NCT03577457

Brief Summary

The primary objective of this study is to identify any interaction between oxytocin and serotonin on neural and behavioral activity related to social reward and decision making by a double-blind, placebo-controlled, between-subject, pharmacological fMRI design

Outcome Measures

Primary Outcomes (2)

  • Changes in brain neural activity during the social reward processing as assessed via fMRI

    Whole brain and region of interest (ROI) regression analysis will be used to compare the neural activity of participants in response to social reward task in different treatment groups.

    approximately 45 minutes after intranasal administration of oxytocin, or placebo, approximately 5.5h after administration of ATD, or placebo

  • Changes in the resting state as assessed via fMRI

    Resting state activity in the social reward related and decision making brain networks will be compared between the treatment groups

    Time Frame: approximately 45 minutes after intranasal administration of oxytocin, or placebo, approximately 5.5h after administration of ATD, or placebo

Secondary Outcomes (3)

  • Associations with Personalities of subjects

    before 30mins ATD or placebo administration

  • Behavioral performance in decision making task

    approximately 4h after administration of ATD, or placebo, before nasal spray

  • Behavioral performance in social reward related task

    approximately 105 minutes after intranasal administration of oxytocin, or placebo, approximately 6.5h after administration of ATD, or placebo
