Decoding in the Left Superior Temporal Sulcus (STS) (left panels) and the Inferior Frontal Gyrus (IFG) (right panels). (A) Time course of univariate classification (accuracy) for ‘abga’, ‘agba’, ‘apka’ and ‘akpa’ responses from combination vs. ‘ada’ and ‘ata’ responses from congruent. Univariate classification between the responses of interest from congruent and combination conditions was possible in the IFG at ~ 360 ms and in the STS at ~ 380 ms. (B) Time course of univariate classification (accuracy) for ‘abga’, ‘agba’, ‘apka’ and ‘akpa’ responses from combination vs. ‘ada’ and ‘ata’ responses from fusion. Univariate classification of responses of interest from fusion and combination conditions was possible in the STS at ~ 170 ms, ~ 340 ms, ~ 600 ms and ~ 700 ms, but not in the IFG. (C) Time course of univariate classification (accuracy) for ‘ada and ‘ata’ responses from congruent vs. ‘ada’ and ‘ata’ responses from fusion. Univariate classification of responses of interest from fusion and combination conditions was possible in the STS at ~ − 100 ms, ~ 170 ms and ~ 650 ms, but not in the IFG.
