Measuring Connectivity in Linear Multivariate Processes: Definitions, Interpretation, and Practical Analysis
Figure 8
Frequency-domain measures of causality for the exemplary neurophysiological application (: left central EEG; : right central EEG; : parietal EEG; : occipital EEG). (a) Squared DC from to , plotted together with its corresponding threshold for significance . (b) Squared PDC from to , plotted together with its corresponding threshold for significance (). Vertical dashed lines in each off-diagonal plot denote the bounds of the beta frequency band (13–30 Hz).
