Direction of influence is from the electrode site at the left to the site at the top. Values of peak Granger causality are displayed together with the peak frequency in Hz. Values are only shown for spectra determined to be significant by the permutation procedure described in Methods. NS, not significant; —, the pairing of a site with itself, because the Granger causality is measured only between different sites.
