Guest guest Posted March 18, 2006 Report Share Posted March 18, 2006 Tamson, To use a common reference (Iboth actives referenced to one, as in F3/Cz/g/F4/Cz, just use a jumper between the two references and plug the single Cz electrode into either end of the jumper. BTW, given the recent experience of several group members, I'd seriously consider using F3/A1/g/F4/A2 and link the references. That way you should get the same effect (comparing both sites against the same reference) without the potential for getting undesired side-effects from training over the cingulate.

Guest guest Posted March 18, 2006 Report Share Posted March 18, 2006 Thanks. I didn’t even think about the jumper…my next best guess would have been to get them as close together as possible.

Guest guest Posted March 19, 2006 Report Share Posted March 19, 2006 Yes, particularly if you are using the PET which doesn't allow for using a jumper.
