LONDON: In a first, Swiss re­searchers have suc­ceeded in recre­at­ing a ghost il­lu­sion in a lab. Pa­tients suf­fer­ing from neu­ro­log­i­cal or psy­chi­atric con­di­tions have of­ten re­ported feel­ing a strange “pres­ence” that is felt but un­seen, akin to a guardian an­gel or a de­mon. Re­searcher Olaf Blanke’s team at Ecole Polytech­nique Fed­erale de Lau­sanne in Switzer­land was able to recre­ate the il­lu­sion of a sim­i­lar pres­ence in the lab and pro­vide a sim­ple ex­pla­na­tion. They showed the “feel­ing of a pres­ence” re­sults from an al­ter­ation of sen­so­ri­mo­tor brain sig­nals, which are in­volved in gen­er­at­ing self­aware­ness by in­te­grat­ing in­for­ma­tion from our move­ments space.
