Inducing out-of-body experiences in hypnosis (H-OBEs) offers an almost unique opportunity to investigate them under controlled conditions. OBEs were induced as an imaginative task in a resting condition (I-OBE) or in hypnosis (H-OBE) in a group of 15 high hypnotizable subjects. A 32-channel EEG was recorded, and the spectral power and imaginary coherence of each frequency band and each couple of electrodes were calculated. At the end of each session, the Phenomenology of Consciousness Inventory (PCI) was administered to assess the phenomenological aspects of the subjects' experience. Significantly higher scores in the altered state, positive affect altered experience, and attention subdimensions of the PCI were reported in H-OBE than in I-OBE, which were associated with a significant decrease of power in beta and gamma band activity in right parieto-temporal derivations. These results suggest that the H-OBE may offer a useful experimental model of spontaneous OBEs.
在催眠中诱导出体经验（H-OBE）提供了一个几乎独一无二的机会，可以在受控条件下对其进行研究。在一组 15 名高催眠易感性的受试者中，通过休息状态下的想象任务（I-OBE）或催眠（H-OBE）来诱导 OBE。记录了一个 32 通道的 EEG，并计算了每个频带和每个电极对的频谱功率和想象相干性。在每次会议结束时，使用意识现象学量表（PCI）来评估受试者体验的现象学方面。报告说，H-OBE 比 I-OBE 中的改变状态、积极影响改变的体验和注意力子维度的得分更高，这与右顶颞导联中β和γ频段活动的功率显著降低有关。这些结果表明，H-OBE 可能提供了一种有用的自发性 OBE 实验模型。
