Pre-movement sensorimotor oscillations shape the sense of agency by gating cortical connectivity

Olaf Blanke, Bruno Herbelin, Nathaniel Evans, Bastien Orset

Our sense of agency, the subjective experience of controlling our actions, is a crucial component of self-awareness and motor control. It is thought to originate from the comparison between intentions and actions across broad cortical networks. However, th ...

Deep-learning models of the ascending proprioceptive pathway are subject to illusions

Olaf Blanke, Alexander Mathis, Merkourios Simos, Adriana Perez Rotondo, Florian Axel Raphaël David

Proprioception is essential for perception and action. Like any other sense, proprioception is also subject to illusions. In this study, we model classic proprioceptive illusions in which tendon vibrations lead to biases in estimating the state of the body ...
