Oxytocin nose-drop brings marmoset partners closer

Researchers from the University of Nebraska at Omaha, show for the first time that common marmosets—Callithrix jacchus, a species of New World monkey—that receive oxytocin in nose-drops attract more social interaction from their mates. Oxytocin is a hormone released naturally in the blood and brains of humans and other mammals, during social and sexual behaviors. Previous studies showed that individuals who receive an oxytocin boost show greater sociability, through increased cooperation, altruism and communication with members of the same social group. However, much less is known about how others interact with those treated with oxytocin.
