Children may learn to distinguish words and they still in the womb!!

-Be careful what you say near pregnant woman . While the baby grows in the womb of the mother, he can hear sounds from the outside world and can be understood in order to  retrieves memories after birth according to new research.

-It may seem implausible that the fetus can be listened to talk, which is still in the womb of his mother, but the centers responsible for hearing in the brain become active in the last trimester of pregnancy, and the sound permeates clearly through the belly of the mother, "If you put your hand over your mouth and spoke, this is the same situation for of the fetus, "says cognitive neuroscientist at the University of Helsinki Bartanan" fetus can hear the rhythm of speech and music and so on. "

-In 1988 study suggested that newborns distinguish beginning song of the daily favorite  series to their mothers. Modern studies expanded the idea of fetal learning, and pointed out that newborns consisted with the voices of their parents language.

-The team gave a recording of a pregnant woman to run several times a week in the waning months of pregnancy, and that includes the word "Tatata" be returned more than once with music. Sometimes the middle section is changing different tone of voice. At a time when children were born they had heard the word that was set up at a rate of more than 2500 times. When it was tested after birth, their brains characterized the word and all the changes which have been, while others were not able to infants.

-Patricia Kahol, neuroscientist at the University of Washington in Seattle Says . Integrating this research with previous work, she says, "that language learning begins in the womb."

-Developmental psychologist Christine Moon, Pacific Oukrn University in Tacoma, Washington, agrees: "I think it's a good look and I think it refers to the way in the future to more detail in the education process."

-Kids who heard the recordings showed neurological response to change of sound and tone of word in the stomach, and the response was strongest among mothers who played more recordings.

 "This leads us to believe that the fetus can learn more detailed information more than what we thought earlier," Bartanan says .And the effects of this memory can be tracked after birth.

Statistics about the oppression of women around the world

1 -  Reports show that the most violence against women during pregnancy period.

2 - every 90 seconds around the world a woman dies during pregnancy or childbirth, most of these deaths can be prevented, but because of discrimination based on gender do not get many of the women on the proper education and care that you need

3 - women make up 80 percent of all refugees and displaced people, often women and the girls who are the target of mass genocides and sexual violence and rape

4 - Woman are great excluded from formal peace operations, only one of 13 participants from peace operations were women since 1992

5 - women got the right to vote in America less than one hundred years ago in 1920

6 - women make up more than 50 % of the world's population, but occupy less than 20 % of parliamentary seats in all the world.

7 - more than 16.4 million women in the world suffer from HIV - the AIDS virus, and in some areas girls are infected at a rate of 5 times for males

8 - women make up the majority of people who are fleeing across the border, many of whom are abducted or sold by their families for "sex industry"

Why Europeans have a white skin?

Why Europeans white skin? Most of us believe that Europe is the ancestral home of the white skin. But a new study shows that light skin, as well as other characteristics such as height and the ability to digest milk for adults, and reached most parts of the continent are relatively recent. It is the matter, presented at the 84th Annual Meeting of the American Association of Physical Anthropology and scientists who displays tremendous evidence of the recent development in Europe and shows that most Europeans do not contemporaries are like their ancestors 8,000 years ago.

The origin of Europeans have focused in the last year when the researchers completion of the genome sequence of the ancient inhabitants [the genome is a map of the genes can be accomplished from any living organism anytime for his qualities], and a large number of European residents old and not a few individuals. Comparing the key parts of DNA (DNA) across the genome for 83 individual Old from archaeological sites in Europe, the international team of researchers at the beginning of this year, said that Europeans today are a combination of mixing at least three ancient groups dependent on fishing and the combination and peasants who They moved to Europe in sporadic migrations over the past 8,000 years.

The study showed that the massive migration of patrons Alimnaya (Yamnaya [came from the current Russia) from the steppes north of the Black Sea might have brought Hindourbih languages ​​(Indo- European) to Europe by almost 4,500 years.

Now, a new study from the same team delves more of these massive amounts of information to search for genes that have undergone selection strong natural appeared [natural selection is the emergence of certain qualities in generations particular sex as a result of their own pace with the circumstance naturally compelling or assistant in reproduction where help these qualities to survive and reproduce ] - including desirable qualities to the point where it spread rapidly across Europe in the past 8,000 years. By comparing the genome of Europeans veterans with modern ones of the 1000 Genome Project, he found a world population genetics (Iain Mathieson), student post-doctoral stage in the laboratory of the world population genetics (David Reich) at Harvard University, found five genes associated with changes in nutrition and skin pigment has come under strong natural selection.

