Modern scientific research shows that the left and right hemispheres of the human brain have different functions. It is generally believed that the main function of the left hemisphere is logical reasoning and language expression, which is related to language, numbers, concepts and analysis. The main function of the right hemisphere is spatial and image thinking, which is embodied in music, rhythm, painting, intuition, sense of space, integrity, imagination and comprehensive power. At the same time, some studies in recent years have also found that the right hemisphere is dominant in people with left brain injury or illness, leading to the phenomenon of "Rain Man" (also known as "idiot scholar", the film Rain Man was commonly known as "Rain Man" after winning the Oscar at 1988. The medical profession calls it "scholar syndrome"). Education circles are also discussing "quality education and right brain development" and "right brain revolution". Many masters of art (such as Da? 6? 1 finch, Michelangelo, Picasso, etc. ) are used to using their left hands, so some researchers believe that right brain function leads to artistic creativity. Let's not consider scientific research for the time being, but judge only from our common sense. If we pay attention to exercising the right brain in our daily life, it will not be harmful even if it is not good for us. If we can really balance the left and right brains, exchange needed goods, learn from each other's strengths, and even maximize the efficiency of the human brain, then we will certainly gain more than just the joy of "inadvertently inserting willows into the shade." In recent years, I have gradually worked out a plan to exercise my left hand in daily life, hoping to discuss and communicate with interested colleagues to improve and activate my brain.

Write with your left hand. When watching foreign movies and listening to foreign teachers' lectures, foreigners can often be found signing, writing and writing on the blackboard with their left hands. We should also practice. Writing with left hand can be divided into two aspects. On the one hand, we write from left to right with our left hand, that is, we try to replace the function of our right hand with our left hand. Although it was ugly at first, it may not be as beautiful as when I first learned to write with my right hand. On the other hand, we write mirror words from right to left with our left hand, that is, we set up a mirror on the left or turn the paper to the other side, and look at the light and see the orthography. Personally, I guess this may be the most effective way to promote communication between the left and right brain, or it may be the real use of the right brain. When you calm down and write the mirror image easily, you will be surprised why there is such an interesting phenomenon.
