The sensed presence may be facilitated by interhemispheric intercalation: relative efficacy of the Mind's Eye, Hemi-Sync Tape, and bilateral temporal magnetic field stimulation.
After sitting quietly within an acoustic chamber, 30 university men were exposed (singly) to binaural, complex stimulation (Hemi-Sync Tape), synchronized binaural and visual patterns (The Mind's Eye), or transtemporal magnetic fields for 30 min. Experiences were rated at the end of the treatment by questionnaire. The men who received the binaural stimulation (Hemi-Sync Tape) reported more intense sensed presences and ego-alien intrusions than did the other two groups. In a similar second experiment, 18 university women who received the binaural stimulation also reported these experiences. The results support the hypothesis that the sensed presence is facilitated by transient, neuroelectrical intercalation of the temporoparietal lobes and is associated with the intrusion into awareness of the right-hemispheric equivalent of the left-hemispheric sense of self.
