  1. 01HumanRandomized controlled trialMechanism

    In children with autism, a 4-week course of intranasal oxytocin significantly reduced intrinsic amygdala-orbitofrontal connectivity, particularly at the 4-week follow-up.

    In plain wordsIn children with autism, 4 weeks of nasal oxytocin reduced connectivity between the amygdala and orbitofrontal brain regions, most clearly at follow-up.

    Fifty-seven children with autism aged 8-12 years (45 boys, 12 girls) participated in a double-blind, randomized pharmaco-neuroimaging trial involving twice-daily administrations of intranasal oxytocin or placebo.
  2. 02HumanRandomized controlled trialMechanism

    In children with autism given intranasal oxytocin, reductions in amygdala-orbitofrontal connectivity were correlated with improved social symptoms.

  4. 04HumanRandomized controlled trialMechanism

    In children with autism, the neural and cardiac autonomic effects of oxytocin were modulated by epigenetic modifications of the oxytocin receptor gene, and were more pronounced with reduced methylation.

    In plain wordsIn children with autism, oxytocin effects on the brain and heart were stronger in children with lower oxytocin receptor gene methylation.
