'Out-of-body' experiences (OBEs) are curious, usually brief sensations in which a person's consciousness seems to become detached from the body and take up a remote viewing position. Here we describe the repeated induction of this experience by focal electrical stimulation of the brain's right angular gyrus in a patient who was undergoing evaluation for epilepsy treatment. Stimulation at this site also elicited illusory transformations of the patient's arm and legs (complex somatosensory responses) and whole-body displacements (vestibular responses), indicating that out-of-body experiences may reflect a failure by the brain to integrate complex somatosensory and vestibular information.
“体外”体验（OBEs）是一种奇特的、通常较为短暂的感觉，在此过程中，一个人的意识似乎与身体分离，并占据一个远距离观察的位置。在此，我们描述了在一名正在接受癫痫治疗评估的患者中，通过对大脑右角回进行局部电刺激反复诱发这种体验的情况。对该部位的刺激还引发了患者手臂和腿部的虚幻变形（复杂躯体感觉反应）以及全身位移（前庭反应），这表明体外体验可能反映了大脑在整合复杂躯体感觉和前庭信息方面的失败。
