Are we different men and women?


It is obvious the "external" difference between men and women, but is there A difference in our behavior, and having it in our brains, what is it?

Male-female differences

The difference in the different performances between men and women that are manifested in adulthood, is due precisely to sexual dimorphism, product of the masculinization of the brain in Man, which begins with the production of testosterone from the seventh Week of life. These differences will be manifested in that:
Women will be better equipped to use language strategies, manifested since the first years of life, speaking earlier, more fluently, easier to learn reading and writing, better visual memory and speed Perceptual (Object identification
Men on their part, will have greater aptitude for spatial tasks, manifested already during childhood, having better results in the tasks of recognition of forms, rotation of objects mentally and with the representation of objects in two and three Dimensions.

Recent studies have concluded that the differences previously described, are due both to a different brain organization, and to a differentiated use of the brain in each sex
Thus the male brain has a larger size than the female, but there are also differences in:
-A larger size and with more neurons in the man, in the hypothalamus, in the anterior corner and in the corpus callosum.
-A larger size and with more neurons in the woman, in the anterior white corner, in the posterior part of the corpus callosum and in the locus coeruleus.
Equally at the level of dopaminergic receptors there are differences, having a greater number of them in female brains compared to males. Remember that dopamine is involved in the emotional and pleasure functions
But these differences do not remain only in the size of the structures, but also affect how they are used, thus it has been observed that the men use more the regions temporo-limbic (involved in the memory and the motivation) and the cingulate in the Women ( Involved in emotional processing).
At present, the "function" of these differences is not yet clearly established, and there are different opinions about it, among those who claim that it is something "inherited" from our ancestors that remains thanks to natural selection, while Others say it is a social construction that is shaping the children from the cradle, creating expectations and treating children differently, so at least evidenced the experiment of baby X.

The Baby X

In this experiment was used a baby, which was dressed in blue and deposited in a blue cradle, and was observed how they treated the adults, and then, the same baby was visited in pink, and put him in a pink crib , and other adults were observed. The conclusions could not be more evident, it was observed how the adults change their way of treating it according to whether it is a child (baby dressed in blue) or a girl (the same baby dressed in pink). So the little one was considered stronger and more active, while the small, more sensitive and delicate, even the tone of voice, the way of relating, and the greater or lesser physical contact of the adult, varied according to the belief of the sex of the baby.
As we see there is a clear differentiation from the establishment of the gonads, which will trigger a whole cascade of reactions in the organism, which will establish the body and brain of man, when the Y chromosome is present. But the effects of testosterone are not only going to be determinants during development, but also in parental behavior, at least this is affirmed by a recent study conducted by Emory University of Atlanta (USA) published in Proceedings of the National Academy of Sciences, which analyses the preferences of men and women in relation to the desired partner.


Differences in gender preferences

This study first notes that men prefer women with wide hips and a small waist, with which the odds of procreation are increased. Instead, women vary according to their ovulation cycle, so they seek to reproduce a man with marked male characters, own high testosterone levels, while for their care prefer men with soft lips and chines, without Those masculine traits.
Once corroborated what was already known by previous studies, have analyzed the brain activity of 70 men before the presentation of faces of babies intermingled with others, being observed with functional magnetic resonance.
The study concludes that men with more masculine traits (due to high testosterone levels) show less interest in babies and involve themselves with the domestic chores that this entails, while men without so much male accentuation are more Likely to be responsible for raising the young.
