The Science Behind Holosync and Other Neurotechnologies A Revolution in Neuroscience: Tuning the Brain

Science ushered in a new era in our ability to learn, be creative, remember, control our moods, reduce stress, resolve unwanted behavior patterns, and a host of other desirable ends, with the appearance of a remarkable paper by Dr. Gerald Oster, of Mt. Sinai Medical Center, in the October 1973 issue of Scientific American. Oster’s paper, entitled “Auditory Beats in the Brain,” described how pulsations called binaural beats occurred in the brain when tones of different frequencies were presented separately to each ear. As a result, the entire brain became entrained to a frequency equal to the difference between the two tones and began to resonate to that frequency. In other words, Oster discovered a method for what is called entrainment of brain wave patterns. (1) Simultaneously, Robert Monroe, of the Monroe Institute of Applied Sciences, was also investigating binaural beats. In thousands of experiments, using an EEG machine to monitor subjects’ electrical brain wave patterns, Monroe also concluded that he could entrain brain wave patterns using binaural beats. In addition, he noted that the response did not happen only in the area of the brain responsible for hearing, or only in one hemisphere or the other, but rather, the entire brain resonated. The waveforms of both hemispheres exhibited identical frequencies, amplitude, phase, and coherence. Since then, many researchers have verified this phenomenon. Language and speech pathologist Dr. Suzanne Evans Morris, Ph.D., reports Research supports the theory that different frequencies presented to each ear through stereo headphones . . . create a difference tone (or binaural beat) as the brain puts together the two tones it actually hears. Through EEG monitoring the difference tone is identified by a change in the electrical pattern produced by the brain. For example, frequencies of 200 Hz and 210 Hz produce a binaural beat frequency of 10 Hz. Monitoring of the brain’s electricity (EEG) shows that the brain produces increased 10 Hz activity with equal frequency and amplitude of the wave form in both hemispheres. (2)
