Abstract

The main question of this thesis is: Can we dissociate multiple body representations in the healthy brain? Patient studies have already shown a dichotomy between the perceptual body representation used for localizing a body part (body image) versus the motoric body representation used for moving a body part (body schema). In a total of 9 chapters possible task dependency of several bodily illusions is investigated. In the first chapters it is shown for the first time that there is indeed a perception-action task dependency of bodily illusions, which is thought to be based on dissociable underlying body representations. However, this main line of reasoning becomes problematic when significant different responses within the same type of task are identified. The risk of dissociating innumerable body representations that this line of reasoning runs are discussed in the last chapters. Finally, a more dynamic angle for investigating dissociable body representations in the healthy brain is suggested, focusing on the question of how these different body representations are created and interact, therefore looking more closely into the weighting of sensory information.
