2000 Professional Seminar: Neurological Adaptation to Binaural Beating (Skip Atwater)

well. Had I actually done it had I actually shown that when you do sample was complex stimulus, that their overall brainwave patterns do change and go right along with the stimulus measured before measuring them after they come back. Had I actually done it to some, you know, if you add up 1000s of experiences, you add up the kinds of research professional division has been doing out there, using external instruments to measure people's performance. That's changes. And you add this to it and says, looks like we got something together. But there was one other dynamic that I was still worried about. You know, these people did come to the Monroe Institute. And they did go in the booth. And they didn't put the earphones on. Maybe these people were all expert, heavy seat people, and they, you know, could do this anyway. Well, in order to, you know, try to scale that I had three different categories, people who've never heard of Hemi sync tape before, people who had maybe listen to it at home and people who had been to a program here. So I have three different categories to look at there. I had different sex categories, a different time of the day categories, different Myers Briggs test categories. So I had some different parameters to try to answer those kinds of questions. But, you know, getting down to the real crux to the issue is, what if I took a bunch of people, and I put them in the booth, and I didn't play Hemi sync for him? That would be even more interesting to find out. But what doesn't work? What if I get in there? And they have the same kinds of changes, you know, do I really want to know? I mean, if I stopped right here, stop here and say, look, we got pretty good stuff. Do I really want to go there? Well, that's why I brought up that first story that I was talking about. 46:54 In my first experience with Bob and Hemi sync, and I've been to all the programs. And I've been in the booth lots of times. It really works for me, I mean, Hemi sync really works for me. Sounds like a commercial or something. But this driving curiosity is what wanted me to take the next step, I really wanted to know, I didn't want to stop and say, I don't think I'll do that experiment, it might not work out too well. And I really wanted to know. So how do you do that? What do you how do you deal with that? I decided to repeat the experiment with another 20 people. One and the same way, test them the same way. But not give them binaural beats to listen to as a sample of what the first test was as a sample of the sounds in that first test mark, you have a tape there, push go on the tape. 48:12 Those are the kinds of sounds gonna be here little gentle beating in the background. That's the sound on the first tape, the kind of thing they would listen to. Okay, I wanted to repeat the experiment using the same kinds of frequency ranges, but no binaural beats. So as the tones change throughout it, there were no binaural beats, this is what the placebo was. Okay, very similar kind of sound, but no beating. So to find out what happened, we have to go back to the numbers. And here we are, again. Notice besides having a scratch on the slide, this is on the screen or something out there. And I know these are very different. There are no Asterix on these here. None of these are individually significantly different. None of the response to the delta is individually significantly different. And even though there were some increases, yes, there was, in fact, a Pavlovian vestibular response. I just invented that that's not the real term. You know, put on the earphones lay down, you're out of there. Even though there was some of that it didn't reach statistical significance, it was point o seven. Okay, what that means in chart form is this. There was in fact an increase in delta delta, but it was very, very gentle. So I put another set of people through 20 throughout 218 subjects And I found out that their Delta did go up. When you lay down in a darkened room and listen to binaural tones, you tend to drift off. But it did not go up significantly. Did not go up significantly. How about alpha? What happened to alpha? Once again, no, that's not really an asterick. That's a goober on the screen. No changes here. And look at that really high P number here. The changes in alpha, we don't see this nice dip down here during the stimulus conditions. I told these people the same things. They went into the booth, they didn't know whether they were, you know, supposed to go to Planet Xenon or whatever. Listen to the sounds, relax. Don't move. Okay. Same instructions to everybody. 51:09 I was really happy after I did. I was really glad. Now, let's look at some of these other variables here. I don't know how well you can read them. Instantly. All this is written down in your report you can have I had sex differences, time of day differences, experience naive novice and adapt, and temperament differences based on the Myers Briggs. All of us were thinking that obviously people would have had more experience with Hemi sync, they would do really well. They would go in and take their Delta must be higher, their offer would be lower, and so forth and so on. Guess what, it didn't make any difference? The amount of experience you had had didn't make any difference. There was no differences in the Myers Briggs temperament. Now remember that I didn't purposely construct the test with the same amount of males and females saying them out day and night. Same amount in percentages throughout the population. 