frequency bands (theta, alpha1, alpha2, beta1, beta2, gamma1, gamma2), the magnitude of its contribution can be visualized within a matrix where its position denotes the electrode pair (i.e., the row and column labels correspond to the electrode pair), with separate matrices for each band. Each element of the component vector has been converted to a z-score and only elements with | z | > 1.96 are displayed, where green shows pairs with | z | < 1.96, red shows higher coherence in NSAC vs. LTAA, and blue shows lower coherence in NSAC vs. LTAA. Examination of these maps showed higher theta coherence between midline (Cz, FCz, Fz, CPz) and mostly left ipsilateral electrodes (Fp1, PO5, PO7, CB1, O1, AF3, PO3, FC2, CP2, AF4) and lower coherence between most electrodes with Fp2, F6, and T8 (see Fig. 2) in NSAC vs. LTAA. Fig. 2 also shows lower alpha1 coherence between most electrodes with CPz and Fp2 with some lower coherence also between left frontal/parietal regions (Fp1 with PO7 and PO5), and a similar but more extensive pattern of lower alpha2 coherence in NSAC vs. LTAA. There are scattered examples of both higher and lower beta1 coherence (see Fig. 3), but a
