Definition
Vasopressin is a neuropeptide involved in water balance, cardiovascular function, and social behavior. It interacts with oxytocin in shaping bonding, aggression, and stress responses.
Why it matters
Vasopressin sits alongside oxytocin in the neurobiology of social behavior and is often ignored in popular writing.
The Science
Vasopressin influences pair bonding (studied especially in vole models), stress reactivity, and territorial and aggressive behavior. Human evidence is more modest but growing.
The NSI Perspective
NSI treats vasopressin as one of several social peptides deserving honest attention.
Clinical Implications
Vasopressin’s clinical applications are largely in fluid balance; social applications are exploratory.
Practical Application
Human bonding is not one hormone. It is a network. Vasopressin is one of the members.
