Partial correlation between instantaneous causality and phase-lag.

<p>Spearman's partial rank correlation coefficient between instantaneous causality and magnitude of phase-lag in the beta band between site pairs for monkeys GE and LU. The partialing is against the directional influences. All the results are significant at p<0.05.</p>*<p>denotes the channel pair that exhibits bidirectional interaction in the beta frequency band. The symbol “-” indicates that a value is not available.
