Arginine vasopressin (AVP) neurons are essential hypothalamic neurons that produce and release the neuropeptide vasopressin (also known as antidiuretic hormone, ADH). These neurons play critical roles in osmotic homeostasis, cardiovascular regulation, stress responses, and social behaviors. Central vasopressin signaling is increasingly recognized as relevant to neurodegenerative disease pathophysiology, particularly through its effects on the hypothalamic-pituitary-adrenal (HPA) axis, circadian rhythms, and autonomic function.

Anatomy
Location
AVP neurons are primarily located in: [@bhardwaj2021]
Supraoptic Nucleus (SON): The largest population, located in the hypothalamus above the optic chiasm
Paraventricular Nucleus (PVN): Smaller neurons with parvocellular and magnocellular divisions
Bed Nucleus of the Stria Terminalis (BNST): Involved in stress and social behavior
Medial Preoptic Area: Regulates social and parental behaviors
Projections
Central AVP neurons project to multiple brain regions: [@javed2016]
Posterior pituitary: Axonal terminals release vasopressin into systemic circulation
[Hippocampus](/brain-regions/hippocampus): Modulates memory and spatial navigation
Amygdala: Regulates emotional and social behaviors
Septum: Influences anxiety and social recognition
Brainstem autonomic centers: Controls cardiovascular and respiratory function
Neurophysiology
Vasopressin Peptide
Vasopressin is a nonapeptide (9 amino acids) with disulfide bridge:
Sequence: Cys-Tyr-Phe-Gln-Asn-Cys-Pro-Arg-Gly-NH2
Synthesized as preprovasopressin, cleaved to active peptide
