“…Frequently, heautoscopic echopraxia, i.e., the imitation of bodily movements by the double, gives rise to the illusion that it is the doppelgänger that "contains the real mind" (e.g., Lukianowicz, 1958, cases A and D;Dewhurst and Pearson, 1955, cases 1 and 2; Brugger et al, 1994). Echopractic movements may sometimes follow actual body movements with a time lag (e.g., Lance, 1976), an observation also reported in patients with supernumerary phantom limbs (Hari et al, 1998) and supporting the notion of the doppelgänger as a "phantom of the entire body" (Brugger, 2006). There is considerable variation in the reported duration of heautoscopy; it may last for seconds or for hours, and even cases of the double as a steady companion are not exceptional (Conrad, 1953;Engerth and Hoff, 1929;Pearson and Dewhurst, 1954).…”

“…Por ejemplo, existe el caso de una mujer que sufrió la ruptura de un aneurisma con una lesión concomitante en el lóbulo frontal en donde ésta percibía tener una "mano ajena" que intentaba ahogarla cuando nadaba en una piscina (Hari, Hänninen, Mäkinen, Jousmäki, Forss, Seppä, & Salonen, 1998). Por otra parte, el procesamiento visual también puede verse alterado debido a una falta de respuesta en el cerebro, tal y como ha sido demostrado en estudios en sujetos sanos en los que se ha administrado un sedante y posteriormente se mide el nivel de oxígeno cerebral (Martin, Thiel, Joeri, Loenneker, Ekatrodramis, Huisman, Henning, & Marcar, 2000); o en pacientes esquizofrénicos con deterioro de la corteza prefrontal (Berlucchi & Aglioti, 1997;Vogeley et al, 1999).…”

“…Hari et al [26] reported a case of a 37-year-old woman who occasionally perceived a third arm and, less frequently, a third leg, after an operation for a ruptured aneurysm, followed by an infarction of the right frontal lobe.…”
