The Male vs. Female Brain


I read this little excert today from a health magazine and thought it was funny and slightly informative!

It explains so much...

The Opposite Sex's Brain: What You Need To Know

Yeah, you knew there were differences. Especially during football season. But a brief tour of how men's and women's brains develop may help you understand where the other sex is coming from, especially when it feels like it's another planet.
Seems men and women didn't start out differently at all: Until 10 weeks of fetal development, every brain is female. Then, in boys, a huge surge of testosterone hits the brain, killing cells in the communication center (you noticed, eh?) and growing cells in the sex and aggression center.

Neurologically, because of the testosterone, the male fetus typically lags 3 weeks behind the female at birth. (This early testosterone poisoning does come in handy later because it helps some coordination neurons develop better, making males more adept at catching moving objects, such as animal prey and baseballs.) So when babies are premature, females are usually much better off neurologically. The evolutionary reason? Females are more precious to a society because of their childbearing potential, but men are expendable, since one man can impregnate multiple women (though we're not recommending that).

Because of this, brain development is built more precisely in females, meaning there's less variation in how girls' brains develop. On the other hand, nature doesn't have to be so meticulous when making the male brain, so there's a wider variety of ups and downs -- a variability that manifests in more autism and a broader intellectual curve. Nature, in effect, can roll the dice more during male brain development; the results are sometimes better, sometimes worse.
