Accordingly, excluding area RL from the analysis revealed a decreasing trend in the trial-to-trial variability along the hierarchy in the high-frequency state ( S H : Pearson’s r with anatomical hierarchy score = -0.94, p = 0.02; S I : Pearson’s r = -0.43, p = 0.5, S L : Pearson’s r = -0.46, p = 0.4).
