Correlation between instantaneous causality and phase-lag.

<p>Spearman's rank correlation coefficient between instantaneous causality and magnitude of phase-lag in the beta band between site pairs for monkeys GE and LU. The results that did not meet significance at p<0.05 are included with their corresponding p-value.</p>*<p>denotes the channel pair that exhibits bidirectional interaction in the beta frequency band. The symbol “-” indicates that a value is not available.
