Myths and truths about the human brain...

Hi to everyone! Today I will talk about the Doctor Pedro Maldonado’s presentation, and specificly about the “myths and truths about the human brain”.
Well, for starters it is important to mention that the "human brain" is a complex issue, but also wonderfully interesting, because it is the structure of the body that governs all our behavior, including our emotions, for this reason that the human brain is full of myths about which Dr. Pedro Maldonado spoke and clarified in his interesting talk.
Among the myths that Dr. Maldonado said is the "Size and shape of the brain", this issue is very interesting because when compare the human brain with that of other species, are impressive both differences and similarities in the structure and size this structure, for example, the animal that is more like the brain to us humans is the "chimp" and on the opposite side, we find a staggering difference in the convolutions, size, shape, etc., which has an animal as small as squirrels, which have a very small brain, poor convolutions, which realizes the regarding the complexity of functions performed by agencies related to the characteristics of the brain of each species.
Another controversial issue about the brain, is the comparison made of this structure with a computer. Although this myth has been useful in cognitive psychology, neuro sciences research. Cognitive has revealed many important differences between the brains and computers, these differences could be crucial for understand the neural mechanisms of information processing that certainly is much more complex than a computer.
Well finally, it is important to note that the brain is a complex issue and actually engaging, as well as having important for all of us, knowledge of its early development and its functions are essential for understanding many of our behaviors and impressed by how amazing it is the perfection of this structure.

Should we be worried about early puberty?

Hi to everyone! Today I will comment on an article in the online newspaper "The Guardian", the article is named "Should we be worried about aerly puberty?" (http://www.guardian.co.uk/lifeandstyle/2010/oct/19/worried-about-early-puberty).
The article starts talking about a girl, Hannah, who recently turned 8 years old, and his mother feel shocked because she already shows signs of being in puberty (such as the development of the nipples) ecnuentra which she very early, compared to their situation, unlike what has her daughter, she did not show signs of puberty at an early age.
Along with this case, the paper presents other situations in which demonstrates the acceleration of the onset of puberty in children, especially girls the women, where their first menstrual period, which usually occurs long before now than it was in times past. This is evidenced by speaking of figures, since the author mentions that the average age at onset of puberty is 10.75 years in girls and 11.5 years for males (the first sign for children is the enlargement of the testicles).
Within it an important factor mentioned by the author is currently a tendency to obesity and overweight, which advances the age of puberty, in part because the hormonal changes that start are triggered by the body of a children reach a certain size. "It is very likely that there is a link with the body weight increases, but the data is just beginning to show that," says Hindmarsh. "It makes sense, though. In an era of abundance, a species that always has a great interest in self-preservation tends to reproduce quickly."
Other factors mentioned in the article, are the ratio of the advancement of puberty with the "lack of parental presence, since, according to studies, this situation acts as a signal to the brain of pre-teen girls, triggering the hormonal changes that allow it to reproduce.

The increase in female sex hormones come at a time when your brain is not ready. Children at this age usually are in a stage of childhood where they are in the fantasy game, and changes in the brain that are activated at puberty are all about reality and understand that actions have consequences in the long term . This situation becomes very confusing for young children and as the author relates to the tendency to withdraw and other personality disorders that are directly related to how children cope with this new, accelerated phase, which involves many changes, as it moves from being just a child, to live the series of events and changes which means the transition to puberty.

To end the article talks about recent studies that link early puberty to a greater risk of breast cancer, ovarian cancer and heart disease in adulthood. This situation is certainly alarming to us because it increases the rate of those diseases and predisposes to many people because of the advancement of this vital process to be "ill adults".

Dealing with stress...

