Out-of-Body Experience and Autoscopy of Neurological Origin

Blanke, Olaf.; Landis, Theodor.; Spinelli, Laurent.; Seeck, Margitta. • 2004 • Brain

Six neurological patients experiencing out-of-body experiences (OBE) or autoscopy (AS) were studied with phenomenological interviews, EEG, electrical cortical stimulation, neuropsychological testing, and neuroimaging. In 5 of 6 patients, brain damage or dysfunction localized to the temporo-parietal junction (TPJ). OBE was always preceded by supine position and accompanied by vestibular sensations (elevation, floating); in Patient 3, OBE was reliably induced by electrical stimulation at the right TPJ at 3.5 mA. The authors propose that OBE requires both a disintegration of proprioceptive-tactile-visual body information and a vestibular dysfunction disrupting the relationship between personal and extrapersonal space, both due to paroxysmal TPJ dysfunction.

Stimulating illusory own-body perceptions

Blanke, Olaf.; Ortigue, Stéphanie.; Landis, Theodor.; Seeck, Margitta. • 2002 • Nature

Focal electrical stimulation of the right angular gyrus in a 43-year-old epilepsy patient undergoing presurgical evaluation reproducibly induced out-of-body experiences. At lower currents (2.0–3.0 mA), vestibular sensations of sinking or falling were reported; at 3.5 mA, the patient described seeing herself lying in bed from above, floating near the ceiling. The same site also induced complex somatosensory illusions: legs appearing shorter, arms seeming to move toward the face. OBE visual content was restricted to body parts also subject to somatosensory distortion, and the epileptic focus was >5 cm away. These findings suggest OBEs result from a failure to integrate somatosensory and vestibular information at the temporo-parietal junction.
