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.</div>

<p class="MsoNormal">Hi, </p>
<p class="MsoNormal">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 ?</p>
