LFP-LFP phase synchrony was computed from the phase of the complex wavelet transform, using the pairwise phase consistency (PPC). PPC is a measure of how consistent across trials the relative phase angles between two signals are, independent of their absolute phase. It is an unbiased estimator of the square of the mean vector resultant length (Kornblith et al., 2015; Vinck et al., 2010). Presented results represent averages across all electrode pairs between hemispheres (Figures 7A–7C), all electrode pairs within the hemisphere contralateral to the sample hemifield (the ‘‘sender’’ on swap trials; Figures 7D, 7F, and 7H), and all electrode pairs within the hemisphere ipsilateral to the sample hemifield (‘‘receiver’’ on swap trials: Figures 7E, 7G, and 7I) within each session. These values were then averaged across all sessions.
