[Eeglablist] Coherence or Correlation among set of electrodes

[Gregory Perry]

Even the most recent generation EEG acquisition hardware leaves a lot to be desired in terms of correlating areas within the brain that are interrelated.  This doesn't seem like a hard problem to solve with active electrodes placed at each 10/20 region, if they all shared a high resolution time base.  Think reverse GPS, by measuring timing variances between each electrode site (and especially at EEG spectrum frequencies), there is no reason why specific physical regions in the brain could not be triangulated for analysis.  For extra credit, cortical folding patterns could be integrated with the acquired data to derive subject-specific brainwave signatures.

Current EEG analysis methods are stuck in a 2D world unfortunately.

Hi,
Just wonder if there is a way to calculate the coherence measure between two regions( set of channels—instead of two single channels) in EEGLAB or any other software?  In other word, how can we find regions in the brain which their activities are mostley related to each other using EEG ?

Best,
Iman
