Twin identification success rates for different FC or EC measures in individual frequency bands: Amplitude Envelope Correlation without (AEC) and with correction (AEC-c), directed Phase Transfer Entropy (dPTE) and Phase Lag Index (PLI).

The success rate based on the original data, as well as after removal of the common pattern across subjects (using SVD), are given. The asterisks represent the significant values after permutation testing: p-value ≤ 0.05(*), p-value ≤ 0.01(**) and p-value ≤ 0.001(***).
