Happy belated 'Sweetest Day'
The Meadow Vole is promiscuous while its cousin the oxytocin rich Prairie Vole is monogamous and will stay with its mate for life.
USA Today has reported:
By transferring a single gene to the pleasure center of the naturally promiscuous male vole, researchers at Yerkes National Primate Research Center at Emory University in Atlanta were able to make it happily monogamous, they say in a letter in the journal Nature.
In studying the brain chemistry of the two mammals, researchers found that when the monogamous prairie vole mates, the pleasure hormone dopamine is released in its brain. The receptors for that dopamine are located in the brain's pleasure center, which also happens to be where the receptors for the hormone vasopressin are located. And vasopressin is linked to social learning.
