Guest guest Posted April 10, 2012 Report Share Posted April 10, 2012 As a woman, I also get HEG gains when I have a hot flash. I stop the training and wait until it subsides. But I'd be curious also as to whether the gain reflects an oxygen surge. I believe if you click capture baseline again, the highest gain meter normalizes.

No matter what the threshold setting on Instrument 1 or the current ratio on Instrument 2(either above or below baseline ratio), I still get a continuous or near continuous reward tone on AI rise as well as % current and session AI. I also get reward tone even if HEG gain is rising or falling. I don't understand this. What is the relationship between AI and HEG gain?

Guest guest Posted April 11, 2012 Report Share Posted April 11, 2012 ,Let's verify that everything is being done properly first (always best to rule out equipment problems or operator error before blaming the brain):1. Make sure that the nIR headband is sealing at the top. When it is on your head, ask someone to stand beside you (seated) and look down where the headband meets the forehead on top. Of course the headband should be running in the valley across your forehead between the supra-orbital ridges (the rise in the bone above the eyes) and the top of the forehead. If your helper can see red light from the inside of the headband (you are wearing it with the blue part outside, the white velcro dot visible and over the training area), try adjusting it on your forehead to see if you can get it to seal. In many cases the best thing to do is to buy a sweat band like tennis player use. Place that over the HEG headband so the bottom half of the sweatband covers the top half of the HEG band, and the top half of the sweatband is on your head. This will seal the opening so the readings of red light reflected from the surface of the brain are more accurate. You can also use a baseball cap to seal the opening. 2. Start the session by clicking the Play button. Don't go into your focus state initially. Let the graph create a baseline on Instruments2. The graph often starts by going way up, then dropping down, then it starts to bounce--all this within the first 30 seconds, the first column of the graph. As soon (nearly always within 30 seconds) as you have a couple points on the graph at about the same level, click the Capture Baseline button. This will reset the timer and place a number in the baseline meter. A second later, click the Reset Max button below the Capture Baseline button. This will reset both the maximum gain meter and the AI score button, so you can see what the highest percent increase you achieved during the session is and also the number of seconds you stayed with AI at 100% during the segment. 3. NOW start focusing. Don't think, don't try, don't judge. Just focus intently on a single point and see what makes the graph go up. I like to focus on the point where the graph comes out of the right side of the window, right on that point so I see immediately when it is going up or starting to fall. Some people like to use the orange feedback bars on the left side of the screen, seeing if they can get the AI bargraph up to 100% and keep it there. You can also track your ability to sustain increasing metabolic activity by watching the orange graph at the bottom of the page. The more orange it is, the more consistent your focus. 4. The Instruments1 page, with the video or DVD or whatever shows the same graph as Instruments2, but it is smaller and harder to read. The bargraph on the right side measures the same ratio as the graphs (the red/infrared ratio). If you are using this, it controls the DVD playback (if you have clicked the Control button to turn it red beneath the DVD player screen) or video or game playback. That sets when you capture baseline. If I use that page, I keep my cursor over the A->M button at the bottom of the bargraph. Every time the bar in the graph is clearly above the target line, click A->M. This will keep your target line rising while you are raising your ratio, so when you start to drop the video/game will pause until you raise it again. I've attached the latest versions of the files in an rar file which will need to be unpacked. There is a tracking form in it as well. Note your baseline, your highest gain and your AI Score for Left, Center and Right. If you find any of your baseline values are very high--above 100 for example--you may actually want to figure out how to let the graph go down first. The AI (Attention Index) measures the stability of increase during training. It takes the most recent " X " number of measures (don't know the number). As long as each reading is equal to or higher than the previous one, the AI stays at 100%. As soon as one (or more) drop below their previous values the percent begins to fall. In our design, AI above 70% will trigger the tone (which can be turned off or turned down if you choose by going to the Tools menu in BE, choosing Volumes, and unchecking the Continuous MIDI or using the slider bar to reduce its volume.) When AI is at 100%, the ratio graph will be and the current percent gain will also be rising. But in many cases the current percent will be lower than the highest gain, so the highest gain percent may NOT change. I prefer to focus people on the graph, since that shows both the immediate response and the trend over time. Use the maximum percent gain and the AI score as end-of-session measures. Any time you see the graph starting to trend down, and the client can't turn it, pause the session and move to another site. The key rule with HEG is DON'T OVERTRAIN. BTW, there is a very good Wikipedia article on HEG at http://en.wikipedia.org/wiki/Hemoencephalography (we should probably link to it on the website). pete-- Van Deusenpvdtlc@... http://www.brain-trainer.comUSA 678 224 5895BR 47 3346 6235The Learning Curve, Inc.

Guest guest Posted April 11, 2012 Report Share Posted April 11, 2012 Wow! Very comprehensive and a lot to digest. Thanks, Pete, for your expertise and time. You are very generous in mentoring us as you do for so little from us. Thank you!! Mike > > > ** > > > > > > Pete, > > > > Trying to understand your NIR HEG designs.
