Mean log power and its relationship to model prediction error.

Upper plots show MLP for the same two subjects in previous figures. MLP is normalized over the frequency range by subtracting a linear ramp as a function of frequency, so that event-related changes are emphasized rather than the 1/f power gradient. Conventions are otherwise the same as Fig 3. Lower plots show the time by frequency matrix of correlations between past MLP and prediction error. The real part of the trial-wise error vector (plots one and two) was generally correlated positively with the trial-wise past MLP. The PLV_error (plot three) was generally positively correlated with subject-wise past MLP.
