, causing misattribution of self-generated thoughts and actions to external sources. We have shown that introducing sensorimotor predic ...

Motor and cognitive brain circuits of brain-machine interactions

Silvia Marchesotti

Brain-machine interfaces (BMIs) allow the user to control an external device such as a robotic arm, a cursor, or an avatar in a virtual world through the real-time decoding of brain signals and without the involvement of the musculoskeletal system. Althoug ...

Quantifying the role of motor imagery in brain-machine interfaces

Hannes Bleuler, Olaf Blanke, Silvia Marchesotti, Andrea Serino, Michela Bassolino

Despite technical advances in brain machine interfaces (BMI), for as-yet unknown reasons the ability to control a BMI remains limited to a subset of users. We investigate whether individual differences in BMI control based on motor imagery (MI) are related ...

Human and Machine Learning in Non-Markovian Decision Making

Walter Senn, Michael Herzog, Elisa Tartaglia, Silvia Marchesotti, Aaron Michael Clarke

Humans can learn under a wide variety of feedback conditions. Reinforcement learning (RL), where a series of rewarded decisions must be made, is a particularly important type of learning. Computational and behavioral studies of RL have focused mainly on Ma ...
