This study investigates eight case reports of spontaneously emerging, brief episodes of vivid altered states of Selfhood (ASoSs) that occurred during mental exercise in six long-term meditators by using a neurophenomenological electroencephalography (EEG) approach. In agreement with the neurophenomenological methodology, first-person reports were used to identify such spontaneous ASoSs and to guide the neural analysis, which involved the estimation of three operational modules of the brain self-referential network (measured by EEG operational synchrony). The result of such analysis demonstrated that the documented ASoSs had unique neurophenomenological profiles, where several aspects or components of Selfhood (measured neurophysiologically and phenomenologically) are affected and expressed differently, but still in agreement with the neurophysiological three-dimensional construct model of the complex experiential Selfhood proposed in our earlier work (Fingelkurts et al. in Conscious Cogn 86:103031. https://doi.org/10.1016/j.concog.2020.103031, 2020).

本研究通过使用神经现象学脑电图 (EEG) 方法调查了 6 名长期冥想者在心理锻炼期间发生的自发性、短暂的生动改变的自我状态 (ASoSs) 的案例报告。与神经现象学方法一致，第一人称报告被用来识别这种自发的 ASoS 并指导神经分析，这涉及大脑自我参照网络的三个操作模块的估计（通过 EEG 操作同步性测量）。这种分析的结果表明，记录的 ASoS 具有独特的神经现象学特征，其中自我的几个方面或组成部分（神经生理学和现象学测量）受到影响并以不同方式表达，
