The woman’s brain is unique in its kind, anatomically and functionally. Analysis of genetic characteristics reveals much of its uniqueness. Men and women differ in their brain anatomy and functioning of the same. However, for centuries has been the male brain the only universally studied and proposed as a model of the human brain.
Thanks to the work of several researchers who have reviewed the concepts of brain function and have focused their studies particularly in the brain of the woman, now can discriminate the scientific basis that support biological differences in behavior, priorities, emotions reactions and sensitivities that define the female of the human species.
Genetics, brain plasticity and evolution:
Neuropsychiatrist Louann Brizendine According to the Founder of “Women’s and Teen Girls’ Mood and Hormone Clinic”(Clinic for the study of hormones and mood in adolescent girls and women) in San Francisco, United States, men and women differ primarily not only in their reproductive functions but also the uniqueness of the functioning of your brain.
In his book The Female Brain, Brizendine explains the characteristics that define the nature of women since their evolutionary history and genetics, their roles and instinctive abilities and how each feature of his behavior throughout his life is linked to changes in sensitivity, modification and reactivity your brain.
Men and women agree on more than 99% of their genetic code. While the difference is not more than 1%, variations means affect every cell in the human body and every stage of the operation of your nervous system, from the perception of the outside world and the pain through the senses and organs, to the neurons that process emotions, feelings and thoughts.
If this percentage is still close to 1% is not significant at first glance, it is noteworthy that among certain Chimpanzees and man is only a 2% genetic difference.
Or may not be the twentieth, the great dilemma:
The X and Y sex chromosomes determine the human race (males: XY, females XX).
By David H. Skuse (Behavioural and Brain Sciences Unit, Institute of Child Health, London), many of the 931 genes in the X chromosome and have played for 300 million years an important role in the development of sex-specific features and functions of both sexes, is also related to higher mental functions, including intelligence, social communication and emotional regulation, all vital to survival of the human race.
As the woman carrying two X genes, diseases related to dysfunction of the gene X (autism hereditary mental retardation) Are more common in men who have only one X gene and therefore can not compensate for the deficiency.
It has long been considered that sex chromosomes do not fall directly on the development of mental functions but also act through the induction level of gonadal hormone production specific to the particular development of each sex. High levels of testosterone during fetal and neonatal periods would lead to the development of a “male brain” that otherwise would present female characteristics.
However, several studies, including those conducted by Laura Carruth (University of Los Angeles, California) and Craig, I W(Institute of Psychiatry, Denmark Hill, London) reviewed this concept and demonstrated that the XX and XY brain cells differ in their self-development program regardless of gonadal hormone secretion, and that the administration of gender-specific hormones would not change this evolution.
According to Craig, the sex chromosomes can determine for themselves the specific behaviors observed in each of the human race, being the X chromosome responsible for these functions. Human behavior is universal and historical content in our DNA, our genes and, as expected, the different roles that men and women have had since its inception in the face of the Earth, part of their genetic code even today.
Genes and history:
Recently, Taylor S.E(University of Los Angeles, California) showed that the instinctive response of the human face of danger called “fight or flight” is not part of the natural biological behavior of both sexes as previously thought but only of man.
The woman carries in her brain the genetic memory of another reaction instinctive involving a protective behavior of their loved ones, especially children. Event of danger, she would not think of face or escape, since historically the dangers outweighed his physical strength and try to run away meant pregnant, carrying young children and / or elderly.
The goal of women for centuries and centuries has been to protect, communicate and maintain the vital needs of his fellows and his brain has been remodeled to fulfill that role. From Taylor’s perspective, human brain function not only involves a common biology for the species, as some Authors claim, but would reflect the specificity of each gender.
Conclusion:
Brain connections in the brain of women expressing their role and allow instinct remains intact despite the changes of modern life. In his genetic code contained the significance of its role as a woman in the human species.
The female brain is influenced not only by the woman’s genetic uniqueness but because of their special sensitivity to sex hormones and anatomical variation they cause in an interplay of actions that define the woman’s mental functioning and substantially mark the difference between your brain and man.
