Blog 5: A discussion of a scientific paper

This time my blog will be on one of the myths found in the present work and Dr. Pedro Maldonado about the brain on Tuesday just past, where the myth is: "But I read somewhere that we only use 10% of our brain anyway."

Well, I think this myth is totally false, since people need to use more than 10% of his brain to find some situation, for example when a singer has to give his concert before the audience, you must activate several places your brain, because the singer has to look at people, also need to remember the song memorized, you listen and has to speak, so while parts of his brain must be working, and if only work a 10% of his brain would not be possible. As described by Dr. Maldonado this would have been seen with imaging techniques, where several brain regions would be linked together for understanding and production for example of language so that a situation would trigger a specific area of the brain, but also trigger secondary regions to be understood as a whole.

As stated by Dr. Maldonado is said that each neuron is surrounded by about ten glial cells, which explains the myth, however it has been determined that these cells are those that give nutrition, stability and protection neurons, therefore, in my opinion, despite the fact that neurons occupy a smaller proportion of the brain that glia, the two are complementary. Since neurons without glial cells could not function or fulfill the function of producing nerve impulses that carry information and connect the different parts of the brain.

Blog 4: Stress

In this occasion I will write about what I think about the stress.
Well, that I mean by stress as a clinical condition is that the stress is given by an increase in anxiety over a situation which can vary depending on the person. Some of the most common symptoms that can identify a person with stress include stomachache, fatigue, tiredness, irritability, sleep problems, among others. An example of this may be the students before an exam is felt by some nervous, others feel stomachache, others give more like going to the bathroom, everyone reacts differently to as stressful situation.
According to what I believe, affects women more than men, because they are more susceptible in some periods of the month by hormonal changes. And according to Dr. Enrique Jadresic, president of the Society of Neurology, Psychiatry and Neurosurgery at the Clinica las Condes, stress affects them more because both the autonomic nervous system as it is axes neuroendocrinos are more sensitive.
The labor productivity is greatly affected, because people are not totally focused on the activities to be performed, perhaps because they feel discouraged or can not concentrate and think on how to solve the problem they feel, them work becomes secondary.
The most common causes of stress may be a concern, the work load, avery long time, any untoward or any difficult problem.
The most typical ways of dealing with stress according to my opinion are sleeping well, exercising and eating healthy, if that fails clearly there to visit a doctor.

Blog 3: Healthy lifestyles

In this occasion I will write about the person who have a healthy lifestyle.
People who lead healthy lifestyles, have different habits that Hill allow a good quality of life, among them we find the exercise, diet, do not use substances such as alcohol and drugs (at least not in excess)

A person who carries a healthy lifestyle is concerned with eating a healthy diet that meets certain requirements, such as being balanced, incorporating fruits and vegetables, not eating junk food, eat at fixed times and drink enough water.
Also concerned about making any kind physical activity, it must be at least three times a week for about thirty minutes.
Achieving healthy styles brings many positive effects on people is lives, such as disease prevention, a better mood and good self-esteem among others.

People who have a generally healthy lifestyles goes on holiday to place where they can breathe clean air, such as beach, field, mountain, or places where they can engage in recreational activities. However, any of these places you choose to go on holiday will need to bring appropriate clothing to weather and to the possibilities of carrying out the activities you decide to.

Today unfortunately, it is very difficult to maintain a healthy lifestyle, this is because the pace of life that takes, for example for most student, it is difficult to make any kind of physical activity primarily due to lack of time.
I do like to do some physical activity, but during the day there are classes, when I get home it is too late and should be further studied.
