Overall pattern of directed connectivity results. Top − topographic representation of electrode pairs for which ANOVA yielded significant results. Brown − significant main effect of stimulus type; orange − significant main effect of group; violet − significant interaction between stimulus type and group. Bottom − connectivity index for DTF (y-axes) by frequency (x-axes). Vertical dotted lines − borders between frequency ranges (delta [δ] = 1–2 Hz, theta [θ] = 3–7 Hz, alpha [α] = 8–12 Hz, beta [β] = 13–30 Hz and gamma [γ] = 31–70 Hz). Rows − sources of connectivity; columns − sinks of connectivity. Typical readers (TR) − green, moderately dysfluent dyslexics (MDD) − blue, severely dysfluent dyslexics (SDD) − red. Words − solid lines, false font − dashed lines. Significant ANOVA results color coded as in the topoplot.
