NCT02737436

Brief Summary

The investigators plan to conduct functional MRI scanning with a group of mothers who are blindly and randomly assigned either intranasal oxytocin or a placebo. The purpose of this investigation is to explore how oxytocin may modify early maternal brain and behavioral responses to infant cues. This study will examine, for the first time, a potential pharmacological intervention for maternal neglect which targets core neurobiological deficits. This may eventually be used to supplement and augment other psychosocial and behavioral interventions. In addition, the investigators will examine sex differences in parental brain and behavioral responses to oxytocin by also recruiting fathers to participate in a similar protocol.

Outcome Measures

Primary Outcomes (1)

  • Differences in Brain Activation (Blood Oxygen Level Dependent [BOLD] Signal) of Dopamine Reward Regions and Prefrontal Cortex After Intranasal Oxytocin Administration in Mothers

    We will compare the BOLD signal of regions in the brain (including the ventral striatum, caudate, putamen, amygdala, and the medial prefrontal cortex) in mothers who receive intranasal oxytocin, compared to placebo. In every analysis, we measure the difference in brain response (BOLD signal) between viewing the mother's own infant (O) more than unknown infant (U) faces (O\>U), during fMRI scanning.

Study Arms (2)

Oxytocin

EXPERIMENTAL

Intranasal oxytocin (24IU) given 50 minutes prior to behavior assessment or scanning

Drug: Intranasal OxytocinProcedure: Functional MRI scanning

Placebo

EXPERIMENTAL

Intranasal placebo spray given 50 minutes prior to behavior assessment or scanning

Drug: PlaceboProcedure: Functional MRI scanning

Interventions

Intranasal oxytocin (24IU) given 50 minutes prior to behavior assessment or scanning

Also known as: Syntocinon
Oxytocin

Intranasal placebo spray given 50 minutes prior to behavior assessment or scanning

Placebo

All study participants underwent two functional MRI scanning visits. On one occasion this was after receiving an intranasal dose of oxytocin; on the other occasions, after receiving intranasal placebo dose.
