Abstract Body ownership refers to the perceptual experience of a body or body part as one's own. Integration of signals from different sensory modalities is considered to play a central role in the emergence of this fundamental experience. This chapter reviews behavioral and neuroimaging studies that have investigated the multisensory processes and neural mechanisms involved in body ownership. First, we will discuss behavioral studies that have used different versions of the rubber hand illusion to identify the spatial, temporal, and other multisensory congruence rules that determine ownership of a limb. Thereafter, we will review neuroimaging studies that have linked changes in limb ownership to changes in neural activity in specific multisensory areas in the frontal and parietal association cortices. Finally, we will discuss studies that have used full-body ownership illusions to examine how the sense of ownership of an entire body arises and that have clarified the role of multisensory processes in this perceptual phenomenon. Collectively, the available data suggest an important role for multisensory integration in body ownership; the data also provide substantial support for the hypothesis that body ownership can be seen as multisensory perception of one's own limbs and one's entire body.
