Question regarding electrodes #13

Hi,

I have a question regarding the electrodes. In your readme, it says: “The voltage difference oscillations between the 2nd and 3rd electrodes are the target alpha waves, which is then fed to the circuit to be amplified and filtered.” I was wondering why this is, is it not possible to only measure the waves from O2? Or is there a specific reason (e.g. more accurate data) to take the difference between the O2 and Fp2 electrodes?

Thanks in advance!

Olivier

Perhaps it's a result of Einthoven's triangle?
