Today, scientific and technological progress is advancing by leaps and bounds, but scientists still have not even come to the solution of the mystery of the human brain. This fact does not mean that there was no research. It turned out that the more work is carried out in this direction, the more questions and mysteries arise. The relevance of studying the brain is very important for understanding the manifestation of a person, inherent in him by nature, capabilities, as well as for determining the level of abilities of a particular person.
How large the volume of research can be judged by the fact that there are about 15 billion nerve cells in the cerebral cortex. Each of the cells differs in function and shape, in addition, each of the cells can be associated with at least 10 thousand of its "colleagues". It is not difficult to calculate that cells form a network of over a million connections. And this large number of connections ensure the timely processing of an incredible amount of signals coming from many points in the body to the brain. An amazing quality of the brain is the ability to defend itself against possible dangerous "overloads" that, undoubtedly, can arise during such work with information.
In addition, one of the most interesting abilities of the brain is the acquisition of unique abilities by a person after clinical death or a sudden lightning strike.
It should be said that the origin of colored dreams is still a mystery to scientists. Only some versions are expressed: the first is that the brain conveys what it saw during the day, the second is that this is how a person's memories appear. Both versions have not yet received serious confirmation, since people dream about things that in reality never happened to them. Whether this is somehow related to the existence of a slow and rapid sleep phase is unknown.
But it is not only colored dreams that are of great interest to researchers. The process of "resting" the brain is not clear. If sleep is a rest for a person, then during the REM phase of sleep, the brain is in an active state. Why doesn't he "rest", what is he doing at this moment?
The secrets of the brain include the ability of a person to laugh. The same parts of the brain are "responsible" for the emotion of laughter in different people. Psychologists are completely in the dark: why, what is funny to one person, does not cause any emotions in another.
A person is able to live without a limb, with one kidney, or even with an artificial heart valve, but it is impossible to survive with brain damage. The most dangerous thing is that getting into a situation that will lead to fatal brain damage is not so difficult. So the ingress of a microbe (streptococcus) into the brain tissue (during dental treatment, sore throat, etc.) can lead to brain abscess. The infection can get into the brain even with the usual sinusitis and otitis media. The first symptoms may be headache and weakness, then, hallucinations, mental disorders.
Brain researchers believe insomnia is a dangerous sign of brain dysfunction. A part of the brain called the thalamus is responsible for this part of the brain. It works like a powerful computer, collecting and processing information about the level of sugar in the blood, the presence of inflammation and body temperature, time of day, temperature and humidity of the surrounding air, etc. The thalamus is responsible for maintaining the order of sleep and wakefulness. And factors such as pain, stress and much more - disrupt a person's sleep, respectively, this leads to insomnia. But the most dangerous disease is meningitis. A sign of the onset of the disease is a sharp headache and an increase in body temperature.

A headache is a symptom of a migraine. Many great people suffered from this disease: Caesar, Tchaikovsky, Beethoven, Edgar Poe, Freud, Nietzsche. Despite such a long history of the disease, migraine is not a well-researched brain disease.
So what have our respected scientists - "brain scientists" achieved over many years of persistent research?
Oxford specialists assure that they managed to discover conscience! And it is located in the cerebral cortex just above the eyebrows. They believe that this area of the brain does not "allow" a person to make "bad" decisions. Interestingly, macaques lack such a brain region responsible for conscience. Scientists say that people have different sizes of a lump of nerve tissue responsible for conscience, from tiny to the size of a tangerine. This section of the brain is also responsible for a person's ability to engage in multitasking activities, in which it is necessary to find the right option and calculate all the possible consequences. Also, this part of the brain helps a person learn from the mistakes of others and make the necessary choice between good and evil.
Here's another finding by brain researchers: It turns out that being overweight affects brain function. With an increase in body weight, memory suffers, and with weight loss, brain activity increases and information processing is activated.
Scientists from the University of the Ministry of Foreign Affairs of Sweden investigated the effect of color and caffeine on human brain activity It turned out that the blue color, in terms of the positive effect on humans, is significantly superior to caffeine. In addition, the color blue increases focus and improves memory.
Scientists have refuted the firm opinion and argue that the way to a man's heart goes clearly not through the stomach, but through the brain. This connection can be accurately traced to a person's craving for sweets: some people are euphoric about chocolate, while others are completely indifferent to it. Therefore, the brain is responsible for the attitude to food.
Researchers at the Massachusetts Institute were able to confirm with their works the fallacy of the words: "Something I am slowly thinking …". It turned out that the speed of the brain is eight times higher than previously determined. For example, to memorize a visual image, it takes only thirteen milliseconds, and not a hundred, as previously thought.
Undoubtedly, the human brain is a very complex biological object and its secrets will not be revealed to researchers soon.
