“Seeing oneself”: a case of autoscopy

Autoscopy is the experience of seeing an image of one’s body in external space. We describe the case of a patient who reported longstanding autoscopic hallucinations following post-eclamptic brain damage. The MR scan demonstrated damage involving the occipital cortex and the basal ganglia bilaterally. We hypothesize that the image was the result of aberrant plasticity mechanisms involving cortical areas that play a central role in high-order body or representation of oneself.
