Hello,

I was wondering what the best location for the reference electrode is. I found some works where the authors used mastoids... what about earlobes? Can you please suggest some papers to support an eventual choice.

Thanks
Alessandro

Alessandro,
Both earlobes and mastoids work fine. Earlobes tend to be a little simpler to setup, since it just requires a clip electrode, but if you have a cap with mastoid electrodes, that will be fine as well.
