..."Myths and Truth about the Human Brain”...

Hi, everybody!!

In this opportunity I talk about, of excellent presentation of Dr. Pedro Maldonado, about the myths of the brain

First, the brain is a very particular structure, charge of the correct operation of own organism, and so far unknown, but with the advances of medicine has been studied, to discovered the capacities, morphology and real functions of them

The size and form of brain, was thought different compared with others species of animals, because the grade of human intellectual develop, allowed reach the levels of modernization, creation and capacity of thought, but now, we know that there is no difference between animals and humans, both have the same structures and morphology, the difference lies in the size, the number of circumvolutions, not more.

Also, the brain always is compared with a computer, for the capacity of stored or the distribution of information, other myth resolved! Because our brain has a certain plasticity and is able to integrate the events rather than separate them

The human brain not present differences for the gender, the male brain and the female brain have the same capacities, it’s to say, women have a brain less abstract, but with all their skills to use in learning, the differences are most related with hormonal factors, but the brain is equal in both

I think, it’s very important know the functions and characteristics of human brain, understand this complex organ, very difficult to study, and clarify the myths to have a view most extend about what it’s the real role in the organism.

... INMUNIZATION...

Hi everybody!!
I talk about a very interesting article about vaccines and immunization.
Article is available in:http://www.guardian.co.uk/lifeandstyle/2010/oct/11/vaccination-fears-developing-world-deaths

The news talks about the many people are afraid of vaccines, pain, needles, and lately by the diseases they may cause, because immunizations are associated with the development of dangerous diseases such as: the vaccine against hepatitis B, multiple sclerosis occurs, the component Mercury in other vaccines cause autism, the MMR vaccine (measles, mumps and rubella) (included in the immunization program in Chile) is related to whooping cough, etc.

But none of this is proven, they are just rumors spread around the world, developed countries like France, UK, USA. through internet.However, it is relevant, because less industrialized countries, mainly from Asia and Africa (the highest rates are in South Africa and India), reject the vaccines even if they have high numbers of people who die or become ill each year.

Our fears of anti-vaccine groups created to excel in the developed world can not directly cause these problems, but "nurture and amplify them," said Dr. Heidi Larson of the vaccine program and policy group Imperial College London

What to do? so far only been designed to educate, inform and raise awareness, but not sufficient, it is necessary to make the change at the country and end the rumors, better known in each

For the other hand, there are places that progress in immunization, such as South America, has a high number of people vaccinated, even a relatively poor continent, including countries such as Bolivia, Peru, every year increase their numbers

Is very sad to be put at risk hundreds of lives by poor dissemination of information, and every day innocent people are dying, victims of the ignorance of those who decry the benefit offered to modern medicine for better health, especially in those need and are at a disadvantage.

Hi everybody in this opportunity I talk about Stress!

The stress is a set of physiological, psychological and behavioral characteristics of our organism to stimuli or situations that we perceive and interpret as a threat or danger to our physical and psychological.

Hundreds of people around the world suffer from this problem, even in Chile the figures are increasing daily, especially in the female population, and also in the young population

In the case of health students, this situation is habitual, but at the same time prejudicial to the health
The principal causes of stress are:
The competition in the work, the work pression, frustration for not meeting expectations, the accelerated pace of life, economic problems, problems in the family
In conclusion, several factors can trigger this condition
But is relative and accord at the people personality and mood

The symptoms of stress are varied, but the most significatives and frequent are: headache, insomnia, irritability, confussion states, incapacity of concentration, among others
The normal is that stress have a short duration (days, weeks) adaptation and solution to problems must end at this
When the stress becomes chronic (does not go away) can have long-term and in various systems, and present diseases such as high blood pressure, ulcer, depression, is to say, a series of diseases become vulnerability at the organism
The best form to fight with the stress, is evite the stressing situations, planification the change in the life , organize priorities, improve communication, discover our limitations, getting enough rest, and most important develop a positive attitude
This last recommendation can make a difference in the daily rutine and alleviate the burden of the day
