Bold font indicates the maximally activated voxel in the cluster. Italics indicate that a peak falls under the same cluster as the preceding peak; T-map thresholded at P_uncorrected = 0.005.

^aCluster is also significant if masked exclusively by DETECT T− minus PASSIVE T−(attention to taste).

^bCluster is also significant if masked inclusively by PASSIVE O+ minus PASSIVE O−(sensory olfactory stimulation).

^cSignificant at P_FDRcorrected = 0.05 across the whole brain.

^dSignificant at P_FDRcorrected = 0.05 across the region of interest.

^eNot significant corrected for multiple comparisons, but we chose to report this peak because it contributes to the peak in the conjuction analysis.
