| Popis: | Autoscopic phenomena (AP) are characterized by seeing an image of oneself in extra-personal space. These phenomena are rare and the anatomy of brain regions producing these phenomena is not well defined. We report anatomical electroclinical correlations during a stereoelectroencephalography-recorded seizure with autoscopic hallucination (a form of AP in which the double of oneself is seen from an internal point of view). Seizure onset zone was quantified using the epileptogenicity index method (EI). Maximal EI values were obtained in the left lateral parietal cortex (supramarginal gyrus) and high values were also found in the left posterior-superior insular cortex, left temporo-occipital junction and contralateral inferior parietal lobule. Our case confirms the involvement of the inferior parietal lobule, temporo-parieto-occipital junction and posterior insula in the genesis of autoscopic hallucination. |
