Additional animal research shows that oxytocin may relieve stress and anxiety in social settings and may be more rewarding than cocaine to new mothers.
But it's the notion that oxytocin influences feelings of well-being and sensitivity that will have advertisers and marketers most interested - imagine advertising campaigns tailored to hormones. At Neuroscience 2010, the Society for Neuroscience's annual meeting, details were revealed about the latest oxytocin research.
- Paul Zak, abstract 387.18, says oxytocin is linked to happiness and well-being. When trusted with money from a stranger, women who showed the greatest increase in oxytocin also reported being more satisfied with their lives, resilient to adverse events, and less likely to be depressed.
- Paul Zak, abstract 387.21, says oxytocin increases sensitivity to advertising. Researchers found that after sniffing oxytocin, people were more empathetic toward public service announcements and more likely to donate to their causes.
- Martha Caffrey, abstract 888.22, says in the presence of their newborns, rat mothers' brains did not respond to learned cues associated with addictive drugs. This suggests that maternal bonds — a function of oxytocin — profoundly influence brain activity and behavior, with important implications for drug-addicted mothers.
- Jason Yee, abstract 190.7, says oxytocin reduces anxiety in stressed animals, but only if they recover in the presence of a friend. It is less effective at relieving stress for isolated animals, suggesting that social contact is an important factor in its ability to reduce anxiety.
- Larry Young says that oxytocin is important in evaluating social signals and may be as rewarding as drugs of abuse in some monogamous animals. The findings have important implications for designing novel treatments for several psychiatric disorders that affect social interactions, including autism spectrum disorders and schizophrenia .
"Converging evidence from different research studies indicates oxytocin and other hormones have a profound influence on value judgments, shaping emotions and behaviors in humans and other animals," said press conference moderator Margaret M. McCarthy, PhD, from the University of Maryland School of Medicine.
