In a pharmacology experiment, 26 participants received either a selective 55-HT2A\text{HT}_{2A} receptor agonist at a subhallucinogenic dose or placebo before completing a cognitive reappraisal task during fMRI. The agonist increased functional coupling between medial prefrontal cortex (mPFC) and amygdala during reappraisal trials and was associated with greater reduction in negative affect ratings. Which outcome is most consistent with the observed neurotransmitter effects?
