Which is the anatomically most sensible 9-sets grouping for 64 electrodes, applied using a biosemi 64(+2)-holes?
The sets would be:
Anterior left
Anterior right
Anterior central
Medial left
Medial right
Medial central
Posterior left
Posterior right
Posterior central
(in particular, I am wondering about Fp1, Fp2, F1 and F2, with respect to the central / left-right groupings)
