What Are the Symptoms of Right Brain Damage?

Studies have shown that any function is involved in both the left and right brains . What enables humans to be creative and analytical is the connection between all brain regions . ^[1] The connection of all brain regions enables humans to engage in creative or logical activities. ^{[2] The} left and right brains have a functionally complementary relationship, and even if one side of the brain is removed, it can still live as usual. ^[3-4]

Right brain

(Human Organs)

The right brain stores the same amount of information as the left brain

The left and right brains are basically the same in shape and structure, and the number of nerve cells and the number of synaptic contacts are also at least in order of magnitude. No scientific experiment has shown that there is a huge difference in the information storage function between the right brain and the left brain. The statement that "the right brain stores 100,000 times the information of the left brain" is basically nonsense. ^[12]

Right brain development is not much more important than left brain development

The right brain potential is not as great as the legend, and the right brain development is not much more important than the left brain development. When a person thinks, judges, and uses language, they coordinate the left and right brains to complete it. The left and right brains need to be coordinated and balanced to develop. ^[28]

More motivated

Psychologists believe that left-handed people are under greater pressure in a world where right-handed people dominate. Pressure often becomes the driving force for motivation , which is one of the reasons why left-handed people are more motivated.

IQ has nothing to do with left and right hands

Studies have shown that there is no difference in IQ between those who are accustomed to using left and right hands . The so-called left-handed people have more developed carcasses and have proven to have no scientific evidence . The commonly used tools are designed for the right hand, which is rather inconvenient to use with the left hand, and naturally seems awkward. Whether a person is smart or not will succeed, it does not depend on whether he is used to left or right hand. This is not only related to the innate qualities, it is more determined by the efforts of the day after tomorrow.

Not all lefties are dominated by the right brain

The left brain controls the body on the right half, and the right brain controls the body on the left half. Most people in the world are used to using the right hand, which is right-handed. Lefties account for about 10% of the total population, but not all lefties are dominated by the right brain. A US statistical study shows that for language function, 95% of right-handed people are left-brained, while less than 20% of left-handed people are right-brained. Don't believe in simple pictures or quizzes on various topics. They can't determine whether a person is left-brained or right-brained. Only complex brain scanning experiments can determine which brain dominates. ^[36]

Speak Chinese more than English with right brain

In 2006, a research group led by Professor Chen Lin from the School of Life Sciences, University of Science and Technology of China, through in-depth research on how Chinese people perceive Chinese tones, proved that in the early cognitive stage of the sound about 200 milliseconds after the sound enters the ear, Chinese tones mainly depend on The right hemisphere of the brain is used for analysis and processing, just like music. Studies suggest that Chinese-speaking Chinese use the right brain more frequently than English-speaking Westerners, and that more attention should be paid to developing the right-brain potential. The findings were published in the Proceedings of the National Academy of Sciences on December 19.

It is said that the left and right hemispheres of the human brain have a division of labor when processing external sound signals. Occasionally the left brain has a slight advantage in understanding semantics, while the right brain has a slight advantage in understanding music. But what exactly determines the division of labor between the left and right brains is a problem that has long puzzled the academic community, and has formed two completely different hypotheses. The acoustic hypothesis believes that the factors determining the hemisphere dominance of the brain are the acoustic properties of the auditory signal and have nothing to do with the function of the signal; the functional hypothesis argues that the factors that determine the hemisphere dominance of the brain are the function of the auditory signal and have nothing to do with the acoustic properties of the signal .

In order to resolve the dispute between the two hypotheses, Professor Chen Lin and others cleverly used the characteristics of Chinese tones that are similar to music and also carry semantics to study the brain's early auditory cognitive processes. They found that the acoustic hypothesis was established in the early pre-attention cognitive stage, while the functional hypothesis was established in the later pre-attention cognitive stage. Based on the experimental results, they proposed a two-level auditory cognitive model that unifies the acoustic and functional hypotheses. According to this model, in the pre-attention stage, the right brain becomes the dominant hemisphere for processing Chinese tones based on the acoustic characteristics of auditory input; only at the attention stage, the left brain becomes the dominant hemisphere for processing Chinese tones according to the semantic function of auditory input.

The results of this study reveal the mechanism of how the left and right brains divide labor in language perception. ^[38]

Human evolution begins with differences in left and right brain function

According to Russian media reports, 150 years ago, experts and scholars began to study the differences between the functions of the two hemispheres of the human brain, which opened the prelude to the study of the asymmetry of the cerebral hemisphere. Now the Biophysics Laboratory of the Institute of Chemical Physics of the Russian Academy of Sciences is conducting in-depth research on the human brain.

Experts believe that human evolution began with functional differences between the hemispheres of the brain. From the evolutionary history, first of all, this phenomenon occurs in fish, and the more advanced animals, the greater the functional difference between the cerebral hemispheres.

The development of the differences between the hemispheres of the brain is also different between men and women. The differences between the two hemispheres of women are relatively small, and the differences between the brains of men and women are also the result of evolution. Biologists believe that the role of males is to defend their homes against external threats. Therefore, for male creatures, especially males, the behavior selection process is urgent when dealing with external stimuli or threats, and they must make their own decisions within a short period of time. Researchers believe that differences in cerebral hemisphere function are closely related to the optimization of decision-making processes. That is to say, when encountering danger or stimulus, for the sake of protecting the family and children, men respond faster and often have to make decisions instantly. This greatly accelerates the difference in male hemisphere function. Speed of evolution.

Of course, we cannot understand the difference between left and right brains just on the surface. There are millions of channels of information exchange between the human left and right brains, and every decision a human makes is the result of the joint efforts of the left and right brains . ^[39]
