The human brain is complex and mysterious, and we haven't been able to unlock all of its secrets.

In this report, which was published by the Turkish newspaper Milliyet, the writer Tosun Pasha presented amazing facts about this member.

1- The brain is more complex than a supercomputer

The "K" computer is the world's first supercomputer produced by Japan, and it is known as the fastest and most powerful computer with 88,000 processors and its ability to perform 10.51 quadrillion calculations per second.

To be able to do this, this computer uses as much electricity as a medium-density city.

This computer was used to run a 2014 experiment that attempted to simulate just 1% of the neural network of the human brain, and it took 40 minutes.

Computer K stopped working in 2019 due to the availability of more advanced supercomputers.

But even the new supercomputers do not have the ability to simulate the performance of the complex structure of the human brain.

2- The huge memory capacity

In 2007, Canadian Dave Farrow set a world record by memorizing 3 thousand and 68 cards of playing cards in just one session in 59 suits.

In 4 hours, 58 minutes and 20 seconds, he was able to count the papers he had memorized and made only one mistake.

In fact, the human brain is capable of setting an even greater record.

According to the Salk Institute for Biological Studies, the digital equivalent of a human brain's memory size is equivalent to 1 petabyte of information.

That equals 20 million 4-drawer chests full of written paper.


3- Half a brain is enough

The extent of brain development does not depend on its size. Sperm whales, for example, have a brain 6 times larger than a human brain, but they are not ranked among the most intelligent of creatures.

A person can live with half a brain, and while removing a part of the brain has negative consequences for adults, it turns out that children adapt to this condition more easily.

4- It does not contain pain receptors

Physical injuries stimulate pain receptors, and the hypothalamus is responsible for activating sensory signals.

These signals reach the parts of the brain responsible for sensation, thought and emotion, and thus we feel pain.

But the strange thing is that we do not feel pain when the brain is injured, because it does not have pain receptors.

There are no pain receptors in the brain itself.

But the meninges (the coverings around the brain), the periosteum (the coverings of the bones), and the scalp all have pain receptors.

Surgery can be performed on the brain and, in theory, the brain does not feel this pain.


5- Acquired synesthesia

Synesthesia is the integration of two or more senses, the most common case being the integration of colors and numbers.

People with synesthesia see some numbers as colours.

The famous physicist Richard Feynman, who won the Nobel Prize in 1965, had previously stated that he saw equations as colours.

One in every 300 children is born with synesthesia, but if the brain is not trained to develop this ability, it will fade over time.
