Nine myths and truths in the brain that you should know



The brain remains a big unknown.

The brain is still a big unknown, even to its own researchers. The great advances in neuroscience have more than ever spoken about him, but so much information has given rise to myths or lies, in many cases, of scientific interpretations, fears that conscious intentionality has a negative impact on their knowledge.

Then he says it in an interview Francisco Mora, a doctor in medicine from Granada University and a doctor of neuroscience from Oxford University in connection with the release of his book "Myths and the truths of the brain"; (Paidós), as he aims to bring this confusion to an end with knowledge of the brain.

"We will never learn the intimacy of what our brain is like today, we can get the general idea of ​​what it is and that is what is provided by current research programs but trying to understand how it works is like trying to get up the floor and try to throw away our shoe laces ", Arma specialist, lists a number of myths and truths that should be known about him:

1. In order to better understand what is being said, Mora explains what the brain is: "It's a body with a very special evolutionary process: 4 million years ago, when we were chimpanzees, it weighed 450 grams to the present genetics, it's got a kilo weight thanks to the review of Evolution we have acquired the cognitive capacity and ability to convey feelings and emotions, which is what characterizes us as humans. "

2.- Why is it so important for the body's function? As he points out, the brain is a body in our body such as the liver or kidney, for example, but it is "Organizer". "It is a body that must constantly be fed with all the chemical substances released by each body from the rest of the body that enter and modulate their function to adapt the unity of the organism" It indicates.

3.- Are all brains the same? Is it true that the man and woman in adulthood are different in size? "All brains are different, each of them different from each other, like every individual on Earth, and there is also no normal brain or pattern, there is no such thing as there is no identical brain to the other. man and woman, but they are born of the hormonal system that has transformed it " explains Infosalus.

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

4.- The brain weighs only 2% of the total body, but should consume 20% oxygen that we breathe so that the necessary energy for the operation is produced.

5. Can neurons be created until the end of our day? Yes, we can be born with a number of neurons, between 80,000-100,000. But it is true that new neurons can be created in the hippocampus throughout their lives. Everything is related to the type of memory of things or events that are very close and similar. Some 25-30,000 neurons are born every day, although everything depends on the lifestyle, what is eaten, about social relationships, about the exercise that is performed, and depending on this, they will be born more or less. But they also die fundamentally because of their lifestyle, "says Mora.

6.- We only use 10% of our brain capacity? No weapon there "Absolutely false" and that man uses 100% of the brain. "The anatomical whole of the brain is necessary 24 hours a day to exert the changing functions assigned to the individual's survival" also adds a professor of human physiology at the medical faculty of the Complutense University of Madrid.

7. Is it true that the experiences and lessons learned during the first 3 years of life determine our future? No, it's another myth. He says that these three years are important, but it has been seen that he is not yet able to absorb abstract concepts.

8. What about the right brain and left brain? Mora distinguishes between the right, which controls the left part of the body, from the left part of the brain that controls the right part of the body. "There is a myth that says that the right part of the brain is holistic, more feminine, of art, of emotions, the part that maintains creativity. Meanwhile, it is said that the left part is the executive as we write, read or do the math. But that is not the case. There is no cognitive function of one side of the brain. Corpus Callosum, a million bra, going from one side to the other, becomes constantly informed of what happens, so the whole brain is a device ", comments.

9.- Basically, the explicit or episodic memories of the hippocampus are stored, the conscious memory. However, the memory also indicates changes. "The memory we have about something will probably change what's really happened and there are different kinds of memories, the iconic example that allows us to save a phone number, there are different types" comments.
