    Summary
    Intranasal OXT potentiated acoustic startle responses to negative stimuli
    1 context sentence
    Summary · context
    In two independent double-blind placebo-controlled experiments, each involving over 70 healthy male subjects, we investigated whether OXT affects modulation of startle reactivity by aversive social stimuli as well as subsequent memory for them.