Scientists confirmed an earlier report that the accredited living on fishing and combined in Europe were not able to digest the sugar in milk before the year 8000. Also noticed an interesting development: the first farmers were not able to digest milk. The peasants who came from the Near East (Near East) before almost 7,000 years and the shepherds who came from Germany steppe before almost 4,800 years old lack the gene copy (LCT), which allows for adults to digest the sugar in milk. It was not until almost a year before 4300 that began the ability to digest lactose (lactose tolerance) invade Europe.

Some reasons that prevent you from fully trust your memory

-Title may disturb  powerful memory owners who believe in themselves a great ability to remember the most important details that have occurred in their lives, or who excel so much on their peers when it comes to strong clipboard , and I do not mean frustration morale, or adversely affecting, but there are some reasons back to human nature betray his memory sometimes in spite of their efficiency at many.

-It must be a I had a challenge with one of your friends in one day on remember certain details of the incident, or game you were playing... etc., and eventually one of you may come right answer, or the answer would be contrary to the views of everyone, and you wonder to yourself why forget the other, others remember.

This reasons may be

1. tendency in humans to remember the bad details

It notes the great effect of bad memories when most people, it remains one of us suffers depression for years because of a bad accident one happened in his life, while a lot of good situations may occur with us, but we do not find him in a state of permanent joy.

We have no right to blame in our memory, because this tendency will be a strong factor may protect us from bad experiences go again, but it certainly is a major cause in the prospect we describe past events( absolute negativity) while they were not.

2-bias of what we choose

Details about when we mention something we bought ourselves or choose to change the memories tend to talk about our choice as the best choice, completely the opposite of the option, which we rejected,

For example, when we buy a car of a certain type, and refuse to buy another car of a different kind, we tend to mention details that praised the first, second and vilify, a tendency to many people, no motive to only appearing look good and avoid the wrong choice results, it's human nature without doubt.

3. the effect of entry into a new room (Doorway effect)

Each one of us has passed this position many times certainly, for example, be in your room, and think to go to a nearby room to fetch something, what to cross the door so forget what is that thing!

What happened with you is natural does not mean you are weak memory, but our brains are trained to leave the thinking in old memories when entering into another environment, so as to build a new memory and collect updated information about the new centrist which we moved to, even if this move from room to room other.

4. phenomenon (on the tip of my tongue)

It is one of the phenomena that you get with each of us about once a week, and at a greater rate in the elderly, as it tries to remember the player's name in a certain team, or an artist, or otherwise, but you are not able, or perhaps remember the first letter of the name, the form of the player and his team for example, but you fail to mention his full name.

The reason is that the names are stored in a type of memory called Read Memory (semantic memory), which stores information in a network of various links, in this case this partial formed memory does not include the sound that speak to signify the thing that we  Forgot.

Chemistry of Love .. How do the brain fool you with the name of love?

-Most of us Pass a strange period, to look to a certain person ,admire him,you feel compelled to this feeling, and trying to answer the important question: "Why exactly this person?".

-The matter in it that you as a person and as a human being can not understand why this person attracted to exactly, but the nice thing is that your brain knows where this attraction came from. 

-This attraction has been felt because the brain (figuratively)  favored specifications useful to the evolutionary level (such as the attraction of women for the long man,attractive or owner of the money, or men who prefer Beautiful women without awareness of them.

- Could we buy the love? .. Well why not!

And now follow us the journey towards brain loving:

The stages of love:Love at first sight passes to marry or link stages can be summarized in three stages as follows:

-stage I: the desire

The brain sees a certain person shall be signs in the secretion of hormones testosterone and estrogen to qualify attraction to this person.

-stage II: attraction

At this Phase , you are under the control of three chemicals, "dopamine" It makes you happier, more energetic, then "serotonin" It makes you crazy (you will notice doing crazy and strange things, this hormone is the reason), and "adrenaline" that makes your heart beats fast with severe sweating also makes you attentive to the words of your lover accurately.

This is the stage the stage of adoration. When people fall in love, do not think about anything else. The even they lose their appetite for food and sleep less, preferring to spend hours dreaming of the time Conscious Dreaming about a new lover.

-

-stage III: link

It is what will determine whether the relationship will continue after the attraction stage or not, association long-term commitment, a bond that keeps couples together when they are having children

At this stage, the brain secretes two hormones:

-Oxytocin: breast, which also helps the secretion of milk, also helps to strengthen the bond between mother and child.

Also it is excreted from both sexes during orgasm, and thought it promotes bonding when adults during the meetings intimacy.

-Vasopressin: that makes a person more tolerant of sincerity and responsibility for lover to preserve the breed, where enhances the bond between parents and children.
