Hi,<br>
<br>
I'm interested to know what EEG systems you're running. We have 64 channel BioSemi Active 2 and Brain Vision actiCHamp systems and are wondering if we can use the same gel with both.<br>
<br>
Thanks,<br>
.. Frank<br>

Hi Pamela,<br>
<br>
Most of the gels I have used also have [small] bubbles in them, and as<br>
far as I know it hasn't affected the recording quality; they get<br>
rubbed out anyway when I apply the gel and rub it around, abrade the<br>
skin, etc.<br>
<br>
In my experience, I can get the gel I use to be less bubbly if I stir<br>
it vigorously, although I'm not sure if it really matters.<br>
<br>
I've generally had good luck with SuperVisc high viscosity gel<br>
recently (<a href="http://www.brainproducts.com/files/public/products/brochures_material/pr_articles/0801_SuperVisc_FM.pdf" rel="noreferrer" target="_blank">http://www.brainproducts.com/files/public/products/brochures_material/pr_articles/0801_SuperVisc_FM.pdf</a>),<br>
and with similar gels in the past (although I don't have the exact<br>
names on hand; I think the manufacturer was ElectroCap).<br>
<br>
Best,<br>
Steve<br>
