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 more spatially distinct pattern of higher beta2 coherence on the left involving F7, CP5, F5, P5, PO7, F3, P3, CB1, O1, AF3, FT7, and T7 in NSAC vs. LTAA. As seen in Fig. 3, the coherence matrices for gamma1 and gamma2 are nearly identical, and show higher gamma coherency in NSAC vs. LTAA among left ipsilateral electrodes (including FT7, TP7, F7, FC5, CP5, F5, P5, PO7, F3, P3, CB1, O1, AF3, FPz, and Fz) and P8 with most electrodes, with some lower coherency between PO4 and mostly ipsilateral electrodes. Overall, the matrices shown in Fig. 2, Fig. 3 give the impression of mostly higher theta and alpha coherence in LTAA compared to NSAC, and lower gamma coherence in LTAA compared to NSAC.
