recognition, for example) which might be generically similar across subjects. There were several examples of rather dramatic similarity between the portraits of two sites for the same epoch in the RO data (Figure 1). Since these sites are on opposite sides of the head, hemispheric synchronization is strongly suggested. This can be confirmed by superimposing the raw EEG records, noting the high degree of overlap (Figure 2). Such apparent synchronization might have resulted from head-movement artifacts, which affect all sites similarly and are strong enough to swamp the normally weaker brain waves. However, this explanation is easily rejected by inspecting adjacent epochs. Another possible explanation is that the apparent synchronization is due to entrainment. This would be exciting if true, since it is the basic presupposition of the Hemi-Sync technology. In order to test this hypothesis directly, one would need simultaneous EEG and Hemi-Sync stimulus records, making it possible to investigate realtime correlations. Unfortunately, this was not part of the brain mapping protocol. In any case, that explanation is ruled out for examples of synchrony in the RO file which occur in the baseline epochs, when there is no auditory stimulus at all. Yet another hypothesis might be suggested. Hemispheric synchrony is known to be correlated with certain relaxed states, quite independently of external stimuli, as was amply demonstrated

by the TMI research report of Mohammad Sadigh in 1990. [See HEMI-SYNC JOURNAL, Fall 1990, Vol. VIII, No. 4.] [See: Topics/Physiology/Brain Mapping] Perhaps subject RO is simply adept at reaching such states? There may well be some evidence for this, though it would have required the subject’s permission to report it here. Whatever the explanation, it is noteworthy that the portraits in question bear an interesting resemblance to the Focus 15 Hemi- Sync signal pattern, which is certainly consistent with the correlation between hemispheric synchrony and relaxed states. This interim report only scratches the surface. I look forward to working more closely with TMI lab personnel over the coming months, and to reporting more fully at the 1992 Professional Seminar.
