- The human brain has the capacity to store up to 4.7 million books.
- Although it represents only 2% of the body weight, it uses 20% of the intake and oxygen of the whole body.
- It is also one of the five fundamental organs that a person needs to stay alive.
The human body is one of the most complex machinery that exists. Each of the organs has a specific function but in the end they all collaborate with each other. For its part, among those that make it up The brain is a fundamental part of life and that is why we are going to share with you some curious facts that you should know.
To begin with, the human body is made up of 78 organs. Within all there are five that a person needs to stay alive: the brain, heart, liver, at least one kidney and one lung. If any of the aforementioned fails, it irremediably leads to death.
For its part, the National Autonomous University of Mexico (UNAM) describes the brain as the main element of the central nervous system (CNS). It is located inside the skull, submerged in the cerebrospinal fluid that protects it. It is estimated that it has an average weight of between 1.3 and 1.5 kilograms in an adult person.
Although it is related to most of the functions of the body, it is responsible for intelligence, the interpretation of the senses, the control of behavior, learning and the initiation of body movements. It also controls other functions such as breathing and heart rate.
Evolution throughout history
As part of the fun facts about the brain, has seen an important transformation throughout the evolution. Nematodes, fruit flies, zebrafish, salamanders, mice and monkeys have fundamental similarities with the human nervous system. While one of the biggest differences is the ability to reason.
The brain is so important that, although it represents only 2% of body weight, it uses 20% of the intake and oxygen of the entire body. The greatest demand for energy comes from neurons, which depend on glucose. It consumes 5.6 mg of glucose per 100 grams of brain tissue per minute, and its work continues whether we are asleep or at rest. With the energy generated by the brain, a 20-watt light bulb could be turned on.
On the other hand, it is made up of 73% water, so even 2% dehydration will cause parts of the brain to swell and make simple, monotonous tasks difficult to complete.
And it is also made up of 60% fat. So the people who carry a diet low in Omega 3 fatty acids are more prone to accelerated brain wear.
capacity of the human brain
The human brain can store up to 4.7 million books, ten times more than originally thought.
Scientists discovered that, on average, a synapse can contain about 4.7 bits of information. This means that the human brain has a capacity of one petabyte, or 1,000,000,000,000,000 bytes. That’s the same as 20 million four-drawer filing cabinets full of text, 13.3 years of HD-TV recordings, or 670 million web pages.