13% NFC no 21% This did I did not divide up my study population perfectly in these rooms. Okay, I did on time a day because I felt that make a difference. You know, go to sleep. Two o'clock in the afternoon. I thought, man how many people are gonna do it two o'clock in the afternoon in the fall asleep anyway, you know, as it turned out, we all my time, there was a significant difference here was during time of day here for the binaural beat people. And during time of day here, in the first stimulus for the placebo folks. Interestingly though, the Hemi sinkers had deeper Delta, whereas the pm placebos had deeper Delta. I thought everybody would be afternoon would surely create deeper Delta because it turned out we had deeper Delta happening in the a n me sinkers, which I thought was really kind of interesting. But no differences in sex, no differences and expertise. And no differences in temperament. Again, remember the study wasn't balanced percentage wise for temperament. So in review, I did these tests to see whether or not my personal experience the experience of 1000s of others, what we say in our literature, whether it was all just you know, candy, or did Hemi sync really make a difference? Was it there? Was it making something and I found that in the case of delta, these changes that we observe in the brainwaves are in fact related with a Pearson correlation coefficient and a in the case of alpha, we can't say doesn't look in the numbers like we can say for sure that we're taking away the Alpha stimulus cause the reduction in alpha 54:47 are they causative so we use a different statistical regression analysis to see whether causative in the case of delta Yes, the Delta stimulus causes the changes in delta. It's cause To in the Alpha? Probably not, it doesn't reach his significance level to say that taking re Alpha stimulus causes someone to go into alpha. If you think about a little bit, that's probably true by increasing the Delta, that's what pulled the Alpha down. Now, are they considered significant? And the answer is yes, four of six with a P value of point oh one five of six in case of alpha, with a P value of point oh one again, these changes didn't just happen by chance, they were number one related to the stimuli. And number two very significant changes. So are these stimuli, the, you know, ultimate question to the stimuli actually cause us to change our arousal level? Do they put us in a window of brainwave activity that allows us to have these changed? First personal experiences? Well, by doing these two experiments, I think I've probably been able to say, Yes, that's true. They do really do it in my short talk with me secretly works, right. They do really make these changes. I'm giving you a report that says that it's a draft at the top, because I have not yet submitted this for publication. And I would like input from you all about comments that might be made or left out or added to the report here before we submit it for publication. Comparing these two studies, then the placebo with the experimental study in graphic form, which my pointer saying here, in graphic form, we see that in terms of delta, after about 10 minutes of exposure, they jump up here and are very significant, statistically. Whereas in the placebo, they rose up, but not to the threshold of statistical significance. In alpha case, five of the six times they dropped down lower alpha down to statistical significance. And during the placebo test, they did not so there 57:45 way you can go back on when you 57:49 need more papers. When it's already over, it, was it okay? C three C four bipolar or 102. Bipolar. They are common to measure not only alpha in the back of the head, but delta at the top of the head and all the sleep study. Plus there's less artifact generated if those two sites were in the frontal and temporal. So there's a lot of artifacts because I couldn't decide when you when you look at active electrodes, people that do biofeedback, they identify the active electrode, and I couldn't decide over a wide population, well, maybe I should use C three, maybe I should use C four. And when you do bipolar, mathematically, what that says is it subtracts similarities and supposedly gives you a regional focus. 59:01 Positive data using uniform feedback people that use successful buy. Yes, did you say that again? No statement. I'll see if I could do it again. There in the EG hypnosis literature, there have been positive results that have been found using unipolar setups that were not found using bipolar setups, so that it can make a difference though there are other research setups like EEG biofeedback, where they've certainly gotten plenty of successful data from bipolar setups. 59:42 Obviously, since all of this research has been collected and stored in some big pile of bits inside the computer, one could go not this one, but one could go look at all that data from a wider range of possibilities. 1:00:02 Skip one comment or a few comments, one, it seems like very reasonable study, to read and really little bit nicer to use those people. So same is said the same controls, you would have had, you know, better numbers, but, but you still shown what you're going to show, I would 1:00:21 like to see if someone attempts to replicate the study that they do use the same people, what he's talking about is to use a same person studying with two different variables. Here, I use two groups of 20. 1:00:33 But the main thing that your story planned out, that this these numbers don't quite look for was your history. childhood history was predictive to Bob so that you had that experiential thing? Is there any way to get at that, to look back and see if any of these people have had histories versus not in how they responded? 1:00:53 That's a really good question. There are lots of variables that people like to, you know, keep track of they think of, you know, time of day ultradian rhythms, personality differences, neurological disorders, all sorts of things. And it would be very interesting to add to that scale I questionnaire about childhood experiences, or, you know, have you been abducted by a UFO or had a near death experience? Or, you know, there are tests like that, that get out that question. 1:01:34 For work, Skip, as you know, I'm a fan of demonstrating that Hemi sync works. And that's what
