Autoscopy is the experience in which an individual perceives the surrounding environment from a different perspective, from a position outside of his or her own body.〔Blanke, O., Mohr, C. (2005). (''Out-of-body experience, heautoscopy, and autoscopic hallucination of neurological origin Implications for neurocognitive mechanisms of corporeal awareness and self consciousness'' ). Brain Research Reviews 50: 184-199.〕 Autoscopy comes from the ancient Greek αὐτός ("self") and σκοπός ("watcher"). Autoscopy has intrigued humankind from time immemorial and is abundant in the folklore, mythology, and spiritual narratives of most ancient and modern societies. Cases of autoscopy are commonly encountered in modern psychiatric practice.〔Dening, T. R., Berrios, G. E. (1994). ''Autoscopic phenomena''. ''British Journal of Psychiatry'' 165: 808-817.〕 According to neurological research, autoscopic experiences are hallucinations.〔〔Brugger, P; Regard, M; Landis, T. (1997). ''Illusory reduplication of one’s own body: phenomenology and classification of autoscopic phenomena''. Cognitive Neuropsychiatry 2: 19-38.〕 == Factors == Experiences - are characterized by the presence of the following three factors: * disembodiment, an apparent location of the self outside one's body; * impression of seeing the world from an elevated and distanced visuo-spatial perspective or extracorporeal, but egocentric visuo-spatial perspective; * impression of seeing one's own body from this perspective (autoscopy). Laboratory of Cognitive Neuroscience, École Polytechnique Fédérale de Lausanne, Lausanne, and Department of Neurology, University Hospital, Geneva, Switzerland, have reviewed some of the classical precipitating factors of autoscopy. These are sleep, drug abuse, and general anesthesia as well as neurobiology. They have compared them with recent findings on neurological and neurocognitive mechanisms of the autoscopy. The reviewed data suggest that autoscopic experiences are due to functional disintegration of lower-level multisensory processing and abnormal higher-level self-processing at the temporoparietal junction.〔〔Blanke, O., Castillo, V.
