Re: Re: Why can't I get a good connection with my pendants?

When the CH icons are red, that usually indicates a poor connection.  If it is happening on various Pendants, it certainly indicates a problem with connection quality.-- Van Deusenpvdtlc@...

Thanks, Pete. I just don't know why I have so much trouble with my connections. I wish everyone would shave their heads. Maybe I should get a job in a Tibetan monastery.Liz On Thu, Jul 5, 2012 at 9:18 AM, pvdtlc <pvdtlc@...> wrote:

Oh Pete, I wanted to add: when the electrodes are not connected to anything, the pendant is turned on, and BE is saying "connected", (the electrodes are in the pendant and the pendant is, say, on the table), Ch 1 is red and Ch 2 is green! And then, when I place the electrodes on the head, that does not change...ch 1 still red and ch 2 still green, and when I then record, there is a beautiful EEG coming out of ch 2 and ch 1 is crazy spiky noise. Whereas when things are working properly, *both* channels are Green even when the pendant is sitting on the table. So this is why I'm thinking maybe it's more than a poor connection?Liz S.

Liz,Have you eliminated some of the other variables such as switching out cables?  I have had so many bizarre problems with my QDS Excalibur and I just have to very patiently switch out each component until I find what is effecting my signal.  Several times it was my battery pack (don't use rechargeable batteries with a QDS!).  A thought I have would be getting your saline setup out of the way for one test and using some standard disposable electrodes or little gold plated ones, etc etc.

My latest experiment was hooking up everything to my ProComp (instead of the pendant). It said Open to all connections when I used its impedance meter! Meaning No Connections! Then I reconnected to the head using paste instead of saline + headband and voila, a nice signal! So clearly, I have not mastered the art of saline connections.  The experiments continue...

Also, could we have the always-exciting discussion about HAIR? If someone has a lot of hair coming down, and you are putting electrodes on a back area, okay you push the hair to the left and to the right, and down below the electrode is obviously not a problem, but what do you do with the hair that is *above* the electrodes and thus falling down over them (because of, you know, gravity)? Oh another thing I've changed recently is that I bought new electrodes that are flat instead of the cups -- I did that because I wanted shorter electrodes (18 " instead of 36 " ) because I was always getting tangled up in spaghetti and because I was thinking shorter electrodes might give me a better connection -- but -- is it possible that these flat electrodes are harder to get a good connection with?

Here are my new electrodes:http://bio-medical.com/products/silver-flat-eeg-sensor-16-inch.htmland I have " regular " ear clips, silver. They seem fine. (?)

I'm bald, and so were some of the first people I started doing alpha-synchrony training with.  Oh boy when I first started dealing with people who had hair it was a serious pain in the ass!So Liz what I do is take a small daub of 10-20 paste, find the scalp locations I want, then part the hair to the left and right to create a " runway " of scalp.  Sometimes people will have such cumbersome and wispy hair that I use a little more paste and push the hair above the " runway " - up and out of the way.  I don't know if that was helpful but basically I just use 10-20 as a styling product until I have an ample strip of scalp available to me  :-)

I personally love these snap-in electrodes: http://bio-medical.com/products/neurotrode-eeg-sensors-60-pack.html

Well I didn't look up the exact product number but these look similar, the ones I use have a white fabric center not a black one.I just clean them off and reuse them, they last forever and I find them easier to get a clean signal with than the small gold plates.

Wow that's very interesting, but I have a few pendants, one rather newish, others I bought as very old used equipment, and as I said, when I used paste instead of saline the channel worked fine, so I do think my technique of attaching to the scalp is what I need to work on.LizOn Jul 5, 2012, at 8:27 AM, "davidkaus1975" <davidkaus1975@...> wrote:

Liz,

When I first received my pendant I also had a similar problem with Ch 1. After speaking with Pete, I found out it may be a problem with some pocket pendants. I spoke with Bruce from Pocket Neurobics and he had it repaired within a week.

I think it was a solder joint issue.. Does Channel 2 seem to work ok? Are you getting a good signal from Ch2?

I thought I was going crazy when I encountered the problem, I thought I wasn't doing something right..

Listmates,Victory! Using good old paste instead of saline I am now able to train both my son and husband! yay. In case anyone is interested or willing to look at this EEG, I have attached a file of my son's -- this was using a 2-Ch alpha synchrony design for the first times, mostly eyes closed except for a little bit of time when he opened them. Electrodes are at the parietal region, left and right, linked ear references, and of course a ground.

Does this look like the EEG of somebody who needs/would benefit from alpha/synchrony training? what I'm seeing is that my son (and husband too) are getting the " synchrony bell " to ring many many times. I wonder if this is what I should be training.

When last I assessed my son (in college now, 19 years old, diagnosed with ADHD, VERY obsessive, intellectualized, anxious, and ruminative, sleep onset problems all his life, and yes, medicating with Adderall (although not today at time of training), it was suggested by Pete that we train down the hot temporals -- never quite got the hang of NF at that time, however.

He seems much more amenable to training, now, however, and we have two months until he goes back to college. I'd like to do the best we can now. Any suggestions welcome. Oh I guess I could attach his ancient assessment, too.

Wow that's very interesting, but I have a few pendants, one rather newish, others I bought as very old used equipment, and as I said, when I used paste instead of saline the channel worked fine, so I do think my technique of attaching to the scalp is what I need to work on.

Liz,

When I first received my pendant I also had a similar problem with Ch 1. After speaking with Pete, I found out it may be a problem with some pocket pendants. I spoke with Bruce from Pocket Neurobics and he had it repaired within a week.

I think it was a solder joint issue.. Does Channel 2 seem to work ok? Are you getting a good signal from Ch2?

I thought I was going crazy when I encountered the problem, I thought I wasn't doing something right..
