The Brain is the Masterpiece of Nature

The brain, like the whole human body, is the result of a multimillion-dollar evolutionary modification. Personality, talent, intelligence, logic, character, all these and many other features of human essence are reliably stored in its bowels, as well as, however, information that a person remembers and with which he works. In this regard, very often the brain is compared to a hard disk of a computer, the so-called hard drive, which also has the ability to store structured data. But this is not true. The biological concept embodied in the brain is very different from its technical counterpart. The information in it is transmitted with the help of a set of intertwined cells called neurons, which enter into communication with each other through the means of the finest synapse connections, through which an electrical signal passes. Information in this form is the result of concepts, judgments and inferences, and is stored in the form of images that are associated with each other associatively. These images, which are professional, scientific, entertaining information or memories that enter memory in the process of human activity, are obliged to confirm their significance by paths that are formed from neurons, when electric signals pass through them. This happens when, for example, a student repeats a lecture, or simply scrolls through the life memories in his head. Also, thanks to these tracks, not only information is stored in memory, but a skill is also created. To perform movement, for example, by hand, electrical impulses are sent from the brain to the muscles of the hand. Signals enter the hand, and return back to the brain, creating this kind of route model. With repeated repetition of movements, the signal becomes more familiar and it is much more convenient to traverse this route with each repetitive movement. The same can be said about playing a musical instrument, performing acrobatic movements, and even memorizing a poem. The skill arises only if the action is repeated several times.

Thus, the whole body depends on the electronic impulses that the brain controls, and it does it quite rationally. He achieves a special condition when the body gets into an extreme situation, where the brain is obliged to work for survival. In times of danger, when a person intends to flee (for example, from an unexpected forest fire, etc.), the brain gives impulses to the adrenals to excrete adrenaline, that is, in a similar way, it temporarily strengthens the muscles, which increases the productivity of the entire body. As a result, the heart begins to work harder, the blood stops feeding processes that are not needed at the moment for salvation, for example, digestion, but more and more enters the muscles, saturating them with oxygen, thereby creating conditions close to the most favorable for the survival of the organism. The brain can even slow down the time, if necessary, however fantastic it sounds. The fact is that the average person can see no more than 30 frames per second. In emergency situations, the brain increases this indicator to get more data in less time, as a result, and appears, in a way, the illusion of slowing down time.

The brain also decides what we eat. The need for food, still being in the first place in the Maslow's pyramid of needs, as a physiological need, is also born in the brain. If there is such a need, then the brain has already "scanned" your body, and revealed the absence of certain nutrients, vitamins, etc., which must be obtained with food. If their body is not received for a long time, then the instinct of survival works. The brain begins to secrete orexin, the hormone of wakefulness. It is necessary to maintain the working capacity of the body for the time it takes to extract food. If, however, a long time, a person still could not get it, then the body goes into "autonomous mode". The brain begins to "regret" spending energy on other organs, in order to maintain its own performance. Thus, we can safely say that the brain is the most important organ in the body and consumes a quarter of the energy of the whole body.

The human brain works almost continuously, so it has the ability to heat up. In a normal state, the average brain is heated 1 degree per every 5 minutes. It is cooled by blood, which transfers heat to the surface of the skin, after which the sweat evaporates from the face and forehead.

The brain works also when a person sleeps. The mystery of the dream is still an open question in science. With the onset of night, a small gland in the brain contributes to the release of a natural sleeping pill - melatonin, which acts on the nervous system, causes drowsiness. The brain cells worked all day, but at night they need restoration work. When the body is disconnected, each cell of the brain literally comes to life, as a result of which the brain programs various visions and situations that, when interacting with disconnected logic, can open a person's eyes to solving previously unresolved problems. For example, Einstein, thanks to sleep, where he slept at the speed of light, discovered the theory of relativity, Niels Bohr, thanks to a dream about horses, understood what the atom consists of, Salvador Dali, claimed that in some pictures depicted the content of his dreams.

The brain is a whole universe weighing 1.5 kg, the secrets of which humanity is just beginning to learn.
