    The present study employed a novel computational framework to investigate these latter aspects in 15 oxytocin-sensitive regions using data from randomized placebo-controlled between-subject resting state functional MRI studies incorporating 200 healthy subjects.
  2. 02HumanRandomized controlled trialMechanism

    In healthy subjects, oxytocin modulated effective connectivity among 15 brain regions (54 links), mainly by increasing it within and between emotion, reward, salience, attention and social cognition networks.

    In plain wordsIn healthy people, oxytocin changed how brain regions influence each other, mostly by increasing connectivity between networks for emotion, reward and social thinking.

    Summary · context
    The effects of oxytocin were primarily characterized by increased effective connectivity both between and within emotion, reward, salience, attention and social cognition processing networks and their interactions with the default mode network.
