Two-way repeated measures ANOVA with PLI as dependent variable revealed a significant main effect of Tone in the delta, theta and alpha/beta frequency bands (0–50 ms, 50–350 ms and 350–800 ms time windows) in the frontal and parietal cortices, when collapsing across B6 and D2 groups (Supplementary table 1). Post hoc pairwise comparisons showed larger PLI in response to noise tones (vs. standard and/or rare tones) during the 0–50 ms, 50–350 ms and 350–800 ms time windows in the frontal and parietal delta, theta and alpha/beta bands. Larger PLI was also observed in response to rare tones (vs. standard tones) (Supplementary table 1).
