Effects of Intranasal Oxytocin on Functional Brain Network in Resting-state and Tasks

Effects of Intranasal Oxytocin on Male's Functional Brain Network in Resting-state and Tasks

To investigate whether and how intranasal oxytocin of 8IU treatment will alter the topology of functional brain network in resting-state and multiple tasks in healthy males.

In a randomized, double-blind, cross-over, placebo controlled design, healthy male volunteers receive intranasal oxytocin or placebo prior to functional magnetic resonance imaging.Subjects will then go through a decision making task, a emotion judgement task and an eight-minute resting-state scan in MRI scanner to investigate whether and how intranasal oxytocin alter the topology of functional brain network in resting-state and multiple tasks in healthy males. State anxiety and mood are measured before and after experiment as covariates to be controlled.

Inclusion Criteria:

• healthy subjects without past or current psychiatric or neurological disorders

Exclusion Criteria:

• with MRI Contraindications
