Nine myths and truths of the brain you need to know



The brain remains unknown.

The brain remains largely unknown, even for its own researchers. The great progress in neuroscience made today more than ever talk about him, but so much information has given grounds for myths or lies, fruit in many cases of scientific interpretations, which, knowing intention, have a negative impact on their knowledge.

So he says in an interview Francis Mora, a Doctor of Medicine at Granada University and a neurologist at the University of Oxford on the occasion of the publication of his book "Myths and Truths of the Brain" (Paidós) with which he aims to put an end to this confusion about brain knowledge.

"We will never know the intimacy of our brains as we do today, we can have a general idea of ​​what it is and it is that provided by current research programs, but trying to understand how it works is like trying to get out of floor, trying to throw our shoes on, " The Arma Specialist, who lists a number of myths and truths that must be known for him:

1.- In particular, in order to better understand what is said, Mora explains what the brain is: "It is an organ with a very special evolutionary process: 4 million years ago when we were chimpanzees, it weighed 450 grams, then to the present genetics, it gained weight by the passage of Evolution, we acquired the cognitive capacity and the ability to transmit emotions and feelings, which characterizes us as human beings. "

2.- Why is it so important to the functioning of the body? As he points out, the brain is an organ of our body, such as the liver or kidneys, but it is "Organizer", "This is an organ that must continually feed on all the chemicals released by each body from the rest of the body that enter and modulate its functions to fit the unit of the body, This shows.

3.- Are all the brains the same? Is it true that man and woman in adulthood are different in size? "All the brains are different, each is different from the other, like any individual on Earth, nor has a normal brain or pattern that is, there is no such thing, no identical brain of the other, between man and woman, but they are born of the hormonal system that transformed it, " explains Infosalus.

3.- Is there the ability to change throughout life? Yes, there is what is known as its ability to mutate or the concept of neuroplasticity of the brain. "The brain is never the same, it changes from one minute to another and is constantly changing because we constantly learn and remember, which changes the physics and chemistry of the brain.

4.- The brain weighs only 2% of the whole body but needs to consume 20% oxygen that we breathe so that it produces the energy necessary for its work.

5.- Can neurons be created by the end of our day? Yes, we can be born with a series of neurons between 80,000 and 100,000. But it is true that new neurons can be created throughout the life of the hippocampus. Everything is related to the type of memory of things or events that are very close and similar. About 25-30,000 neurons are born every day, although it all depends on lifestyle, what is eaten, social relationships, exercise, and, depending on it, they will be born more or less well, little. But they also die, mainly because of their lifestyle, "says Mora.

6.- We use only 10% of our brain capacity? No, this is the weapon "Absolutely fake" and that man uses 100% of the brain, "The anatomical totality of the brain is needed 24 hours a day to exercise the changing functions assigned to it for the survival of the individual, adds another professor of human physiology at the Faculty of Medicine at the Complutense University in Madrid.

7.- Is it true that experience and learning made during the first 3 years of life determine our future? No, that's another myth. He says these three years are important, but it is obvious that he is still unable to absorb abstract concepts.

8. How about the right brain and the left brain? Mora distinguishes the right controlling the left side of the engine from the left part of the brain that controls the right part of the body. "There is a myth that says the right part of the brain is holistic, more feminine, art, feeling, a part that keeps creativity. At the same time, it is said that the left part is the executive power with which we write, read, or do mathematics. But that is not the case. There is no cognitive function on one side of the brain. The body calosum, a million bras that pass from one side to another, are constantly informed about what is happening, so the whole brain is a unit, remarks.

9.- Essentially explicit or episodic memories are stored in the hippocampus, the conscious memory. But according to the instructions, the memory also changes, "The memory we have for something will probably change what has really happened, and there are different types of memories, for example, the icon that allows us to store a phone number, has different types, remarks.
