You may have heard of the "love hormone," or oxytocin. But you may not know that scientists have relied on cuddly rodents like the prairie vole to help us understand how this protein works in our brains.
Voles are stocky, mouse-like little mammals that range over most of North America. One species in particular, the prairie vole, is known for its fidelity: Prairie voles pair-bond and mate for life.
And so, for years, scientists have known that oxytocin is important in facilitating the feeling of love in both humans and voles. However, a new
study suggests love can prevail even without the "love hormone" – at least among prairie voles.
On today's episode, NPR's science correspondent
Jon Hamilton tells Short Wave co-host
Emily Kwong how prairie voles, once again, are helping us understand and appreciate something as abstract as love.
