Functional connectivity maps of frequency-specific increases in amplitude envelope correlations in mTBI compared to controls, for the delta (1–4 Hz; top), theta (4–7 Hz; middle) and alpha (8–14 Hz; bottom) frequency bands. All images derived from the NBS-Extent method (p < 0.05, corrected). Additionally, adjacency matrices of p values for contrasts of intra- and inter-hemispheric lobe-by-lobe connectivity measures for mTBI versus control are shown to the right in each panel; grey-to- white indicates significant interactions for mTBI > Controls (Bonferroni-corrected at p < 0.05), black indicates no significant difference (p > 0.05, corrected).
