The weight of the human brain only about 1,400 grams, it is to control all acts, thinking of the centre, it is what kind of magic structure » It is how to command the human body » The left brain and right brain division of the difference »
All human behavior, Hi, anger, sorrow, emotional music, and all of science, technology, literature, music discovery, invention, creation and creativity, are derived from human brain smart. The human brain known as the human body in the most complex and most difficult organs.
What is the human brain, the brain known as the outer cerebral cortex, there are many winding above the fold, medicine called groove back. Most of the activities of the brain are in the cerebral cortex, which is human thinking production line.
Cerebral cortex have different functional area, such as frontal in charge of people's personality, behavior and emotion, can distinguish between right and wrong and abstract thinking; parietal and acumen and activities closely related to the limbs, but also control the words and understand The ability of language; occipital control vision; temporal is responsible for hearing, along with short-term memory.
From the elements, the human brain is about 80% water, the rest is physiological and biochemical structure. Because the brain during thinking all the time , it is also the energy consumption of staggering. A weight of 70 kilograms, only to the brain weight of about 2 percent, but they consume 25 percent of the body of oxygen and carbohydrates.
Of course, the human brain to achieve its power of the basis of the human brain or nerve cells. People born with about 100 billion nerve cells , if they will line a length of up to 48,000 km. Each neurons contain will be sent to other neurons, they like baseball pitcher, will contain all kinds of physical information neurotransmitter communicated to other neurons. Each nerve cell is the most simple of the completion of the work, but when the 100 billion nerve cells begin work in an orderly manner, they produced a complex, rich sense and wisdom.
Left and right division of labour in their own awareness about the brain differences between the hemispheres on the issue of human spent a full 200 years. Scientists around the brain really established a new division of the concept, which started in the 1950s. At that time, biologists Sperry in the United States cut off experimental animals and in patients with severe epilepsy between the left and right brain nerve links found, independent of the hemisphere has its own stream of consciousness, in the same sense of independence in the minds of two parallel existence They have their own sense of perception, cognition, learning and memory, and so on. In other words, the left brain also has the function of the brain, right brain also has left brain function, but each division and focus on it.
Well, this division of labor and focus on concrete manifestation of what is in »
If the image is painted, the left brain is like a family eloquence and scientists, be good at language and logic analysis, good at abstract thinking and complex, but stereotypes, lack of humor and rich emotion; right brain is like an artist, than non-language The image of thinking and intuition, music, art, dance and other arts activities are extraordinary sentiment, and Bushan rhetoric, but full of passion and creativity, feeling rich, humorous, human touch.
Daily life, most people use the left brain is, again called modern brain of information is derived from the brain through the left side repeatedly enhanced, and our ancestors experienced by people and events after the enrichment Genetic things down, to be known as ancestral brain.
Compared to left and right brain, right brain in a weak position, only the left brain of excitement calm down, the brain will perform the opportunity. But the brain store the information contained 500 million years to the people and events experienced by their ancestors, their potential left brain equivalent of 100,000 times. Therefore, scientists believe that the development of intelligent first task is to explore the potential of the brain.
