heartbrokenExperts are beginning to measure the physiological hangovers of "love," so the time may be nearing that we can look at the physiological hangover buried in the passion cycle after orgasm.

Love Hormone Boosts Strangers' Sex Appeal

oxytocinNotice how neurochemicals affect our perception. It is not far-fetched to suggest that they may be playing a major role in habituation or harmony between mates.

Love Hormone Boosts Strangers' Sex Appeal

Oxytocin Could Play a Key Role in Choosing Mates

A chemical best known for cementing the bond between a mother and her newborn child could also play a part in picking mister (or miss) right.

Round 2: Turning Heterosexuality On and Off

Round 2: Turning Heterosexuality On and Off

By John Tierney [2007]

The post about using a drug to change the sexual orientation of fruit flies — and some day, perhaps, of humans — generated lots of indignant reactions and questions about the research. I asked David Featherstone, one of the authors of the paper in Nature Neuroscience, to respond to Lab readers. Here’s what Dr. Featherstone, a neuroscientist at the University of Illinois at Chicago, has to say:

Turning Homosexuality On and Off

Turning Homosexuality On and Off

By John Tierney [2007]

What if you could take a drug that would quickly alter your sexual orientation from straight to gay, or vice versa?

To their surprise, neurobiologists have discovered that homosexuality can be turned on or off in fruit flies. They’d known that sexual orientation can be genetically programmed, but they didn’t realize it could also be altered by giving a drug that changes the way the flies’ sensory circuits react to pheromones.

Scientists find 'pleasure nerves'

Scientists say they understand more about how the body responds to pleasurable touch

A team, including scientists from the Unilever company, have identified a class of nerve fibres in the skin which specifically send pleasure messages.

And people had to be stroked at a certain speed - 4-5cm per second - to activate the pleasure sensation.

They say the study, published in Nature Neuroscience, could help understand how touch sustains human relationships.

Kisses unleash chemicals that ease stress levels

Rodin's KISSCHICAGO – "Chemistry look what you've done to me," Donna Summer crooned in Science of Love, and so, it seems, she was right. Just in time for Valentine's Day, a panel of scientists examined the mystery of what happens when hearts throb and lips lock. Kissing, it turns out, unleashes chemicals that ease stress hormones in both sexes and encourage bonding in men, though not so much in women.

Sex and Depression: In the Brain, if Not the Mind

Finally, a psychiatrist is acknowledging that intense orgasm can create a hangover for some people, without any apparent psychological issues. Maybe as professionals begin to explore the neurochemistry of extreme cases they will realize that the same neurochemical fluctuations are at work in more subtle ways in the problem of habituation between couples (as well as sex addiction).

Scientists discover true love

playful coupleHmmm... It's interesting that the scientists looked at "mature" couples, who are known to have less friction in their marriages (on average) due to cultural expectations about marriage in their childhoods. As other researchers concluded in a very large study across different generations (which showed a steady decline in marital happiness until death),

When David Duchovny entered rehab for sex addiction, he drew attention to a condition with devastating effects

During his second marriage, a man we’ll call Walter Logan had three or four affairs a year, every year, throughout the entire decade he and his wife were together. When the Vancouver lawyer wasn’t screwing around or indulging in pornography, he masturbated several times a day
