Human social behavior and oxytocin: Molecular and neuronal mechanisms

Oxytocin (OT) is a hormone that is crucial for regulating various human social behaviors, such as maternal instinct, empathy, and trust. Its secretion in the brain is triggered by social stimuli. Recent research demonstrated impaired regulation of OT secretion and reduced social behaviors in patients with arginine vasopressin deficiency (central diabetes insipidus). OT interacts with other hormones to regulate human trust. Moreover, it has been shown to generate feelings of attachment and trust toward other and familiar consumer brands, thereby, potentially impacting personal consumption, which is a significant aspect of economic activity. This review provided insights into the molecular and neural mechanisms of OT in regulating human social behavior, including both social and economic activities.
