Based on visual inspection of the TFRs at the MESOIs, five TFROIs (δ1, δ2, θ1, θ2 and α), as defined in Table 2 and shown in Figure 1b. were selected for EROEVK computation. Topographical maps of which shown in Figure 1b. δ1 and δ2 EROEVK power have a midline-symmetrical, parietal localization, with δ2 EROEVK power having a more widespread distribution with a slightly more anterior (centro-parietal) peak. The θ1 and θ2 EROEVK power is more anterior than the δ EROEVK power, with a fronto-central peak. θ2 EROEVK power also shows a bilateral peak over the left and right parieto-occipital regions. α EROEVK power has a bilateral distribution over left and right occipital regions.
