separate CMS/DRL lead or in bundle with other electrodes

[carjun]

Hi Coen,

I have only experience with infant testing (with small heads, so electrodes very close to each other), and most of the previous labs I worked in used biosemi, always with a separate CMS/DRL lead. In our current lab we have CMS/DRL integrated in the bundle. Now we often experience bridging with central electrodes (flat channels), much more frequent than I recall from the other labs. I understand that this has to do with too much gelling around CMS (and that infant heads are not yet at perfectly-shaped - with the back of the heads being rather flat). Yet I could not help wondering whether the cms/drl is separate or not might also be a factor that affects the data recordings, particularly because it is now virtually impossible to guide the CMS/DRL cables around the other cables. What do you think?
Best wishes Caroline

Whether the cms/drl is separate or not is absolutely unrelated to gel bridges.
