This paper looks at the fact that perception of our own body is an essential requirement for our daily interaction with the outside world and may also contribute to self consciousness. The paper explores how multisensory representations of body parts and peripersonal space are constructed in the brain through focusing on recent research. The paper looks at multimodal spatial correspondence and the role of posture: neural evidence; multimodal spatial correspondence and the role of posture; evidence from human performance; visuo-tactile interactions in brain damaged patients; rubber hands and virtual bodies; roles of vision and proprioception; modification of visual-tactile spatial interactions by tool-use and coding of visual input about body parts from mirror reflections. The paper concludes that the venerable but traditionally rather vague notion of the body schema can now be related to more mechanistic issues, concerning multisensory spatial integration within peripersonal space and its neural substrates.
