There were no statistically significant main effects (all p > 0.15) in any of the ROIs for the Condition (infusion) term, except for a borderline effect in the left (p = 0.06) ventral striatum, reflecting a higher olfactory response under placebo. Condition also did not interact with Odor (all p > 0.50). Both findings suggest that the alcohol infusion did not (as with piriform cortex; see above) systematically alter the olfactory response in mesocorticolimbic reward areas.
