The neuromyths



One of the myths that Doctor Maldonado talks about in his work is that the people only use the 10% of their brain. This myth has two origins one of them come from of an experiment realized in 1930's that was about electric shocks and how the brain react to them. From this experiment it's conclude that only the 10% of the brain was use because only some parts of the brain react to this experiment. The other origin of this myth was that the people confuse the numbers of glial cells in the brain with the neurons (that are the ones that can make synapses) and for this they think that we can only use the 10% of it because only are 10 glial cells for one neuron.

But all of this is a lie because the neuroscience findings show that we use the 100% of our brain and that the brain it's always active even when we sleep. And this can be show in the case that a person loses the 90% of their brain tissue we can observe that this person will present serious consequences. If the people only use a little part of the brain this tissue damage should not affect them but really affect their brain activity.

I have hear about this myth before but I have dudes about this because is illogical think that such an important organ requires its entire function to make all the function in all our body.

I think that this article is very interesting and help the people to know that some of the things that its said it about the brain are false. I think that the most interesting thing is that the neurons can regenerate themselfs and reduce the damage that can are made to our brain.

Work Stress


The stress is a problem that people present when they feel overwhelmed for the work's and academic's demands and for this pressure they can have psychological and physical problems that reduce their performance and affects their emotional stability.
The most typical symptoms of stress in the physical area are: chest tightness, stomachache, dry mouth, muscle tension and lack of or increased appetite. In the psychological area the most common symptoms are: Restlessness, nervousness, anxiety, fear, irritability, mood swings and depression.
There are two ways to treat the stress: one is the biomedical way which is prescribe anxiolytics or the psychological way that include the biofeedback techniques like breathing and relaxation exercises. The people can mix this ways of treatment to get a better result.
The stress is caused for the problems and concerns of everyday that the people sometimes cannot control and the problems gets bigger and bigger to the person.
In the work the stress can produce a decrease in labor efficiency, can deteriorate the work relationship and this create a bad work environment that only increase the symptoms caused for the stress.
In my opinion the people can try to control the stress not overstretched themselves. Also the people can try to have a little of time to have fun or make relaxation exercises that can help to relax and improve the mood of the people. If the people feel that they can control the stress they can search help in the physician or psychologist that can provide the tools to make better this situation.

A healthy person

In our society I believe that is possible have a healthy life style and all depends of the people because if all the people try and realize that the health is important can change some routine or take the necessary time to improve this aspect of their lives.
I think that to be a healthy person you don't have to eat only vegetables and make many exercises because you can eat a little of everything, in a good measure, and make the necessary exercises, that not only can be the exercises that you do in a gym but others things like yoga, and you still can have a healthy life style.
In my opinion the people that take care of what they eat, make little exercise, try to live their life without stress and go to the doctor when is necessary, are healthy people.
A healthy person can have the habit of eat more healthy food or have a healthy diet without deprive herself of eat other food least healthy (but not a lot of that food or only that food) and the person can make different styles of exercise and take time to relax and have a good time to not stress herself.
I think that this kind of person can go to the beach or to the country in the holidays because in this way the person can relax and take the necessary time to recover all the energy that require to go back to the job or studies.
