Human brain is the most complex, unknown, and creatively gifted system of discovering the world. Research of this system activity involves scientists of biology, neurophysiology, psychology.

Sometimes we learn interesting facts about human brain. And here are only 10 of them.

1. Our short-term memory can store only seven objects.
People have three forms of memory: sensory, short- and long-term. Long term works like a hard drive, short-term - as a very small storage device. This short-term memory can simultaneously hold in brain only five - nine objects. Average person can simultaneously hold seven objects in memory. You can, however, train a person to handle a larger number of subjects, than nine, if you teach him combining objects into groups. In fact, most phone numbers consist of 7 digits.

2. Chartreuse is the most visible color
Yellow-green, chartreuse, is clearly in the middle of visible spectrum frequencies. Your eyes have receptors for perception of blue, green and red. But brain does not receive information about colors, it receives information about difference in light and dark, and difference between colors. As a result, brain receptors “see” exactly chartreuse color. Incidentally, this color is often used by psychologists, psychics, artists, as a sedative and at the same time most noticeable to humans.

3. Your subconscious is smarter than you
Or at least, more powerful. One of studies demonstrated a complex picture to people. They needed to point out what researchers had in mind instantly, without thinking. Most people coped with the problem instantly. Another group was suggested to think and set at the correct sector on a figure deliberately. So what? Complete failure, despite the fact they were given a few hours to solve the task.

4. Intellectual work does not tire brain
It was found that composition of blood flowing through brain during its active work remained stable, no matter how long it lasted. However, blood, taken from a vein of a man who worked all day, has a certain percentage of “fatigue toxins”. Psychiatrists found that feeling of brain fatigue is caused by our mental and emotional states.

5. Prayer has positive effect on brain
During prayer perception of information flows, bypassing mental processes and analysis, i.e. one flies away from reality. In this state (as with meditation) delta waves appear in brain, which are usually recorded in infants during first six months of their life. Perhaps this fact influenced the fact that people who worship regularly, get sick less often and recover faster.

6. Regular brain work helps preventing its disease
Studies show that regular brain work prevents development of severe disease - Alzheimer’s syndrome. Intellectual activity causes production of additional tissue, compensating ill one. At that, studying something new, and also engaging into some unusual activity arw the best ways to develop brain. Communication with people who are superior to you in intelligence also has beneficial effect on brain.

7. Human brain perceives our shadows as continued physical bodies.
Brain, identifying body position in space during its interaction with the environment, uses visual hints it receives not only from limbs, but also shadows. Shadow gives more information about body position relative to subjects, and is perceived by our brain, like its continuation.

8. For a complete brain work you need to drink enough liquid
Brain, like our whole body, consists of approximately 75% of water. Therefore, in order to keep it healthy and working, you need to drink proper amount of water. Those who are trying to lose weight using tablets and tea leading water out from body, should be prepared for the fact that simultaneously with weight loss they also lose brain efficiency. Therefore, they should do as expected - take any pills for a prescription.

9. Brain wakes longer than body
Human intellectual ability immediately after waking are much lower, than after a sleepless night, or in a state of moderate intoxication. A little warm-up for brain is very useful, except for morning breakfast and scamper, making metabolic processes in your body stronger. This means that it is not necessary to switch on a TV in the morning, you should better read something or solve a crossword puzzle.

10. Brain understands men’s speech better, than women’s
Male and female voices operate on different parts of brain. Women’s voices are more musical, sound at higher frequencies, range of frequencies is wider than in male voices. Human brain has to “decode” meaning of what a woman said, using its additional resources. By the way, people who are hearing hallucinations often hear male voices.
