Effect of ROI size and localization on ECG-EVM pulse rate coherence. (A) Reference monkey face on which is superimposed ECG-EVM coherence maximum power based on a 10 × 10 pixel matrix covering the entire face (B) or smaller pixels covering the eyes and muzzle (C). Note that B and C share the same color scale.
