With age, women are smarter than men?

All business, according to scientists, sex hormones

It is not a secret that these little brisk substances hormones - the most that neither is on the "gray cardinal" of the body. It depends on them metabolism and our mood and even brain activity.

Researchers from Northwestern Medical School, United States claim that with age the brain cells of women work more actively than men. And it happens at the expense of female sex hormones - estrogens, which are produced by the female body in much larger quantities than the male. These hormones contribute to the renewal of neurons and stimulate mental activity.

Estrogen is produced primarily by women's ovaries, and a small number produced by the adrenal glands in men and women, and male testes.

Peak production of estrogen between the ages of 25 to 35 years. Then they reduced production in both men and women. But in the male body, this process is much faster. And 45-50 years female brain is more active than that of men.

BTW

The weight of the female brain is 12% less than men, but the blood supply to it in 1, 3 times more active. Scientists from the University of Pennsylvania examined in the MRI scanner 200 people aged 18 to 80 years and found that the male brain tissue wear at 1, 5 - 2 times faster than the female. And the greatest changes occur in the left side of the brain responsible for control of speech.

In general, the male brain - less reliable mechanism. Through many parts of the female brain for the same period of time it takes 15% more blood than the same parts of the male. Perhaps because of this, the stronger sex are more common strokes and Alzheimer's disease.

After 45 years of neurons (nerve cells - the "little gray cells", as he called them to Hercule Poirot) male brain begin to be updated 1, 5 times slower than in women. Because senile dementia (dementia) faster and more popular with men.
