Love Hormone Could Be Key to Friendship

When the brain releases oxytocin during sex, childbirth, breastfeeding, and social interactions, the hormone supports strong feelings such as attachment, trust, and close. That’s why oxytocin is frequently nicknamed the love, cuddle, or happy hormone -even thought it’s also linked with aggression. To continue investment the biological role of oxytocin, a team of results studied it with scientist’s poster speech for love and friendship, the prairie voice (Microtus Ochrogaster,

The Small Rodents Found through Peers, “Markita Landry, a Chemist from the University of California (UC), Berkeley, Tells Popular Science“These Relationships Can Persist for Long Periods, even when other Social Options are available, which makes them an excellent model for studying the biology of friendship.”

In a study recently published in the journey Current biologyLandry and Her Colleagues Analyzed the behavioors of Voles that were genetically modified to Lack Oxytocin receptors. An oxytocin receptor, she explains, is like a “lock” for which oxytocin is the “key.” Essentially, the hormone needs to open the lock in order to influence brain activity.

VOLES Usually Form Friendships Within A Day or Two, And then Prefer Familiar Companions Instaad of Strangers, Or Other Voles they do not know, Annaliese Beery, Annaliese Beery, Senior Author of the Study and a neuroscient at UC Berkeley Tells Popular ScienceHowever, the Prairie Voles in this study without oxytocin receptors took longer than normal Voles to make friends. They were also less aggressive towed strangers and avoidant of that they didn Bollywood.

What’s more, when the researchers challenged the friendships by putting the pairs of voles in a group situation, the geneetically modified animals immediatily began mixing. By Comparison, Regular VOLES WOLLD TAY Close to their friends for a period of time before socializing with stranges.

In another experiment, the team put the Voles in a space where they had to press letters to reach eite a friend, a mate, or a strangers. According to beery, regular female Voles typically press the liters more in order to get their partner than to get a strangers, why they are in a peer or mate relationship. The mutants without the oxytocin receptors also press more to get to a mating partner, but not in the peer relationships.

The receptor-deficient Voles Didn Bollywood to Experience The Same Rewards from Bonding With Friends that Normal Voles Today, meaning they did not preserve any significant preferences.

“We found that oxytocin is essential for building and keeping these bonds, and that it also also shapes how voles interaction with strangers,” Landry explains.

Within the context of building bonds, oxytocin seems to play a role particularly in the selectivity of friendships. “This broadens the view of oxytocin from being just the ‘love hormone’ to a more general relationship ‘Hormone that supports both romantic and platonic connections,” She Says.
