Results of the GLM analysis. The temporal dynamics of normalized beta in the STS and IFG. (A) AV Incongruence showed a significant effect in the STS before auditory onset, at the same time that the encoding of visual feature is significant. (B, C) The effect of AV asynchrony in the IFG was significant around − 50 ms until a fused percept is identified in the STS but last until 200 ms post-auditory stimulus onset when the AV inputs cannot be fused (i.e. in combination condition). (C, D) Combination was associated with a significant effect in the IFG at ~ 700 ms, after repeated incongruence X combination interaction effects at several time points in the STS. In contrast, fusion effects were significant only around the time of audio onset. Thick horizontal lines and light grey areas indicate time windows where parameter estimates diverge significantly from zero at a temporal cluster-wise corrected P-value of 0.05. The shaded error bounds indicate SD. STS superior temporal sulcus, IFG inferior frontal gyrus. Image made using Microsoft PowerPoint, version 16.41, and Matlab 2019b.
