Rn brain is divided into two halves, the right hemisphere is the "right brain" and the left hemisphere is the "left brain". The left and right brains divide all the structures of the brain equally. The left brain and the right brain have the same shape, but their functions are quite different. Left brain language, that is, using language to process information, converts the information that enters the brain into language to convey, which is quite time-consuming. The left brain mainly controls knowledge, judgment, thinking and so on, which is closely related to self-consciousness. The right brain has autonomy, can exert its imagination and thinking power, visualize creativity, and has excellent functions as a storyteller. Sperry's research shows that the left brain is an ordinary brain and the right brain is a genius brain. The fundamental difference between genius and ordinary people is that genius develops and utilizes the right brain consciously or unconsciously. Left brain, known as "word brain", mainly deals with abstract information such as words and data, has abstract thinking functions such as understanding, analysis and judgment, and has the characteristics of rationality and logic, so it is also called "rational brain"; The right brain is called "image brain", which deals with specific information such as sounds and images, has the functions of imagination, creation, inspiration and super-high-speed reaction (super-high-speed memory and calculation), and has the characteristics of sensibility and intuition, so it is also called "perceptual brain", mainly dealing with random, imaginary, intuitive and multi-sensory images. The right brain is a hemisphere that thinks through images, so it can turn language into images. Not only that, the right brain can also turn numbers into images and smells into images. The right brain converts everything it sees, hears and thinks into images for thinking and memory. The photographic memory speed of the right brain is much faster than that of the left brain. This is because when processing information, the left brain lexically processes the information, and the five senses need to be translated into language to convey it, so it takes time. The right brain processes the information in the image, so it is very fast and only takes a few seconds. In the advanced stage of fast reading, you also read with images, but you can't see the words in the pictures. The ancients developed the brain's function of reading pictures. Because the right brain has a preference for ultra-high-speed information input, reading a book in three minutes, that is, the so-called "wave speed reading" image reading, has brought the image memory function of the right brain to the extreme. The memory circuit of the left brain is low-speed memory, while the memory of the right brain is high-speed. The memory of the left brain is a kind of "bad root memory", while the memory of the right brain is amazing. It has the ability to "never forget". People's left brain is relatively active in dealing with simple language problems; People with developed left brains are more logical and organized in handling things. The left brain is active in social situations and is good at judging various relationships and causes and effects. Developed left brain, good at statistics and strong sense of direction. The left brain is developed and good at organization. With a developed left brain, he is good at doing technical and abstract work (such as computer programming).
