So, this study is suggesting that oxytocin, the love and bonding neurotransmitter, may play a bigger role in other activities than previously thought. This makes a lot of sense intuitively - of course, if you are in a state of liking, bonding, attraction, inhibition-reduction, and novelty-seeking, you are more likely to be creative, or be able to quickly adopt new ideas or new ways of thinking.

"Using double-blind placebo-controlled between-subjects designs, Studies 3–6 (N = 191) finally showed that intranasal oxytocin (vs matching placebo) reduced analytical reasoning, and increased holistic processing, divergent thinking and creative performance. We conclude that the oxytonergic circuitry sustains and enables the day-to-day creativity humans need for survival and prosperity and discuss implications. "
