Several years later, Tom Insel, a former colleague of Carter's who is now president of the National Institute of Mental Health, began a comparative study analyzing the
brains of prairie voles and their less monogamous cousins, the montane voles.
PAIR - BOND Just 24 hours in each other's company without mating can be enough to bond a
pair of prairie voles for life.
Although scientists have observed the behavioral and chemical
side of prairie vole love, the neural networks behind commitment are still a mystery.
Load up on adrenaline, or cool down with oxytocin About 20 years ago, neuroendocrinologist Sue Carter began examining the
brains of prairie voles to understand why the small rodent indigenous to the midwestern plains of the United States is one of the natural world's great romantics.
Scientists could predict how quickly a
pair of prairie voles would start getting close to each other and suggest the study could have applications for human bonding.
The architecture suggested that behaviors associated with oxytocin release would feel good in the brains
of the prairie voles but leave the montane voles relatively unaffected.
Previous research indicates oxytocin — a hormone that promotes social and maternal bonding — acts in the anterior cingulate cortex (ACC)
of the prairie vole brain to encourage consoling behavior.
