Whats The Difference Between Yahoo And Ymail?

question of sex (1)

Reflection of the day to day scientism @

Yesterday I had an epiphany well ... no. But what if you found out was that apparently the battle of the sexes is still open and that there is great ignorance about the biological differences between men and women and what they really mean, at least at the level of behavior. So if you want to dig a little beyond the "Why men do not listen and Women Can not Read Maps" keep reading, but if you look you fight mistaken, this is not about pro-feminism or defense of the superiority of the male.

The first and if some do not have it @ clear: men and women are different.

Apparently men and women think this way: Would you believe it?

Since the behavior is determined by the nervous system have to be differences in the construction of it which explain this divergence that if we ignore the strong influence of education and the role of cultural roles, of course. In 90's the sociobiologist Edward Wilson summarized the behavioral differences between the sexes: men would be better at math and spatial location (abstract thinking) and behavior tend to have a more independent, dominant and aggressive while women against be higher in language, artistic and aesthetic as well as possibly more emotional and empathic ability. This could explain why, for example, there are professions where there is a clear majority of men and aircraft pilots or engineers as there are other predominantly female (psychology, nursing ). But are there any tangible evidence to support these differences?

has been shown that men and women process information, manage emotions and use language very differently. In the literature on the topic is often referred to differences in size: the brain to the complete, certain areas or even in terms of number of neurons but I think the fundamental difference is that we must refer on functionality and it is given by connectivity changes in brain architecture, not necessarily by size. Moreover, in general, the size differences disappear when corrected factors such as differences in body size, weight and other physiological variables such as muscle mass difference between the sexes but to be faithful to the data (without compensating for factors mentioned above) the average male brain is 10% higher than the female and has 4% more neurons, but there are more connections between neurons in the female (ref. 1).

Different brain ultrastructure: men (left) are more subject gray (body neurons), while women (right) have more white matter (nerve fibers).

In recent years the advent of new imaging techniques like functional magnetic resonance imaging (fMRI) have allowed to study in detail the nature of these differences. Thus several independent studies showed anatomical differences in various brain areas, eg in the areas of Brocca and Wernicke-both related to the understanding and natural language processing, was observed in the brains of these areas were more women bulky which would support the superiority female partner thought to language (ref. 2 and 3 ) has also been described in reference to verbal language that women use both hemispheres simultaneously to process words while men use only the dominant hemisphere (left in For right-handed), although curiously the same study found that eastern employing ideographic language (symbolic) regardless of gender use both hemispheres simultaneously (ref. 4) how to explain this similarity, Mr. Wilson?. ; Around the interhemispheric communication in women greater controversy exists as to the architecture the corpus callosum, which some studies have found higher in women (ref. 5 ) while others do not seem to have found significant differences (ref. 6) but a study published last year which is to argue is that microstructural difference is fundamental, cellular level, but in any case this new evidence supports that in women interaction between the two hemispheres is stronger (ref. 8).

contrast inferior parietal lobe (IPL) which is a structure located symmetrically on both ears, seems to be more developed in males and size seems to correlate with mathematical ability. Part left relates to the perception of time and space as well as the ability to rotate shapes in space while the right has the ability to understand spatial relationships and the relative position of various body parts. In fact, the importance of this area in abstract thought seems to corroborate because postmortem studies have found that Albert Einstein and other mathematicians and physicists have a great development in this area. (Ref. 7 )

Not better or worse: VARIOUS.

But one of the questions we really want answered is why we react so differently when faced with an emotional conflict? Or face the pain? therefore, not all studies have focused on studying the cerebral cortex, which is responsible for more complex cognitive functions, other study has addressed the limbic system, more related to control / lose control of emotions.

However, this subject deserves a separate chapter.
To summarize: Today science has shown that there are differences between men and women at the biological level but it is not clear yet (although the theory proposed by Simon Baron Cohen on the effect of testosterone during embryonic development) is what is the origin of these differences is it due to the effect of chromosome YvsX, the effect of certain hormones or rather a social-cultural product?. Nor are these differences
the argument for intellectual superiority judge not only the result of the widespread (and not all women have problems with math and all men are incapable of handling the language) but also correlates at the behavior of these differences are highly influenced by external variables such as education, culture and social stereotypes, as discussed in another occasion.

Love and other chemical processes

Although in fairy tales (and in Hollywood films) make us believe that love is forever and that monogamy is natural de facto ago voles years taught us that monogamy actually depends at least in part, on genetic variation in the gene vasopressin, a hormone that also acts as a neuropeptide that is, they can influence neuronal activity and thus on behavior but not today I speak of this hormone but his cousin's oxytocin also appears in fairy tales but a little before The End and that some have called the "love hormone" but as real life is not just good and pink.

The reason for the good name of oxytocin is because this hormone is secreted in large amounts by both men and women during orgasm responsible for the link is said between lovers but also is secreted during delivery thus ensuring the mother-child bond. In fact rats unable to secrete oxytocin reject their young (1) . But the funny thing is that even our perception of the relationship with our mother in the presence of oxytocin varies: people who are going through a time of personal distress and have doubts about their social relationships tend to remember their mothers as distant and less affectionate than those with security that the positive memory of their mothers is emphasized. (2)

has also been shown to increase confidence but not under any circumstances, Carolyn H. Declerck demonstrated in a cooperative game that oxytocin only made people more cooperative if they knew their partner had previously played surprisingly when a stranger made them oxytocin less cooperative.

And right now, a group of scientists from the University of Amsterdam has found that after exposure to oxytocin we become more aligned with our group (in this case) ethno-cultural and more reluctant towards others, in other words increase our sense of belonging to a group ("us vs. the rest"), which in evolutionary terms the authors explain as a means of promoting community life. (3)

Then the hormone of love "can also cause hate? in fact this apparent contradiction is not so surprising when you consider that the neurohormonal system connected to the emotions work in response to many factors that vary not only temporarily in the life of an individual but also with regard to cultural factors, example. In the case of oxytocin receptor (OXTR), the variant that in theory gives its holders increased sociability and sensitivity produces a consistent behavior in people but not Korean American. The former tend to seek help in bad times, while the latter do not because such an attitude is socially reprehensible (4) . Thus we see how the medium shapes the biology and define why una molécula en términos tan genéricos como "molécula del amor" es casi tan absurdo como intentar venderla como medio de potenciar el éxito comercial, evitar el divorcio o ¡¡hacer más felices a las mujeres!!
