Where did you get the number 75? You posted in NeuroPharmacology. Do you think there is a love drug? Is love more than a shared feeling?

Based on experiences with certain drugs and reading some of the literature, love is probably some kind of combination/modulation/regulation of (also depending on the type of love); dopamine, noradrenaline, serotonin, oxytocin, vasopressin, endorphins, sex hormones. Any that I've missed?

100% of people get married and love by the work of their brains.

There's an interesting section on how sex leads to an increase in social bond formation (Figure 2), or 'love' for you romantics out there.

seeing as how valentine's day is coming up i thought id bump this thread =)
i think orbz covered pretty much the array of neurotransmitters that play a role in love, with oxytocin i believe being one of the most important. it has ben shown (i believe) that oxytocin has alot to do with monogamy, forming lasting bonds and 'love'. however, id like to think, and i believe im correct, that as far as love is concerned, that while 99.9% of it may be explained by neurotransmitters, that there is a tiny piece that is still a mystery and one of the greatest unsolved mysteries among human kind. the greatest drug of all...love.
