Hi Nick,

Cross-coherence and ITC both relate to the consistency of phase angle  
from trial to trial at each time point and frequency. The only  
difference is that ITC represents the consistency of the phase angle  
FOR A SINGLE SIGNAL across trials for each time point and frequency,  
while channel or IC cross-coherence represents the consistency of the  
phase angle DIFFERENCE BETWEEN TWO SIGNALS across trials for each time  
point and frequency.
