(Hemi-Sync® Journal, Vol. IX, No. 4, Fall 1991) THE MYSTERIES OF HEMI-SYNC® BEYOND BRAIN ENTRAINMENT by Mohammad Sadigh, Ph.D. Micah Sadigh is director of psychology and psychophysiological services at The Gateway Institute, a center for pain and stress management in Bethlehem, Pennsylvania. He practices psychotherapy and biofeedback and is in charge of the center’s neuropsychological laboratory. Computer-assisted brain mapping is his primary area of research. Here, Dr. Sadigh highlights the results of his ongoing independent research with Hemi-Sync. Theoretically, when the two hemispheres function in unison and in synchrony a variety of beneficial effects, both physical and psychological, may ensue. That is why, during the past several years, a number of researchers, clinicians, and entrepreneurs have attempted to develop ways of inducing whole-brain synchrony. Since transcendental meditation takes quite some time to accomplish, and there are no guarantees that it will work, and because the meditation effect appears to be limited to a specific frequency band, more and more people are trying to combine the new and old technologies to attain hemispheric synchrony. After attending the GATEWAY VOYAGE® I began to conduct a series of studies to determine if Hemi-Sync was an effective way of achieving hemispheric synchrony. The first Focus 10

study, conducted at The Gateway Institute’s neuropsychological laboratory, provided me with the initial proof that Hemi-Sync does work. Hemi-Sync entrained the brain of a subject to achieve and maintain a full state of hemispheric synchrony within the theta range. Research shows that as meditation subjects move toward the theta stage, they tend to either fall asleep or rapidly move toward higher frequencies. The Hemi-Sync signal appears to help overcome such tendencies. During the second and third studies, a subject listened to Focus 12 tapes. The results of both studies showed significant bilateral synchronization in the beta range. Also, at the end of the third study, and at the end of the Hemi-Sync introduction, the subject was asked to “open the Access Channel,” a specific command used in the HUMAN PLUS tape series, and which prepares the listener to learn new cognitive tasks. For the first time, I witnessed a nonmeditator achieving whole-brain synchrony without the use of a tape or the Hemi-Sync frequencies. This was most important. It suggested that perhaps, after exposure to the signal for a period of time, the subject may be capable of reentering a variety of states of consciousness without the use of any external cues or technologies. During this past year, I have conducted a number of new studies with Hemi-Sync. I was especially interested in documenting subjects’ abilities to summon the effects of Hemi-Sync without listening to tapes.
