Different levels of a receptor for a hormone involved in social bonding may explain individual variation in offering comfort during stressful situations. Like humans, animals console each other in times of distress: monkeys hug and kiss, and prairie voles groom each other.
James Burkett, PhD
Emory postdoc James Burkett described his research on voles at a press conference on “The Neuroscience of Emotion and Social Behavior” at the Society for Neuroscience meeting in San Diego on Sunday. Here are Video (Burkett’s part is roughly from 4:50 to 9:00) and the scientific abstract.
Burkett’s presentation, on oxytocin-dependent comforting behavior in prairie voles, outlined an extension of his graduate work with Larry Young at Yerkes National Primate Research Center, which was published in Science in January 2016 and impressed oxytocin skeptic Ed Yong. Burkett, now in Gary Miller’s laboratory at Rollins School of Public Health, also masterminded a Reddit “Ask me anything” in February.
The rest of the Society for Neuroscience press release:
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. In humans, the ACC activates when people see others in pain. Some degree of personal distress motivates comforting behaviors, but too much actually makes animals (including humans, chimpanzees, and rats) less likely to offer comfort.

White-striped birds tend to be http://www.magliettedacalcioit.com more aggressive and less parental than the tan-striped birds, you will learn. Hey, that sounds sort of like prairie voles and meadow voles.
