3.2 Neural entrainment at the sensor level Across the exposure period and averaged across all MEG channels, ITC values showed a highly significant interaction between frequency (tone versus triplet) and condition (structured versus random; F(1,69) = 7.05, p = 0.010, ŋ p 2 = 0.09).
Follow-up tests of individual clusters revealed another significant correlation in the right temporo-frontal cluster (r(22) = 0.53, p FDR = 0.014; cluster 1), while the left temporal cluster showed a marginally significant relationship with the rating score (r(22) = 0.39, p FDR = 0.079; cluster 2) and the right superior parietal cluster had no predictive value (r(22) = 0.24, p FDR = 0.260; cluster 4). 4 Discussion The present study showed that participants were able to learn nonlinguistic statistical regularities simply through exposure to the stimulus stream, in the absence of explicit instructions to detect the patterns.
