Is the right brain tube left hand and right foot?

Until now, the brain is still a black box for human beings, but with the development of science and technology and the improvement of research methods, people's understanding of the brain has also made great progress. It has been found that the left and right sides of the human brain control the parts of the body in opposite directions, that is, if you raise your left foot to shoot, then the manipulator is your right brain; Conversely, if you raise your right hand in salute, then the manipulator at this point is your left brain. Moreover, the left and right brains are also responsible for different aspects of thinking activities, the left brain is mainly responsible for logical thinking, words, numbers, analysis and other linguistic logical thinking, while the right brain is mainly responsible for color, **, imagination, daydreaming and other sensory image thinking.

However, the left and right brains are not absolutely separated, they transmit information through the corpus callosum in the middle, and what the right eye sees can be transmitted to the left hemisphere through the corpus callosum, and similarly what the left eye sees must pass through the corpus callosum to the right hemisphere (illustrated). For us normal people, even if we only see an orange in the field of vision of the left eye, the information obtained from the left eye will be entered into the right brain, and the right brain will quickly make a judgment that "it is an orange", and because the information obtained by the left eye will also be transmitted to the left brain through the corpus callosum, normal people will quickly report "it is an orange". But for those whose corpus callosum is destroyed, because the information they get in their left eye cannot be transmitted through the corpus callosum to the left side of the brain, they can't say it even though they know "that's an orange."

In addition, the localization of brain functional regions (the so-called brain functional region localization, simply put, which part of the brain or parts of the brain are controlled by your different behaviors) is becoming more and more precise.

Yes, the right brain dominates the left hand and the left foot. For example, some people have better language expression skills because the left thalamus is better developed.

The division of functions between the left and right brains.

The motor cortex is distributed at the top of the left and right hemispheres of the brain and is structurally symmetrical on both sides. Underneath the motor cortex are sensory areas, which also have symmetrical structures on both sides, which are responsible for receiving and processing various information from the movement of the bones, joints, muscles, and limbs. This area is sometimes referred to as the tactile zone.

The division of labor between motor and sensory areas of the brain is very specialized: each specific area is responsible for controlling a specific part of the body, the left half of the brain controls the right hand and right foot, and the right half of the brain controls the left side of the body.

The human brain is divided into two cerebral hemispheres, the left and the right, by the corpus callosum, which is connected by the corpus callosum, that is, the transverse nerve fibers that connect the two hemispheres. The wonder of the brain is that the two hemispheres have different divisions of labor. Professor Sperry of the United States confirmed the "left-right brain division theory" of brain asymmetry through the split brain experiment, and won the Nobel Prize in Medical Physiology in 1981.

According to this theory, the left brain of the human body innervates the nerves and organs of the right half of the body, and is the center of language comprehension, mainly completing the thinking, cognition and behavior of language, analysis, logic, and algebra. That is, the left hemisphere conducts methodical thinking, that is, logical thinking. In contrast, the right side of the brain innervates the nerves and organs of the left half of the body, and is a dumb brain without a speech center.

But the right brain has a receptive center, which is responsible for visual, synthetic, geometric, and pictorial thinking behaviors. Watching paintings, appreciating**, intuitively observing things, and looking at the big picture are all functions of the right brain. The division of labor between the left and right brains makes the function of abstract thinking more developed in the left brain, while the function of image thinking in the right brain is more developed, and the right brain plays a unique role in brain thinking.

Left brain control: language, logic, thinking, calculation, the left side of the brain innervates the motor sensation of the right upper and lower limbs; For right-handed people, the language center is generally on the left side, and the language center includes listening, speaking, reading, writing, as well as logic, mathematics, and calculation. Right Brain Control:

It dominates the motor sensation of the left limb and is also responsible for space, position, imagination, and conception. The left and right brain functions complement each other, and the difference is a matter of primary and secondary.
