understand that this region represents more of our sensorimotor processing
areas, but am wondering if I would get more effective results with the
occipital/frontal placement? By more effective, I mean results that will
translate into better results for meditational uses. Or does it matter? I'm
hoping it does not because otherwise I will have to come up with some special
pillow arrangement to accomodate the occipital electrodes.
The probe placement was intended to be compatible with Cade and the Mind Mirror. At the time I was working with Dr. Edith Jurka who studied with Maxwell Cade. I also worked with a neurologist who had a 24 channel Beckman 10/20 system.
Without the occipital connection, you get almost no Alpha waves. At that time I was under the impression that Alpha was a significant piece of information. At this point in time I think the Alpha frequency is a red herring that everyone is chasing. In a previous post I explained how Alpha fits into the total picture.
I believe the frontal lobes hold the key. They are the newest part of the brain. None of the EEG/NF practitioners want to look there because of the artifacts that can exist in that region. It is true there are eye blinks and forehead muscle artifacts, but that is where the conscious mind expresses itself. The O1,O2, C3,C4 etc, are regions of automatic processes that donot change very much as you change you conscious mind focus. You will seeday and night changes in the frontal area as you relax into a meditative state. Another much easier indication is finger tip temperature and skin resistance.
If you are intending to meditate you must sit upright on the edge of the chair or in a lotus position. If you lie down you will fall asleep and miss the whole thing.
Look at my web site. We did some testing in the hospital and measured respiration rate, etc with meditation.

That sounds great. It is kind of similar to the velco band that I made, except
instead of a "button" arrangement, I imbedded the electrode in a small
sandwhiched square of velcro so that it could easily be repositioned. However,
this was not the greatest design, as it put more pressure on the electrode wire
than I realized. Of course I only realized that after it came loose fromthe
cup. :-( I am going to work with the flextrodes for a while longer, but the
next time I find myself staring at them in dismay thinking "there *must* be a
better way!" I will be knocking on your door for help!

BTW--for those looking for Maxwell Cade's book, there is currently one for sale
at Amazon through one of the "marketplace merchants." I'm not sure if they
ship internationally, but it might be worth checking out if you would like to
get a hold of h
book.
