Unlike a coherence analysis used for revealing cooperating parts in the brain, causality measures make possible not only to evaluate the strength of relations but also a direction of their influence. Well-accepted Granger causality and other derived causality measures based on multivariate autoregressive models have been used to analyse directions of information flow in multichannel time series in econometrics and neurophysiology for a long time. Recently, a new method Phase Slope Index (PSI) based on completely different approach has been proposed. This paper compares conditional Granger causality with PSI, shows some important issues with PSI and proposes an idea how to interpret results of both methods used on the same data set."@en . .
