Figure 5. ROI results of the second fMRI sample.

(a) ROI analysis of the parameter estimates of the left and the right AIC under the four experimental conditions. Raincloud plots were used for visualization. (b) Correlation between the interaction effect of bilateral AIC and relative interoceptive accuracy. The values of the variable in b were normalized as z-scores.

Figure 5—figure supplement 2. Activation maps without and with RETROICOR +RVHRCOR correction for the second fMRI sample.

Figure 5—figure supplement 2.

(a) Main effect of interoceptive vs. exteroceptive attention (BDT vs. DDT). (b) Main effect of breath curve feedback condition (delayed vs. non-delayed). (c) Interaction between attention type and breath-curve feedback condition ([delayed – non-delayed] BDT – [delayed – non-delayed] DDT). Pink purple contours indicate corresponding activation in the first sample. We used an extremely liberal threshold of voxelwise p<0.05 for visualization.

The difference of the signals of the AIC between the analyses with and without physiological corrections was only evident under the main effect of interoceptive vs. exteroceptive attention (BDT vs. DDT), but not under the interaction contrast, confirming that the interaction effect of the AIC was not significantly impacted by the physiological noises.
