Body image disturbance is one of the main symptoms of eating disorders; however, the neural, basis of this phenomenon is not well understood yet. In the present paper, we review studies investigating the neuronal correlates of visual body perception in anorexia nervosa. We first focus on the well-known parietal lobe contribution to body image processing and its malfunction. Additionally, we focus on the contribution and involvement of the extrastriate and fusiform body area in eating disorders, especially anorexia nervosa. The summarized Studies provide first evidence for a reduced activity, volume, and connectivity in brain areas involved and specialized in the Visual processing of human bodies. In general, the reviewed studies provide evidence for abnormalities in body-processing brain areas in anorexia nervosa, indicating two structures in the brain that are involved: early Stages of body processing in the visual extrastriate cortex and later stages in the parietal cortex.
