Frans--Are you familiar with the International 10-20 system of
electrode placement? That is, do you know what we're talking about
when we refer to Cz, O1, O2, F3, F4, T3, T4, Pz, etc.? If you can't
find a local reference, I could scan in an EEG site map of the head
so you could locate each of the standard electrode sites.
Actually, this is something that probably belongs on our website.
