35 – Phase Difference of Coherence<br />
Defined as the average Phase difference of the time series of<br />
instantaneous coherence between any pair of electrodes with respect to a<br />
common electrode. For example, the two time series of instantaneous<br />
coherence between Cz-P3 <strong>and</strong> Cz-P4 are the input to the phase analysis in<br />
which the average phase difference between the two time series of coherence
