Is it true that the brain has a division of labor between the left and the right, each performing it

The left and right brains of human beings do not have "unique skills", but "each has its own advantages", and the left and right brains overlap and complement each other in terms of function, which determines that the left and right brains cannot be independently tested under normal circumstances.

The left and right brains of the human body are connected by the corpus callosum, communicate at any time, work as a whole, complete the mission of "win-win cooperation", and in special cases, they can achieve complementary functions.

For example, in terms of motor sensation, it has long been thought that the left and right sides of the brain are oppositely dominant. In other words, the left side of the brain dominates the right half of the body, and the right side of the brain dominates the left half of the body, but now studies have found that when the contralateral brain is damaged, the ipsilateral cerebral hemisphere compensates for the loss of function of the contralateral cerebral hemisphere and controls the body, so as to achieve normal motor activities.

In the 50s of the 20th century, Sperry, a professor at the California Institute of Technology in the United States and a famous biologist, and his students began to conduct split-brain experiments on animals, and found that when the entire connection between the left and right brains of cats was severed, these animals still lived normally. Later, they conducted an experimental study on split-brain people, that is, to cut the neural connection between the two hemispheres in patients with severe epilepsy.

It was found that the independent hemispheres have their own stream of consciousness, and two independent consciousnesses exist in parallel in the same mind, and they have their own feelings, perceptions, cognitions, learning, and memories. In other words, the left brain also has the function of the right brain, and the right brain also has the function of the left brain, but at the same time, it has its own division of labor and emphasis.

The left brain processes logical data, and the right brain creates thinking.

<> about the left and right brains of people is not "each with its own talents", but "has its own advantages, and the left and right brains from the overlapping and complementary functions, it is decided that it is not possible to do an independent left and right brain test under normal circumstances." ”

Through the corpus callosum, communicate at any time, communicate, and work as a whole, complete the mission of "win-win cooperation", and achieve complementary functions under special circumstances.

For example, when it comes to movement, it has always been thought that the left and right sides of the brain are opposite.

The left brain innervates the right hemisphere and the right brain innervates the left hemisphere, but now, studies have found that when the side of the brain is disturbed, the lateral hemisphere compensates for the lack of function of the lateral hemisphere and controls the body to achieve normal movement activities.

In other words, the left brain has the function of the right brain, and the right brain also has the function of the left brain, but at the same time, each has its own division of labor and emphasis.

The left brain is often referred to as the verbal brain and operates with words, while the right brain is called the image brain and operates with images.

1. Different functions: the left brain is responsible for language and abstract thinking, and the right brain is responsible for image and thinking, with the ability to distinguish between images, wholeness and geometric space, and the processing of complex relationships is far better than that of the left brain.

2. The control nerve is different: the right brain is connected to the nervous system of the left half of the body, which is in charge of its movement and perception, so the right brain dominates the left ear and left vision. The left side of the brain is connected to the nervous system of the right half of the body, which is responsible for its movement and perception, so the right ear and right field of vision dominate the left brain.

3. Different properties: the right brain is in charge of images and feelings, and has the ability to appreciate paintings, etc., which is called the artistic brain, and the biggest feature of the left brain is that it has a language center, which is in charge of speaking, comprehending words, numbers, composition, logic, judgment, analysis, and straight lines, so it is called the intellectual brain.

Develop left-brain skills.

It is recommended that users use their right hand more: because the right hand corresponds to the left brain, if you want to exercise the left brain, you need to use your right hand to do more things, such as writing, drawing, holding chopsticks, etc.

Don't just rely on intuition when dealing with things, the left brain corresponds to the ability to analyze rationally, so when dealing with things, you need to think more and ask a few more whys.

Learn to make a plan before doing something, and when you do something in a planned way, your thinking will become more rational and organized.

The difference between the left brain and the right brain, the masters who have achieved great things or in various fields are masters who use the right brain.

The left side of the brain pays more attention to details, while the right brain pays more attention to the big picture, and the difference between the left and right brains is the difference in the way problems are handled, not the difference in their function itself.

1. The left brain is the left part of the human brain organ, which is the same side as the left hand of the human being. Experiments on the human brain by an MRI scanner found that the left and right brains will be involved when Lao Cong completes tasks such as language and logical thinking, while the left brain pays more attention to details, and the right brain pays more attention to the big picture.

2. The right brain has a very weak bias, but not the right brain is only responsible for creativity. Studies have shown that the left and right sides of the brain are involved in any function. What enables humans to think creatively and analytically is the connection between all brain regions.

It is the connections of all brain regions that enable humans to engage in creative or logical activities. The left and right sides of the brain have complementary functions, and even if one side of the brain is removed, they can live as usual.

The brain is divided into two hemispheres, each of which has nerve centers such as motor area, somatosensory area, visual area, auditory area, and joint area. It can be seen that the two hemispheres of the brain are symmetrical.

In the operation of nerve conduction, the opposite nerve centers of the two hemispheres cooperate with each other and intersect: the management of body parts by the motor zones of the two hemispheres is crossed left and right, and upside down and upside down; The relationship between the visual area of the two hemispheres and the two eyes is as follows: the left hemisphere visual area manages the left half of the retina of both eyes, and the right hemisphere visual area manages the right half of the retina of both eyes; The auditory areas of both hemispheres share the responsibility of managing the auditory information that comes in both ears.

The joint area of the two hemispheres plays the joint function of the relevant regions of the left and right hemispheres respectively.

In terms of brain function as a whole, the two hemispheres are not independent, and there is still an interaction between them; The interaction is completed by the connection of the corpus callosum.

Under normal circumstances, the functions of the two hemispheres of the brain are divided and cooperated, and between the two hemispheres, the corpus callosum, which is made up of nerve fibers, is responsible for communicating information between the two hemispheres. If the corpus callosum is severed, the two hemispheres of the brain are separated, and the functions of each hemisphere are isolated, and the corresponding cooperation is lacking, and the behavior will be lost.

The two hemispheres of the human brain, in terms of functional division, are roughly the left hemisphere for the right half of the body, and the right hemisphere for the left hemisphere. The longitudinal surface of each hemisphere is also functionally divided into levels, in principle, the lower limbs of the upper tube, the trunk of the middle tube, and the head of the lower tube. In this way, a subtle structure of upside down and left and right bifurcation is formed.

In each hemisphere, there are several nerve centers that are divided into different centers, each of which has its own fixed area, and the divisions are responsible for the complex functions of forming the differentiation and integration of the brain. In terms of regional distribution, the two hemispheres are not identical: the Brinell and Wechsler regions are only distributed in the left hemisphere, while the other regions are found in both hemispheres.

The left brain of a person dominates the right side of the body, and the right brain dominates the left side of the body.

The left brain is the left part of the human brain, which has a language function and is good at logical reasoning, mainly storing information and knowledge obtained after birth.

The right hemisphere is the right part of the human brain, which has five senses (sight, hearing, smell, touch, and taste). The five senses of the right brain are hidden at the bottom of the right brain, which can be called the five senses of instinct, which control the autonomic nervous system and the resonance of cosmic fluctuations, etc., and are related to the subconscious. The right brain processes the received information in an instant, so it can process a large amount of information at the same time (mental arithmetic, speed reading, etc. are the expression of information processing by the right brain).

The five senses of the right brain are controlled and suppressed by the rationality of the left brain, so it is difficult to exert the underlying instincts. However, if you know how to use your right brain, you can distinguish colors by listening to sounds, or by appearing images or smelling smells. Psychologists call this condition empathesia, and that's the potential of the right brain.
