“…Left posterior alpha power also increased in the Active group ( t = 2.16, P = 0.045), which, however, failed to survive the double contrast ( t = 1.36, P = 0.184). As evinced by recent neural computational and electrophysiological (including intracranial recordings) studies, alpha projections track a selective P→F direction (i.e., directed alpha P→F connectivity) via P→F cortical synchronization or traveling waves ( 15 , 21 , 22 , 32 36 ). We thus used Granger causality (GC) analysis to examine changes in this alpha connectivity.…”

“…As evinced by recent neural computational and electrophysiological (including intracranial recordings) studies, Right Posterior Power (a.u.) alpha projections track a selective P!F direction (i.e., directed alpha P!F connectivity) via P!F cortical synchronization or traveling waves (15,21,22,(32)(33)(34)(35)(36). We thus used Granger causality (GC) analysis to examine changes in this alpha connectivity.…”

“…An information theory metric, phase transfer entropy (PTE), was used to estimate the direction of information transfer in the 4-5 Hz frequency range 19,67 . PTE quantifies the mutual information between the past of signal ‘X’, X(t- τ ) and the present of signal ‘Y’, Y(t).…”

“…It is known that the local synchrony pattern varies remarkably across the cortex [ 12 ], and it has been reported that this regional variation is associated with the hierarchical organization of information processing during human functioning [ 13 ]. A direct measure of neural synchrony is spectral power, which measures the activity of the spatial sum of the cortical responses in a local assembly [ 14 , 15 , 16 ]. Previous studies have linked episodes of MW to oscillations at particular frequencies of neuronal activity in the brain.…”
