Do you bond?

Want people to trust you more or want to make an impression on your first date- try this!

For someone like me who is in love with the subject of social bonding but not have had the time to stay up to date with it, this seminar was perfect.

Larry Young started his seminar with an introduction to monogamy. Did you know that while ~90% of bird species are monogamous, less than 5% of mammals exhibit monogamy? Anyway his talk focused on molecules oxytocin and vasopressin. They are both hormones and neurotransmitters. If you do not already know, oxytocin is a key hormone in stimlating milk ejection when a baby feeds and stimulating uterine contractions during birth. While these aspects of oxytocin have been quite well characterized, recently it has been shown to be involved in establishing maternal instincts and pair bonding nature (Larry Young studies the neurobiology of pair bonding in prairie voles).

I thought he made an interesting evolutionary correlation by suggesting that in females pair bonding is an extension or adaptation of the maternal instincts while in males it is more an adaptation of territorial behaviour that is controlled by vasopressin, a hormone that is very similar to oxytocin. Males have more of vasopressin which is associated with their territorial and aggressive behaviours. If you paid attention in your high school biology class, you would know vasopressin as the antidiuretic hormone (ADH).

He showed data to support his argument- basically in prairie vole females that bond there is more oxytocin and in males there is more vasopressin. There are all correlative confirmations. An interesting conclusion comes from a study where they made mice which lacked oxytocin and showed that these mice suffer from something that is known as "social amnesia". David Adam has this to say about that study in Nature News-

"Love is chemical and so, it seems, is remembering it. Male mice missing certain brain proteins cannot recall which females they have had sex with. The forgetful fellas can blame this unfortunate amnesia on their DNA: a missing gene means their 'social' memory fails them."

Yet another interesting paper by Kosfeld and others, suggests that oxytocin plays a role in trust in humans, I know it just gets better and better. They put their subjects in to two groups- investor and trustee, basically a financial situation. The subjects were either sprayed with oxytocin or a placebo. Below is a part of their abstract (their work was published in Nature, 2005)

"Trust pervades human societies. Trust is indispensable in friendship, love, families and organizations, and plays a key role in economic exchange and politics. In the absence of trust among trading partners, market transactions break down. In the absence of trust in a country's institutions and leaders, political legitimacy breaks down. Much recent evidence indicates that trust contributes to economic, political and social success. Little is known, however, about the biological basis of trust among humans. Here we show that intranasal administration of oxytocin, a neuropeptide that plays a key role in social attachment and affiliation in non-human mammals, causes a substantial increase in trust among humans, thereby greatly increasing the benefits from social interactions."

I liked Young's talk for one more reason- he was FUNNY!

Having commitment issues, trust issues- the be-it-all-have-it-all hormone might be your way to go.

Better yet banking folks should spray us all with it, may be then we would begin to trust the world financial institutions better! Well a few companies (check the link from the first sentence of this post) have already capitalized on it- a typical capitalistic attitude- BEWARE! Remember it definitely is not the know-all-end-all of this issue, if you wait just a few more years there might be a super-enhanced version of "Liquid Trust" for y'all to try!
