No results posted yet for this study

Summary

The present project exploits brain imaging and neuroscience robotics to investigate the role of quantifiable visual input on the relationship between visuo-tactile integration and body ownership (the feeling that "this" body belongs to "me").

Conditions

  • Behavior and Behavior Mechanisms
  • Body Representation

Interventions

BEHAVIORAL

Visuo-tactile stimulations of the right hand

Participants lay down in the magnetic resonance (MR) scanner are presented with visual stimuli (videos of the virtual rubber hand - visual stroking) simultaneously in real time with tactile stimuli (robotic stroking of the participant's hand - tactile stroking). An MR-compatible robot systematically provides the tactile stroking on the participant's hand. MR-compatible goggles show the visual stroking. Patterns of long and short robotic movements will be provided.
