Abstract

Visual information of our own body and other bodies is an important source of information which guides our actions and perception. Using fMRI we study the location and characteristic of brain areas which process visual body information. The investigation of body- and body-part-selective brain areas has so far focused on areas in the occipitotemporal cortex [such as extrastriate body area(s) (EBA)]. In this study we specifically focus on the parietal cortex which is known to be involved in action planning and multi-sensory perception. In a first experiment, we employed an fMRI block design and presented images of hands, feet, objects and faces. We found that in addition to the known occipitotemporal areas, also parietal areas where more active when pictures of body parts where presented as compared to objects and faces. In a second experiment, we investigated the coding for body-part orientation in parietal and occipitotemporal body-partselective areas. The results from both experiments will be discussed.
