19 or more channels for Neuroguide QEEG ?

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.

    Bill, hi.

    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.
