Subjects passively listened to two sequences of 12 acoustic tones. a left: exemplary sections of low and high regularity sequences arranged by their frequency. Grey lines indicate triplets. Right: transition matrices of subsequent tones for both sequences. b top: cortical distribution of evoked activity 50–70 ms post onset of each of the three tones in a triplet. Bottom: source-reconstructed evoked activity in bilateral temporal cortices (bottom right inset) across triplets in the low and high regularity condition. Shaded areas indicate the standard error of the mean (SEM).
