The human brain is a miracle of the miracles of the Creator. Science is still trying hard to recognize its nature and how it works and to simulate what happens inside the brain. What the science learned up to the moment about the brain is a very simple percentage of brain secrets.
In this subject, we will learn about some of what science has learned about the human brain.
What is the difference between brain and mind?
The brain is known as Cerebrum and represents the bulk of the human brain and about 85% of its total weight. The brain controls the central nervous system (CNS) via the spinal cord. He is responsible for almost all human activities.
So what is the mind?
The mind is a term that describes the functions of the intangible brain for each person. Such as character traits, memory, behaviour, thinking about world affairs, religion, analysis and decision making.
Brain: Unusual facts.
The brain during the day produces electrical energy about 12-25 watts and is enough to light a small lamp!
Approximately 100,000 chemical reactions occur within the human brain per second.
Attention span increased from 12 seconds in 2000 to 8 seconds, less than the goldfish’s attention span.
Neurons: A world within a world.
The human brain consists of about 100 billion neurons and 1 trillion glial cells. Which is equivalent to half the number of stars in the entire galaxy (about 200 billion stars).
Neural signals travel within the brain at about 420 km / h and are faster than the fastest car in the world.
The brain contains too many blood vessels that can be estimated at about 750 km.
Did you know that Albert Einstein’s brain weighs about 1229 grams and is about 10% smaller than the average human brain weight.
The power of the superhuman brain.
If the human brain is a computer, it can process 38 trillion processes per second. It is the fastest 500 585 times the fastest supercomputer in the world.
In 2015, the fourth most powerful supercomputer in the world needed about 40 minutes to simulate one second of human brain activity.
The storage space of the human brain is “infinite” and can not be filled with the other, unlike computers or other.
The brain processes about 50,000 thoughts ideas within one day, and 70% of them are believed to be negative.
Do we really control our decisions? A person believes that he has complete control over his life, while 95% of the decisions come out of the subconscious mind.
How does the human brain work?
The brain can not perform multiple tasks at the same time (Multi-Tasking). But what happens is that the brain makes a quick switch between each and every operation, such as talking on the phone and writing a message. This process has been shown to have a negative effect on brain performance.
Sleeping pills really do not make us sleep but they put the brain in a coma-like state. Thus, the brain or body does not benefit from the benefits of sleep in this case.
Forgetting is useful to the human brain, as getting rid of useless or necessary information helps the nervous system maintain its efficiency.
Alcohol does not help to forget at all. All that happens is that the brain loses the ability to record events temporarily. Brain cells need only 6 minutes to respond to alcohol.
Characteristics of the human brain.
The average human brain weighs 350-400 grams (at birth) and 1300-1400 grams per adult. The brain rate is about 2%.
The human brain uses about 20% of the total oxygen and blood in the human body.
The brain consists of 73% water and 60% of the solid mass of the human brain is fat.
The human brain needs to pump blood mainly to work. About 20% of the blood in the human body is directed to the brain, and passes through the brain about 1000 liters of blood per day.
Does the intelligence of humankind diminish over generations? The average IQ of the human race (IQ) has been decreasing against belief at a rate of 13.35 points between 1889 and 2004.
During rest time the brain uses 1/5 (five) calories per minute.
The brain contains 25% of the cholesterol in the body. It exists in every cell of the brain without which these cells die.
If your brain loses normal blood pressure for 10 seconds, it will fade immediately.
An oxygen break from the brain for 5 to 10 minutes causes permanent destruction of the brain or large portions of it.
Is the man’s brain different from the woman’s brain?
The man’s mind is about 10% larger than that of a woman.
The human brain prefers the state of mental stimulation continuously, especially men. Where they prefer exposure to electric shock from sitting in silence and practice meditation and thinking!
You need ladies to take a longer decision about men. But they are also more assertive because of their different brain composition than men.
Studies have also shown that the average size of the human brain has decreased over the last 20,000 years, in proportion to the size of a tennis ball.
Does the human brain feel pain?
Despite the treatment of the brain to sense the pain we are experiencing of different types, but the brain itself does not feel any pain because there is no sensory receptors pain.
Brain cells have defensive behavior in securing their source of energy. In severe hunger strikes the cells can eat themselves!
The brain deals with rejection decisions in the same way as physical pain.
Studies and experiments showed that the brain uses full strength even during sleep.
Brain and cooling process!
Yawning is believed to be a way to send more oxygen to the brain and also a way to cool the brain if it gets warmer.
The brain can handle high temperatures without noticeable effect. The highest temperature recorded was for a man with a fever of 46.5 degrees and did not die.
Is the brain social?
Each time we record a specific memory, the brain creates new cells and neural connections.
Connects to each nerve cell about 40,000 nerve tangle points.
Not all brain cells are the same type, there are about 10,000 different types of neurons in the brain!
Healthy habits help your brain.
Siesta can increase the efficiency of the brain during the day, where it has been shown that sleeping in the middle of the day for 30 minutes helps increase the ability to focus and remember the rest of the day.
The smell of chocolate increases the waves called theta inside the brain and it helps the person to relax and clear the mind.
Seafood is the most useful food for the brain, which helps to boost memory by 15%.
Exercise and exercise regularly help the brain to focus and increase the sense of happiness.
Brain from childhood to maturity.
The children’s brain is severely damaged by domestic violence and is equivalent to the same damage done to soldiers during war.
Reading aloud and talking to a child regularly helps develop your child’s brain growth.
The human mind grows and develops and reaches its best until the end of the age of the 1940s, after which it begins to stabilize.
