  1. 01HumanRandomized controlled trialEfficacy outcome

    In human subjects, intranasal oxytocin prevented the fall in trusting behavior after repeated breaches of trust that occurred with placebo.

    In plain wordsIn people who learned their trust was breached, those given oxytocin kept trusting; those given placebo trusted less.

    Summary
    We find that subjects in the oxytocin group show no change in their trusting behavior after they learned that their trust had been breached several times while subjects receiving placebo decrease their trust.

    Summary · context
    We examined the neural circuitry of trusting behavior by combining the intranasal, double-blind, administration of oxytocin with fMRI.
  2. 02HumanRandomized controlled trialMechanism

    In human subjects, intranasal oxytocin was associated with reduced amygdala activation during adaptation to breach of trust compared with placebo.

    In plain wordsIn people given oxytocin, brain scans showed less activity in the amygdala than in people given placebo when trust was breached.

    Summary
    This difference in trust adaptation is associated with a specific reduction in activation in the amygdala, the midbrain regions, and the dorsal striatum in subjects receiving oxytocin, suggesting that neural systems mediating fear processing (amygdala and midbrain regions) and behavioral adaptations…