Hi to everyone! the topic of today is "dealing with stress”.
Well, for starters I will talk about the Meaning of the "stress" concept,the stress "is a Psychological or physical demand out of the usual, causing a state
anxious in the body."
Among the triggers of stress, can be mentioned various stimuli, either internal or external, directly or indirectly determines an alteration in the dynamic equilibrium of the body.
Based on the above, the main causes of stress can be classified in:
-Physiological: These causes are related to disease and injury the body that increase the tension inside the person producing a level stress that it becomes counterproductive to oneself.
-Psychological: relates to emotional and cognitive vulnerability. Life crises by changes: childhood, adolescence, maturity,old age.Conflicting or inadequate interpersonal relationships. Terms frustrating to work or study: excessive demand or competitiveness,monotony,inconsistent standards, career dissatisfaction, etc.
-Social: Social change in which each era brings new challenges face.
-Environmental: environmental pollution, food toxic denatured industrial workplaces with little security or charge electrostatic pathogens, natural disasters, etc.
As stress symptoms the most common are: tightness chest, sweating in the palms, palpitations, difficulty swallowing or breathing, body tremors, cold hands and feet, muscle tension, lack or increased appetite, restlessness, nervousness, anxiety, etc.
In the aftermath of stress we can find some that are very common, and certainly all have felt ever due to some situation, these are fatigue, exhaustion, headaches, tension neck, moodiness and therefore problems in the relationship with others etc.
There are many people in the world who suffer from stress, as it is a serious condition especially common in today, because we live in a world very agitated that predisposes us to be people more stressed and therefore suffer the unpleasant consequences of stress.
In my point view the best way is trying to cope with stress take the time to do different things, not just devote 100% to something if not try to distract doing recreational activities or out of the daily routine.

LEVONORGESTREL

Hi to everyone one more time! in this time I will talk about the LEVONORGESTREL, considering Dr. Carlos Valenzuela's speech.
Well, for starters I will talk about how important was the presentation of Dr. Carlos Valenzuela. In my view this presentation is of great importance to our professional training and for the important data delivered, but it is also important for the reason that we can have an informed view.
Certainly with the Doctor Valenzuela's speech I could understand better his inestigation about the LEVONORGESTREL, as clarified many points and was very educational for explaining how he carried out his work in defense of his hypothesis about the controversial LEVONORGESTREL,also he was very helpful the graphics used statistics to more clearly explain the issue.
The "LEVONORGESTREL" is an emergency contraceptive of very controversial use, known by most people as "day-after pill" and as previously mentioned its use is very controversial, as there are people who consider that is a pill abortive and others not consider an abortive method. From the point of view of Dr. Valenzuela "LEVONORGESTREL" is not an abortive method, because It not affects the implantation of the conceptus in the uterus, and it has effect on the follicle. This drug is used after having sexual relation , seeking to prevent an unwanted pregnancy.
In my point of view, the "abortion" is the termination of pregnancy causing the death of the product of pregnancy, altering the process, whether natural or artificial way, since the embryo has life from my point of view, since the male sperm unites with the female egg (union of gametes). On the other hand an "ectopic pregnancy is a pregnancy complication in which the product of fertilization takes place in different tissues of the uterus, either in the oviducts (more often) in the ovary, cervix or pelvic or abdominal cavity.
As for the terms "Contraceptive" and "Anticontraceptive" I believe that there are two terms that refer to the same, since both are related to prevent conception.
Finally, from my point of view the use of "LEVONORGESTREL" must be highly regulated, because this drug is very useful for extreme cases such as rape, however, must be restraint in its use, the effects and also because controversy has idiológica that the use of this pill has.

About my experience with the blog actitity...

Hi all!, today i'm going to talk about my experience with the blog activity.
Well, for starters I will talk about my most common mistakes, which were mainly the use of auxiliaries to construct sentences, and grammatical forms.

With this activity I could learn a lot, especially learning new words, because the blogs do was to know how many words I did not know before, and learn from my mistakes and having a wider knowledge of the English language.

The topics of the blogs were most closely related to our careers and our professional work, which allowed me person learns English well, think more about what I will do in the future and other issues related to my career. However, I would have liked that issues of free choice or the stories were more than once, to make the activity more dynamic.

A good point is that I have to learn to communicate and post to my classroom.
I think that the advantages of doing the blog were that learn to using the technology and to communicating with other persons across the net.

well, finally, in general I liked this new experience with blogs and technology and the dinamic of the activity.
