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 from the
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!
Also, I recall you mentioning once that you use the electrode arrangement that
Cade/Wise used -- from occipital to frontal. I have not been using that setup,
primarily because when I am monitoring myself or someone else, they are laying
down. But I don't know if this has a huge impact on the readings that I am
receiving; I have been using a monopolar placement on ears and C3/C4. I
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.
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.
