It would be helpful to have at least 19 channels so we can tie into the Neuroguide database to do normative comparisons of recorded EEG. Anyone figured this part out?
Can't you restrict, adjust or average what is taken from the database to allow a comparison to work with a different number of channels? If not, the database would seem inflexible for a commercial product.
There are a number of QEEG database products: Neuroguide, BrainDx, HBI, qEEG-Pro, etc., But they have all standardized on the 19 channel caps. This is because the clinics / practitioners using QEEG all have sufficient funds to afford the 19 or 24 channel amplifiers.
So, Marvin, if you are thinking of creating a new 19-lead EEG OpenBCI database, 19 leads cannot be done with current equipment, due to lack of proper time-lock synchrony between 2 boards not connected via daisy board, and I additionally was told when I asked a few years ago that there was no way to stack daisy boards to use more than one daisy per Cyton .
But I see no reason that you could not pull relevant features of larger sized brain regions from a 19-lead database and apply the results to interpretation of an 8-lead EEG of those regions.
