Need help to relate EEG data to different brain region


#1

I am currently working on CHB-MIT EEG database of epileptic patients to predict the seizure.
I need to relate the different channel signal to different brain region, but as the measurements are bipolar I cannot. Let’s say, the 12th channel data is collected from P7-O2 electrodes, not sure whether if I take this as a parietal signal or occipital signal?
Or, should I consider it as both?

Some EEG packages provide a re-reference function. You may be able to turn your bipolar data into single reference or other common montages.
