Effects of Intranasal Oxytocin on Striatal Functional Connectivity

Effects of Intranasal Oxytocin on Striatal Functional Connectivity in Healthy Males

To investigate whether 40 IU of intranasal oxytocin treatment can influence the resting-state functional connectivity in healthy males.

In a double-blind, between-subject, placebo controlled design, investigators plan to investigate the effects of oxytocin treatment on resting-state functional connectivity.

Subject will receive either intranasal oxytocin or placebo administration and go through a seven-minute resting-state scan in MRI scanner to test whether oxytocin changes functional connectivity in the brain. Trait anxiety and mood questionnaires will be administered as control variables.

Inclusion Criteria:

• healthy subjects without past or current psychiatric or neurological disorders

Exclusion Criteria:

• with MRI Contraindications
