Prolonged alteration of 1/f slope with stimulus saliency. (a) Average smoothed pre-, post-early, and post-late power spectra for standard and oddball trials within the constrained frequency range (20–45 Hz) show different high: low frequency balances between trials. (b) Both standard and oddball responses show significant flattening of the aperiodic estimate early after stimulus playback, but this change is only maintained into the late post-stimulus time window for salient oddball trials.
