The relationship between left handedness and brain development

It's all the same, there's no difference, it's just a habit.

The right side of the brain is relatively rotten.

Your brain is your own wisdom. Scientific studies have proven that the brain is divided into left and right hemispheres. The left hemisphere is in charge of all activities on the right side of the person, and the left hemisphere generally has functions such as language, concepts, numbers, analysis, and logical reasoning.

The right hemisphere is all the activities on the left side of the stool, and the right brain has the functions of **, painting, spatial geometry, imagination, synthesis and so on. The left and right hemispheres of the human brain are unbalanced, and the total number of people shows that the vast majority of people have a developed left brain (about half of them are more balanced). And the different levels of development of the left and right brains imply the secrets of many of your traits and talents.

Difference and function of left and right brain:

The left brain is also known as the text brain, and its main role is to process some abstract information such as words and data. The left brain has the function of abstract thinking of analysis, understanding, and judgment, and has the characteristics of logic and rationality.

The right brain, also known as the image brain, is mainly used to process some specific information such as sound and image, and has the functions of creativity, inspiration, imagination, etc., with the characteristics of perceptual and intuitive, and it focuses on processing random, imaginary, and multi-sensory image information. <>

Left-handed, after all, is in the minority, but scientists recently said that the situation in the future may be very different, as the number of left-handers is growing rapidly.

In 15 years, the number is expected to increase to 1 billion.

Statistics show that 1 in 10 people in the world are left-handed, a total of 600 million people; By 2020, the number of left-handers is expected to reach 1 billion. The Russian newspaper Pravda says that scientists now have a new theory about left-handers. Dubov, a biology professor, said twice as many left-handers were born in 2005 as there were in 1990; He believes that human beings are changing, and this is a good phenomenon, because human beings are not degrading, but becoming more perfect.

Studies have shown that left-handed people have higher IQs than right-handed people: 1 in 5 exceptional people are left-handed. Among those with hypersensory abilities, many are left-handed.

What was once considered a flaw for left-handers is now a symbol of genius. Throughout the ages, many of the great figures who have turned things around and changed history have been left-handers, and the role of left-handers in contemporary political and economic life is far higher than their proportion in the population: former Clinton of the United States, Cuban leader Fidel Castro, Queen Elizabeth II and Prince William; the well-known painter Leonardo da Vinci, comedian Chaplin, actress Marilyn Monroe; Natural scientist Albert Einstein, Microsoft founder Bill Gates, and even terror mogul Osama bin Laden are left-handed.

The fetus in the mother's body knows the future trend.

Experts have not yet given a clear explanation for the phenomenon of left-handedness, but they have found that the fetus has developed a left-handed or right-handed habit in the mother's womb. Using special ultrasound imaging techniques, they found that if the fetus was struggling to suck on the left hand, it would be left-handed in the future. Experts say that in the middle and late stages of infant brain development, there are some functional changes.

Because the right half of the brain not only controls the left hand, but also determines the person's ability to speak and write later.

Left-handed people are born with developed minds? Experts give an explanation, and the results are surprising.

Left-handed people have a more developed right brain than the average person.

I'm left-handed, little.

When my parents saw me holding chopsticks and a pen with my left hand, I forcibly corrected it, but other places where I used my hands, such as cutting vegetables with a knife, serving rice, playing basketball, playing water, etc., were still naturally left handed. Personally, I like to paint very much, I like to think crankily since I was a child, I always want to write and paint in a blank space, Van Gogh's starry sky is my favorite oil painting, always give me an illusory feeling full of endless imagination and dreams, I also like to study galaxies, I like to read 100,000 whys since I was very young, I picked the astronomical part to watch, grandma said that when I was a child, I always loved to stare at the turning wheels and always thought I was asleep,

There is a certain genetic factor to the presence of left-handedness that may be related to changes in certain genes. These studies have yet to be validated. At present, we do not know much about the neural mechanisms of left-handedness, such as what genes and what kind of environment make left-handedness.

Judging from the current understanding, it is likely to be related to the asymmetric division of labor between the left and right hemispheres during brain development, that is, the lateralization of brain function. One of the most well-known examples of lateralization of brain function is the lateralization of the language brain region: for the vast majority of people, the brain responsible for language is in the left hemisphere, while a few people have a language brain in the right hemisphere.

This may be related to the interaction between genes and the environment during brain development. There is a very interesting study that shows that there is a link between left-handedness and lateralization of language brain regions. Whether left-handed or right-handed, the vast majority of people have a language brain area in the left hemisphere.

However, it is worth noting that only 4% of right-handed people have a language brain region in the right hemisphere. In people with both hands, the figure is 15 percent. And for sittingers, 27% of people have a language brain area in the right hemisphere.

If this association is to be believed, I think left-handedness may be some kind of byproduct of lateralization of brain function. Genes that affect left-handedness may play a role in the development and lateralization of the brain, affecting the brain regions that control the left and right hands. These genetic developmental bases, combined with everyday preferences, may give rise to left-handedness. Adopt it.

Why is there a distinction between left and right withdrawals? This problem can be said to be genetic: it is either a habitual problem when you were young!
