Modulatory effects related to Asal. A: Brain regions where the BOLD signal co‐varied positively with the Asal index. Significant effects were found in the STC bilaterally. The signal plots show the parameter estimates associated with the effect of Asal, separately for left and right sounds (aL/aR) and congruent/incongruent AV conditions. The plots show a larger effect of Asal for left than right sounds, but this was not statistically significant. B: In the PPC, we found an interaction between Asal and AV spatial alignment. The BOLD signal increased with increasing auditory salience when visual and AEs occurred on the same side of space (i.e., congruent trials, positive parameter estimates in the signal plots), but decreased when visual and AEs occurred on opposite sides (incongruent trials, negative parameter estimates). rCon/uCon: spatially congruent related/unrelated AV events; Inc: spatially incongruent AV events. Activations are projected on the standard MNI template. Effect sizes are plotted in arbitrary units (a.u.); error bars are 90% confidence intervals.
