In observation of the Valentine's Day...
From (CNN) -- Dr. Brown said scientists believe that when you fall in love, the ventral tegmental floods the caudate with dopamine. The caudate then sends signals for more dopamine.
"The more dopamine you get, the more of a high you feel," Dr. Brown says.
Or as her colleague, Dr. Helen Fisher put it: When you fall in love, "exactly the same system becomes active as when you take cocaine. You can feel intense elation when you're in love. You can feel intense elation when you're high on cocaine."
Male brain - female brain
In their work with the lovestruck, the scientists found brain differences between men and women.
"The men had quite a bit more activity in the brain region that integrates visual stimuli. This isn't surprising considering that men support the porn industry and women spend their lives trying to look good for men," says Dr. Fisher.
But she adds there's probably a more anthropological reason at work. Simply put: A man's evolutionary mission is to spread his seed. That won't work if he mates with an 80-year-old grandmother.
"Men have to be able to size up a woman visually to see if she can bear babies," says Dr. Fisher.
The women's brain activities were a bit more puzzling.
The scientists found that women in love had more activity than men in the areas of the brain that govern memories. Dr. Fisher theorizes that this is a "female mechanism for mate choice." There are no visual clues for whether a man is fertile, but if a woman really studies a man and remembers things about his behavior, she can try to determine whether he'd make a reliable mate and father.
Thus, if it sometimes seems like a woman remembers everything -- good and bad -- about a man, "it's not just her being picky. It's an old Darwinian evolutionary strategy."
Lets all get really HIGH today! Love you all!
