The only suprathreshold result to arise from the analysis in this smaller sample (measured either voxel-wise or in the NAc ROIs) was a potentiation of the posterior cingulate/retrosplenial region under alcohol for both the [AO > NApO] ([−2, −40, 28], 153 voxels at p < 0.001) and [AO > ApCO] ([6, −34, −26], 5 voxels at p = 0.001) differences images (Fig. 6). That is, the AO response (relative to either of the control odor classes) was greater during alcohol infusion than during placebo infusion.
