"brain regions rich in oxytocin and vasopressin receptors overlap strongly with those rich in dopamine, the neurotransmitter classically associated with the brain's reward system. Young and colleagues propose that long-term partner preference occurs when the vasopressin circuits, which are also known to mediate individual recognition, somehow connect with the dopamine pathway, causing an animal to associate a specific individual with a sense of reward. In key dopamine-rich brain regions, vasopressin V1a is expressed more highly in monogamous than in promiscuous mammals" ...
"I think it's emerging that the mechanism of attachment preference uses the dopamine pathway to make attachment a rewarding experience."maybe worth a read. Also it fits with the feeling I got when I tried tyrosine in a large dose (2g). ...gotta keep post in alter :-)
