18 origin at the junction of the right angular gyrus with the posterior supe- rior temporal gyrus19 (Figure 1). Figure 1: Brain mechanisms of self-location and first-person perspective Location of brain damage associated with changes in self-location and the experienced ­direction of the first-person perspective in patients suffering from out-of-body experiences (reproduced with permission from Ionta et al., 2011). Based on the frequent association of OBEs with visuo-somatosensory il- lusions, abnormal vestibular sensations20,21 , and the role of the TPJ in multisensory integration22,23 , it has been suggested that OBEs (and abnor- mal self-identification, self-location, and first-person perspective) occur due to disturbed multisensory integration of bodily signals in (peri) personal space (somatosensory, visual and proprioceptive signals) and extrapersonal space (visual and vestibular signals)8,19 . Experimentally-induced altered states of self-consciousness: Video Ergo Sum Recently these clinical insights have been combined with methods from cognitive neuroscience to study bodily self-consciousness. This line of research used video, virtual reality and/or robotic devices in combina- tions with neuroimaging. Several experimental procedures have been de- veloped that employ various visuo-tactile and visuo-vestibular conflicts
