Abstract: Vasopressin and the scent of social interaction Peptide hormones, like oxytocin or vasopressin, are well known to influence social behaviour in various mammalian species. While oxytocin is thought to be prosocial and enhance cooperation, vasopressin may function to trigger aggressive behavioural responses. In most mammals, the olfactory system is key to social recognition, and now a population of vasopressin-expressing interneurons in the olfactory bulb has been identified as being required for proper social recognition in rodents. The activity of these neurons, in response to vasopressin signalling, is linked directly to the modulation of information processing by the olfactory system. Although vasopressin itself may not play an identical role in humans, such an experience-dependent mechanism of hormone release underlying social recognition may be common.
