ABSTRACT
The portion of space that closely surrounds our body parts is termed peripersonal space, and it has been shown to be represented in the brain through multisensory processing systems. Here, we tested whether voluntary actions, such as grasping an object, may remap such multisensory spatial representation. Participants discriminated touches on the hand they used to grasp an object containing task-irrelevant visual distractors. Compared with a static condition, reach-to-grasp movements increased the interference exerted by visual distractors over tactile targets. This remapping of multisensory space was triggered by action onset and further enhanced in real time during the early action execution phase. Additional experiments showed that this phenomenon is hand-centred. These results provide the first evidence of a functional link between voluntary object-oriented actions and multisensory coding of the space around us.
