Kerstin Uvnas Moberg, a Swedish scientist, was the first person to understand that oxytocin isn't just for childbirth. She learned that it's also central to the action of the parasympathetic nervous system, which she calls the "calm and connection system."

In 2003, she wrote "Oxytocin Factor," explaining all this.

The Life Science Foundation has an excellent interview with her. In it, Moberg points to studies showing that real eye contact between nothers and babies has been reduced by half. She also discusses the drive to produce oxytocin-based drugs. Like me, she believes it's better to learn to activate your oxytocin system behaviorally.
