most complex organ of the human body is the brain.The genius of his work exceeds the work of all computer systems together.
The human brain is a kind of command center for all of our body.He constantly receives signals from all the senses, which are the eyes, ears, tongue, nose and skin.And immediately sends orders to respond to all parts of the body.But the most unfathomable brain function is the ability to think and create, to learn, to dream and hope, sorrow and rejoice.Also the brain controls the operation of all the internal organs.Due to the brain, we can speak, hear, read.
protected this important body strong skull, consisting of thirty-eight bones connected to each other and looks like a mosaic.Scientists long been concerned by the question, how much weight the human brain.After some research, it was concluded that this body is a pinkish-gray substance weighing 1.4 kilograms, but the weight varies slightly under the influence of various factors, including aging.
The human brain consists of three main parts: the cerebrum, cerebellum and brain stem.These parts perform certain functions, and they are connected with each other closely, with responsibility for all complex life processes of the body.
The biggest part is the big brain.Its outer layer forming the so-called cortex, provides the most important process - the process of thinking.Brainstem is the internal control systems of the body, such as cardiovascular, respiratory, digestive, excretory.For posture, balance control, movement of muscles responsible cerebellum.
human brain has plasticity.This defeats any of its division, other immediately compensate for its function.
is believed that the brain is resting at night.This is misleading.The brain works a full day, but at night the intensity of his work is somewhat reduced.Therefore, its cells must constantly be enriched with oxygen and glucose.If the oxygen supply is stopped even for a few minutes, the cells begin to necrotic (die off).
known that the human brain every second handles a huge amount of impulses from the body.Our body has the property so-called filtering, the essence of which is that ninety-nine percent of unnecessary information is eliminated, resulting in brain overload released.It's no secret that there are two hemispheres - left and right.For semantic perception of words left is responsible for color perception - right.
Our brain is so constituted that it is able to not only manage the vital processes of the body, but you can train him.Training mental nature very well affect the development of memory.And so the brain could quickly solve any challenges, it needs to constantly throw new ideas, even though he is so very complex, multi-level and highly organized human body.
As mentioned above, each region of the brain has its own defined responsibilities.There are so-called sensory areas responsible for our feeling motor which controls the movement of the body, cognitive responsible for thinking, emotional, and so forth.
But our brain is designed so that at the same time the work can not engage all areas at once, or a person, as they say, simply would have gone mad.So it is quite obvious that overly active mental activity can hurt.
Mankind has long worried about the question of how much the human brain works.It turns out that the brain such greats as Pushkin and Einstein used to eleven percent, and the brain of an average person - only five to seven percent.This suggests that the brain reserves are endless, and our task is to learn how to manage the most of these stocks.
