The brain is the central part of the nervous system of animals and humans, providing the most perfect forms of regulation of all functions of the body, its interaction with the environment, higher nervous activity, and in humans, higher mental functions.
The brain is made up of nerve tissue: gray matter (a collection of mainly nerve cells) and white matter (a collection of mainly nerve fibers).
To solve the same problems in representatives of different cultures, the same brain regions are activated. This is not entirely true. Psychologists have long pointed to differences in the outlook and characteristics of memorizing information among representatives of, for example, American and East Asian cultures. While the former exhibit features of some isolation and independence, the latter have a collectivist approach to problem solving. The results of experiments in which Asians and Americans answered the same simple questions lead to the conclusion that representatives of the two groups use different parts of the brain to search for answers.
With a certain diet, you can grow wiser. Indeed, some foods (chicken eggs, fish oil, beets, etc.) enhance cognitive abilities, as they contain substances that have a positive effect on brain function. But it should be borne in mind that experiments with a "diet to improve the mind" were carried out only in laboratory conditions on experimental animals. Foodstuffs capable of giving mental abilities to a person deprived of them have not yet been found.
You can tickle yourself. You can tickle, but it won't tickle. Since the human brain is tuned to the perception of external stimuli, it perceives signals caused by the actions of the person himself less actively.
Playing chess is more difficult than looking at photographs, for example. In fact, it is much more difficult for a person to identify visual objects (especially with insufficient clarity, caused, for example, by poor lighting or poor-quality picture). In such cases, the brain "draws" the non-existent details of objects seen in passing (for example, the figure of a person you noticed at dusk on the side of the road may turn out to be a road sign on closer examination, etc.).
A person uses 10% of his brain. Studies have shown that even to perform a simple task, almost all parts of the brain are activated, and during the day a person uses almost all the available potential of this organ.
Yawning occurs only from boredom, from the desire to sleep, or from lack of sleep. It is yawning that helps a person wake up. Indeed, in the process of yawning, the windpipe expands, therefore, the lungs receive more oxygen, which, moving into the blood, invigorates us in the morning.
The hearing of blind and visually impaired people is extremely acute. Not necessary. It turns out that the blind hear weak sounds in the same way as the sighted. But people who are deprived of sight have a much better developed auditory memory, which allows them to easily navigate in space. Blind people better identify the source of sound and more easily grasp the meaning of a sentence in a foreign language.
Computer games depress brain activity, they only make you dumber. If you spend at the computer for 10-12 hours in a row, then indeed, you can achieve the mentioned effect (and it does not matter if you are playing or busy with work). It should be noted that it is computer games (not only educational, but also shooters), simulating certain situations, help to learn how to perform several tasks at the same time and quickly respond to changes in the environment.
It's so hard to forget a stupid song. It really is. The brain remembers a person's daily routine, from making coffee to the road he must take to get home. The ability to remember this sequence makes everyday human life possible. Often the brain automatically includes the heard melody in this algorithm and periodically reminds it to a person.
The larger the brain, the smarter the person. Intellectual ability does not depend on the size of the brain, but on the number of synapses (contacts between neurons).
Exercise does not affect the level of intelligence, rather the opposite. This is not true. After all, regular exercise helps to increase the number of capillaries in the brain. As a result, the blood supply to this organ improves, more oxygen, glucose and other nutrients enter the brain. It should also be mentioned that former athletes are less susceptible to Alzheimer's disease than people who have never played sports. But to achieve the aforementioned effect, exercise should last at least 30 minutes and at least three to four times a week.
Children (especially babies) who listen to Mozart's music get smarter. Of course, the positive influence of classical music on a person is a proven fact. But does this music really increase intelligence? Let's clarify: scientists at the moment do not have convincing evidence of this fact. The myth that Mozart helps make kids smarter emerged in the 1990s, after the publication of research data from college students. Students who listened to the works of Mozart for 10 minutes did better on the tasks of the test. There was no talk of children (and even more so, babies).
Artificial intelligence is just around the corner. This is fiction. After all, the brain is a morphogenetically active system, which means that the connections between neurons change all the time throughout life. There are 150 billion in the human brain, therefore, to simulate such a system, at least 150 billion processors will have to be used, between which connections are constantly re-soldered (according to certain patterns that have nothing to do with conventional mathematical algorithms). Agree - the task is quite difficult and at this stage practically insoluble.
Nicotine kills the brain. Let's clarify: nicotine has a detrimental effect on the body, but the activity of the brain, this substance, according to scientists, activates. According to experts, it is on the basis of nicotine that a medicine will be created that saves from senile dementia. Currently, drugs are being developed that mimic the effects of active ingredients of tobacco (stimulating the activity of the brain), but do not cause addiction and do not provoke diseases of the cardiovascular system, strokes, cancer, etc.
