Abstract
... This study aimed to identify an EEG signature for dissociative states, and for 4 sub-factors related to dissociative and altered consciousness type experiences. Resting alpha frequency-matched photic stimulation was used to successfully induce a temporary dissociative state in 23 healthy volunteers. Phenomenological reports were taken using a range of scales and results were clustered into 4 groups of phenomena (detachment, somatosensory changes, mystical/religious experience, visual hallucination). Differences in functional connectivity and network efficiency were identified for each of these groups. Participants reported higher levels of dissociation and anomalous experience under alpha-matched photic stimulation. There were
significant differences in both connectivity and power in the induced dissociative state. There were also notable differences in regional connectivity within clusters of sub-phenomena related to detachment and mystical experience.
