Our brain is an amazingly complex, with billions of elements that every second produce about one hundred, two hundred or three hundred signals. The brain is often compared with the computer, but scientists today still have a better understanding of brain function and the comparison seems to be inadequate. The brain is basically a chemical rather than an electrical system. Numerous chemical reactions are taking place at each station, which is quite different from the principle of a computer work. In addition, no one is programming the brain, it is the body that anticipates and resolves problems in advance, and it works by itself, unlike the computer.
When you are sleeping, your brain is so smart to protect your body from doing what you dream. If you dream to run, your brain knows you are dreaming. About 12 percent of people dream in a purely black and white variant, while others dream in color.
- 1.3 kg weighs the average human brain.
- 4 to 6 minutes the brain can be oxygen-free before it begins to die.
- For 8 to 10 seconds it is necessary to lose awareness of the loss of blood.
- 75 percent of the brain is water.
- 161,000 kilometers is the length of the blood vessels in the brain.
- 1,000 to 10,000 synapses (where the signal is transmitted from one nerve to another) is located on each nerve cell in the brain.
- 100 billion nerve cells are in the brain.
The brain, by itself, has no pain receptors and therefore can not feel the pain. Common headache is not caused by the stimulation of such receptors in the brain.
Although some animals have a larger brain, such as an elephant, the human brain accounts for 2% of the total body weight (ie 0.15% of the elephant), meaning that people have the biggest brain in terms of body size.
Children who learn two languages before the fifth year change the structure of the brain, and as adults have denser gray matter. If you read aloud or often talk to young children, you encourage their brain development.
On average, people have 70,000 thoughts every day. Alberta Einstein’s brain was similar in size to most other people. But areas responsible for mathematics and spatial perception were 35% wider than the average.
