It was news in 1992 that scientists discovered a skeleton of “human origin” 4.4 million years old in the country of “Ethiopia,” which is considered the “oldest” ever found.
It is a new species in the “human family” called Ardipithecus Ramidus, nicknamed “Ardi”. The female weighs about 50 kilograms and is about 1.2 meters long.
Before Ardi, the oldest living “human family” and the most famous is Lucy, classified as Australopithecus afarensis, 3.2 million years old, and discovered for the first time in 1974, also in “Ethiopia,” about 72 kilometers north of the area where Ardi was found.
The story arose when scientists hypothesized that humans evolved from “bipedal origin,” the Homo family of Sapiens, Erectus, and Neanderthals.
Making World History In the past the name Lucy has been used on many occasions as a “human model”
Especially the movie “Lucy, Lucy is Beautiful and Killer,” which compares Lucy to the heroine of the story. Brain bright from the accident. This caused her to receive chemicals to stimulate her brain to be able to “use 100% brain efficiency.”
Recently, researchers from the Max Planck Institute in Germany in collaboration with the Basel Institute for Clinical Molecular Ophthalmology and the Swiss Federal Institute of Technology discovered it. The process of using the human mind has revealed that it differs from other primates, such as the great ape family such as chimpanzees, orangutans, and gorillas, although they have a common ancestor.
In particular, the famous theory “Humans only use 10% of their brains” attributed to American writer Lowell Thomas. Which he wrote popularly in the book How to Win Friends and Influence People by Dale Carnegie in 1936
Professor Dr. William James of Harvard University is considered the father of American academic psychology. He once said that ordinary people can evolve and can only use their intelligence level at 10% of their total potential.
Since then it is unbelievable that just a short sentence and in such common words, it became a “belief” in the form of “scientific tales” spread by word of mouth. Widely spread throughout the world from generation to generation
It is unbelievable that in the following times, so many people gathered together. “I strongly believe that humans do not use their brains to their full potential. It only uses 10% of the brain’s total capacity.
Especially many science fiction stories. Even many Hollywood films have expanded this concept into the plot or main story of the film, such as the science fiction film “Lucy, Lucy, the Destroyingly Beautiful”.
Although scholars, especially psychologists, cannot prove the father of American psychology. Did you mean what you said or not?
But what is true and certain is the claim that the saying “humans use only 10% of their brains every day” is completely scientifically incorrect.
Dr. Julie Fratantoni, cognitive neuroscientist Researchers from the Center for Brain Health at the University of Texas at Dallas in the United States said that the belief that humans use only 10% of their brains is a “ridiculous myth.”
“Although the human brain is divided into different parts, whose tasks are clearly separated but in practice the brain works through networks in many ways. That connects many parts of the brain together.”
For example, the network that turns on automatically when the body is at rest or the default mode network (DMN) that often steps in to help process thoughts. and social interaction”
Dr. Julie Fratantoni summarizes
As well as Assistant Professor Dr. Erin Hecht, an expert in developmental neuroscience. From Harvard University, he gave an interview to Live Science saying: “We humans always use our entire brain. Use every part available.
“They say people only use 10% of their brains. That’s a lie. It’s very vague,” said Associate Professor Dr. Erin Hecht.
“Because I don’t know what that 10% is. It means 10% of the energy generated by metabolism or 10% of the movement of electrical signals in the brain or 10% of the oxygen level in the brain.”
“10% of what exactly?” said Assistant Professor Dr. Erin Hecht.
“When students ask this in class, I usually answer that people who use only 10% of their brain are mostly unconscious. And those who use a ventilator are only for life support.
“Our mind is like our heart. It works all the time. Even when we sleep, neurons in the brain still need to work. To always fire a certain amount of nerve impulses,” said Assistant Professor Dr. Erin Hecht.
“The authority will set minimum standards. It is an order for the neurons to always make small electrical movements, even when we are asleep, to keep the neurons in a healthy state. It still works well.”
But if we want to know how much brain use we humans have in each period of time. It’s not difficult at all. Assistant Professor Dr. Erin Hecht said:
With current medical technology we can find out how much we humans use our brains every day through “brain scans”.
This is because a “brain scan” using an fMRI or fMRI can show images of movement and changes in blood flow to different parts of the brain. While there are clearly motivating things
Assistant Professor Dr. Erin Hecht said:
“Using an fMRI machine, we can see that blood is constantly circulating in the brain. If any part of the brain has too much blood flowing to it, that is the part of the brain that is being burned. It uses more energy than other parts of the brain because it processes What we focus on. Or think seriously at that time.
“However, some parts of the brain may consume energy or resources. It is reduced from the body if we already have certain skills and experiences related to using this part of the brain well,” said Assistant Professor Dr. Erin Hecht.
Naturally, the parts of the brain we use most often will be larger. As neurons spread to communicate with other neurons, more blood vessels will be created in those areas to support additional use.
“As a result, the functioning of this part of the brain is highly efficient. It consumes less energy. It may seem that they do not move much,” said Assistant Professor Dr. Erin Hecht.
And to claim that the statement “humans use only 10% of their brains” is not only biologically incorrect. It is also a concept that lacks a great deal of understanding of how the brain works.
“This can be proven by some patients’ brains being damaged. Whether from an accident or a stroke they can regain their skills. Different performances can be restored,” said Assistant Professor Dr. Erin Hecht.
“Because the rest of the brain has adapted to take on other responsibilities instead.
“Don’t forget that our brains are plastic. It can always change the connections of neurons and this allows us to use it with 100% efficiency.”
With amazing network elements inside the brain. Assistant Professor Dr. Erin Hecht concluded.
