Interaction effects correspond to a contrast of spatial (relevant > irrelevant) > temporal (irrelevant > relevant). A1, primary auditory cortex; MTG, middle temporal gyrus; PE, prediction error; Rel-Irrel, relevant-irrelevant; TF, time-frequency; TPJ, temporoparietal junction; V1, calcarine cortex.
