Re: finding the correct bandwidth

[Guest guest]

Sharrie,I'm interested in what you've written here.  My experience has always been that if the client fidgeted and had difficulty sitting still, etc., the frequency was too HIGH--not low; and that falling asleep in the chair usually meant an excessively LOW frequency.  Was this just a mis-type, or is that what you actually find?

Thanks,Pete-- Van Deusenpvdtlc@...http://www.brain-trainer.comUSA 305 433 3160BR 47 3346 6235

The correct frequency is actually very easy to find in children by watching thier physical signs. Start your trainging at C4A2 witha  bandwidth that you believe is close to what you think it should be. If the child drops their shoulders and starts fallign asleep then your bandwidth may be too high. If the child sits forward in thier seat and looks antsy and want s to move about then you may have the bandwidth too low. When the child is sitting upright in a relaxed sated, tuned into the converstaion iin the room with good eye contact and being in the here and now then you have thecorrect bandwidth!

Pete,Did Sharrie answered to you?  I was so interested and waited for her answer.  I even asked her backchannel but didn't get her answer.Jo

,Thanks.  Actually bandwidth has nothing to do with training frequency, as you suggest.  An amplifier has a bandwidth (e.g. it will respond to frequencies from 0.1 Hz to 56Hz).  When we train, we train frequencies or frequency bands.

Hi, Sharrie and Pete,

Im just chiming in with a suggestion for clarification of terminology. Sharrie, you used the terms: " bandwidth " ; " bandwidth too high " ; " bandwidth too low " ; and " finding the right frequency " . Pete responded with an observation about " frequency " .

I apologize if this sounds like kindergarten stuff and I do not say this to imply that I know and you do not know... My interest is only a reminder to use terminology consistently, Thanks

First " bandwidth " and " frequency " are not the same. Frequency is commonly the number of cycles per second for any particular cyclic function, like a brainwave, ocean wave, radio wave . . . etc. Bandwidth is commonly the width of the spread in frequency from the lowest (or slowest, and also the lowest energy) wave function frequency to the highest (the fastest, and the highest energy) wave function frequency of concern.... i.e Bandwidth = highest frequency minus lowest frequency within the range of the definition of the frequency band.

In terms of commonly accepted brainwave frequencies and the associated bandwidths: (these definitions are not absolute and will vary all over the map depending on the presenter)

Frequency Bandwidth Name of frequency Band

100 to 200 Hz 100 Hz Lambda waves

30 to 100 Hz 70 Hz Gamma and HyperGamma waves

13 to 30 Hz 7 Hz Beta waves

8 to 12 Hz 4 Hz Alpha waves

4 to 8 Hz 4 Hz Theta waves

0.5 to 4 Hz 3.5 Hz Delta waves

< 0.5 Hz 0.5 Hz Epsilon waves

Enough..... Huskey

Pete et. al.,To resurrect this issue...  My sense is that the answer may be empirical  --  whatever works, works. I found some old Othmer notes which suggested that if the client was getting drowsy during the session, you might shift to a lower frequency...

" If training R and L separately, you can shift to more right side training, or shift to a lower frequency on the left side. If doing Bipolar training (L minus R), just shift to a lower frequency. "  I also vaguely recall a lecture, wherein the point was made that some " fidgety, squirmy, agitated,  hyperactive " kids/folks may need to be trained at a higher frequency -- which is also counter-intuitive.  The rationale was that the child/folk was getting active to 'fight off' drowsiness which was a result from being trained at too low a frequency.

Hope this is useful, if not muddying of the waters... SitarOn Sun, Jul 24, 2011 at 4:51 PM, pvdtlc <pvdtlc@...> wrote:
