If hormones and neurotransmitters are important for romantic emotions, maybe drugs could be created that would promote or inhibit the feeling of love. Would it be possible to create a “Love Potion Number 9”, like the song suggests? Is chocolate possibly a food that stimulates romance by tweaking our brain chemicals? Do you think it would be possible to invent a drug to help people get over a break up? Which chemicals would be affected in these situations? Finally, would it be right to stimulate or inhibit relationships by intervening with chemicals?

Harry Harlow’s research showed that monkeys who were deprived of a maternal presence were distressed and socially impaired. He didn’t look at the neurobiology though given that his classic studies were done in the early 1960s. Speculate on what you think might have occurred in Harlow’s monkeys in regard to oxytocin and vasopressin. How long lasting would these effects be? Is it possible that the effects could transfer to future generations? Finish by addressing how understanding this brain chemistry might be helpful to assist children who grow up in abusive or neglectful homes.
