Values in parentheses denote SE. HFO, mean high-frequency oscillation (>80 Hz) envelope amplitude. For frequency and log(HFO) × frequency, contrast is delta band.
-
↵* Significance at P < 0.01, which does not meet standard of significance for lower-level covariates;
-
↵† significance at P < 0.0001, which was defined a priori as the threshold for statistical significance for level 1 covariates.
