IF YOU thought depression was caused by low serotonin levels, think again. It looks as if the brain chemistry of a depressed person is much more complex, with mounting evidence suggesting that too much serotonin in some brain regions is to blame.

tamarinsMonkeys in enduring relationships show a surprising correspondence in their levels of oxytocin, a key behavioral hormone,
according to research published online June 28 in the journal Hormones and Behavior.

While measuring oxytocin in the urine of 14 pairs of cotton-top tamarins,Charles Snowdon, a University of Wisconsin-Madison professor of psychology, observed a wide range of hormone levels.

But he also saw a striking correspondence among the couples: When one mate had a high level of oxytocin, so did the other, and vice versa. Furthermore, partners with a high level of oxytocin performed correspondingly more cuddling, grooming and sex, while those with low levels of oxytocin spent less time on these relationship-building activities.

It sounds like a miracle drug, so how does one get their hands on it? Perhaps, simply by tweeting.

Older people are less likely to be hot-headed

Wisdom really does increase with age, say scientists.

Although the brain slows down, this simply helps older people to develop greater insight which helps them cope with the problems of life and take on new challenges.

Unlike hot-headed youngsters, elderly brains are less ruled by brain chemicals that fuel emotion and impulse, claim scientists.

SLAVE MASTER: How Pornography Drugs & Changes Your Brain

Submitted by gary on

A pretty good article on porn addiction from an MD/neuroscientist. It covers a lot of ground, and makes some points, that we don't. It's posted on a religious magazine website. Nothing wrong with that, except they also have anti-evolution articles. Not much moralizing in this article, though.
I do disagree with his views on oxytocin as a part of the addictive process.
