What is the Difference between the Right Brain and Left Brain?

The left brain is the left part of the human brain organ, on the same side as the human left hand. The experiment of scanning the human brain by MRI scanner found that when completing tasks such as language and logical thinking, both the left and right brains are involved, while the left brain pays more attention to details, and the right brain pays more attention to important situations. It's the difference in the way you approach the problem, not the difference in its function itself.

Left and right brain function division is misinformation

Research in the scientific community has shown that studies have said that the division of left and right brains is a misinformation.

University of Utah scientists revealed a misinformation after analyzing more than 1,000 brains. They did not find evidence that people were inclined to use the left and right brains because all subjects used the entire brain equally throughout the experiment.

According to the traditional impression, you would think that the logical, methodical and analytical person has the left brain, while the creative and artistic person has the right brain. But this proved to be a misunderstanding.

The study's lead author, Dr. Jeff Anderson, who is responsible for functional magnetic resonance imaging neurosurgery mapping services at the University of Utah, said that there is a misconception that everything related to analytical power is limited to one side of the brain, while creativity Everything is restricted to the other side. In fact, what connects humans to both creative and analytical thinking is the connection between all brain regions.

Anderson's team looked at brain scans of subjects between the ages of 7 and 29 at rest. They studied the activity of 7,000 brain regions and the neural connections within and between these regions. They found that, on average, the neural networks and connections on both sides of the brain are basically the same.

Dr. Anderson also said that preference for certain brain areas over other areas does exist. Scientists call this a side advantage. For example, for most right-handed people, the left brain is involved in language (the right brain is also involved). But this does not mean that great writers or orators use more left brain than right brain, or more neurons on one side of the brain.

"We haven't seen a pattern in which the entire left brain network is more closely connected or the entire right brain network is more closely connected," said graduate student Jared Nelson, the study's first author.

Potential is not huge

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. ^[7]

The right brain stores the same amount of information as the left brain. The two are basically the same in morphology and structure, and the number of nerve cells and the number of synaptic contacts are also at least in the 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. ^[8]

If we can understand the left brain in depth, we can solve many brain mysteries, such as a scientific explanation of schizophrenia.

Basically the same function and structure as the left brain

A neuroscientist study from the University of Utah found that there is no dominant right brain or dominant left brain, and one side of the brain cannot dominate or affect individual personality characteristics. Researchers analyzed brain MRIs of 1011 people between the ages of 7 and 29 at rest, and monitored and compared brain activity and different brain regions. The findings show that there is no evidence that people are more inclined to use the right or left brain. Research director Dr. Jeff Anderson said: "It is certain that certain brain functions are indeed responsible for one side of the brain. For example, the left brain tends to organize language, while the right brain is more used to control attention. But it does not exist The left or right brain is more dominant. The decisive factor is the multiple connections of brain activity. " ^[9]

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. ^[10]
