Does the brain have a sex?

History has undeniably proved to us that man was capable of becoming an astronaut, artist, Nobel laureate and even a state leader. And if we talk about intelligence in men and women, there is no difference …

However, the skillful hands of the Biology has not only allowed men and women to have a different physical appearance, but has also differentiated them by certain characteristics in the brain.

So, is there a feminine gender and a masculine gender?

1 – Female origin

Let's review a small point of genetics: while women have XX chromosomes, men differentiate slightly because they have XY chromosomes.

But that was not always the case at the time of our creation, because from conception until about 8 weeks of fetal life, we all had female-type brain characteristics.

Once past this period, the tiny testes of the male fetus begin a revolutionary process that will be critical in its development: the release of large amounts of testosterone that will enter his brain and that will attribute to him its male gender.

This is an amazing process by which every existence in this world begins. We start by sharing the same nature, a stage so fast that we do not remember.

2 – Female brain, male brain

The "sexualization of the brain" does not stop at the moment of birth but continues. Indeed, hormones continue to permeate our body through a very interesting process that scientists call "infantile puberty".

Thus, in boys, the testosterone level is constantly increasing, from their birth until their 7 or 9 months, and then slow down again, while in girls, estrogen stagnates until their 2 years old.

Little by little, the brains will assert themselves more and more until they reveal structural and behavioral differences, which can not always be observed thanks to magnetic resonance.

To begin, we could say that men and women have some kind of "hardware" that works differently. The male brain, for example, being larger, can solve problems using the temporo-parietal junction of its brain, which allows it to find solutions more quickly.

In contrast, women generally develop better emotional intelligencebecause their hippocampus (structure where emotional aspects are stored) is slightly larger than in men. Added to this is the higher number of emphatic mirror neurons, which generally translates into a larger emphatic process and more developed communication.

3 – Are we slaves of our hormones?

What we are, and what we express, does not necessarily come from our neurons, nor from that capricious biology that dictates and makes us a man or a woman.

It is certain that hormones predispose us and mark us. However, we are thinking beings and we are capable of thinking.

We learn by developing a little more every day our limbic system. Predisposed or not, we remain free to think, feel or act.
