Vasotocin is the precursor of vasopressin. Vasotocin has functions including innervating the limbic–midbrain changes rapidly over evolutionary time in mediating various affiliative and reproductive behaviours. Vasotocin is important in the modulation of stress-related cognitive processes. Vasotocin administration facilitates the learning of a complex (agonistic) song pattern in the wild sparrow.
