A recent article in new scientist debunks the idea, of male and female brains. After scanning more than 1,400 brains, scientists at Tel Aviv University revealed there is no difference between male and female brains. Although male brains are known to be bigger, than female brains the features inside that brain do not differ greatly.

The idea that, when a baby boy is developing in the womb, and when testicles are formed these discharge testosterones which defines the brain as male, has now been disproved by research.

When the research group in Tel Aviv looked at 1400 magnetic image residence scans of subjects between the ages of 13 and 85, they found very little variance between male and female brains.

One interesting, spin off from this research is that the team found is that there are variations in the size of brain areas, as well as the interconnections between them. The researchers found 29 brain regions, but in general seem to be of different sizes between people who identify themselves as male or female. These include the hippocampus, which is involved in the laying down of memories and an area of the brain, which is considered to play a major role in risk aversion called the inferior frontal gyrus.

When the researchers looked at individual brain scans they found that they had very few people that have all the brain features they would expect, based on their sex. In fact, across the 1,400 brain scans, the research looked at, between 0 % and 8% of the people had all male or all female brains depending on a definition used in the past.

It is thought that we all somewhere along the continuum, with a mix of brain attributes that would define as individuals.

Researchers at the University of Tel Aviv commented saying that most people are in the middle.

 

Gender myths

Men are preoccupied with sex.

Many studies have verified that men have more casual sex than women. Nevertheless, the female sexual appetite may be underestimated. Women in general are likely to downplay the use of pornography or masturbation while men tend to exaggerate their use.

Women tend to be bigger gossips than men.

Is a common held belief that women are better communicators than men. The reality is gender difference in verbal abilities is very small. In fact, in some posts specific skills, men outclass women.

Boys are better at maths than girls.

An analysis of 240 studies found that girls and boys are equally matched when it comes to maths. The variable is girls tend to perform as well boys in countries where there is more gender equality.
