[Eeglablist] Ground electrode location

[Andrew Hill]

No it probably won't matter.. but if it's a CMS/DRL setup of Ref / Ground then it may not be a true "ground".  What cap system?

Due to convenience reasons, we may be ordering some caps which have the ground electrode over a right hemisphere site. My understanding is that the location of the ground electrode on a conventional EEG system should not matter (in contrast to the location of the reference electrode, which does matter), but I wanted to be sure that putting it on the right hemisphere would not introduce any hemisphere asymmetries in the effects.
