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.
