Chapter 825 Not until the last moment... (for subscription)
The two hemispheres of the human cerebral cortex, in terms of functional control division, are roughly the left hemisphere governs the right half of the body, and the right hemisphere governs the left half of the body.

The longitudinal plane of each hemisphere is also divided into layers in terms of function. In principle, the upper layer controls the lower limbs, the middle layer controls the trunk, and the lower layer controls the head.

In this way, a subtle structure of upside down and left and right bifurcations is formed.

Each hemisphere is divided into several nerve centers.

Each center has its own fixed area, and the divisions are dedicated to form the differentiated and unified complex functions of the brain.

This division is mainly based on the grooves or fissures on the surface of the cerebral cortex.

On the surface of the human brain, there are grooves or fissures of different depths.And the raised part between the fissures, called the gyrus,
The brain has three large fissures, the central sulcus, the Sylvian fissure, and the parieto-occipital fissure, which divide the brain into areas of the frontal, parietal, occipital, and temporal lobes.

Within each lobe, smaller fissures divide the surface of the brain into gyri.

According to the research results of scientists, the brain gyri of the cerebral cortex are divided into dozens of functional areas, such as the mental function cortex, visual cortex, auditory cortex, body sensory cortex, language cortex and so on.

"Expert Lin, when we first targeted the cranial brain connection area and targeted the functional area stimulation, we mistakenly thought that the two babies shared the same functional area of ​​the cerebral cortex."

Jiang Hao introduced their inspection results to the dynamic diagram of the laptop, "Because after local stimulation, some response areas of the cerebral cortex of the two babies are the same."

"Later, during the re-examination, we used microcurrent needles to stimulate this overlapping cerebral cortex area, but found that only one baby's physical response could be induced."

At this time, Qi Xingfen took over the topic and said: "After repeated testing, we found that they do not share one functional area, but two functional cortical areas that overlap almost inseparably, and can even be said to be fused together. "

Lin Jie let out a soft sigh and asked, "Which functional areas are they?"

"It's these areas!"

Jiang Hao called up another schematic diagram and displayed it on the computer screen.

This schematic shows three areas highlighted in red.

One is the body's motor cortex.

This area is the center that controls the voluntary movement of the contralateral body.

It mainly receives proprioceptive impulses from contralateral skeletal muscles, tendons, and joints to sense body position, posture, and movement, and sends out fibers, the pyramidal tract, to control voluntary movements of contralateral skeletal muscles.

The second is the auditory cortex.

It accepts the nerve impulse transmitted from the ear under the action of sound, and produces the primary form of hearing, such as the perception of sound.

If the auditory areas of the two hemispheres of the brain are destroyed, even if both ears function normally, the person will completely lose hearing and become totally deaf.

The third is the visceral cortex.

Seeing this area, Lin Jie's heart sank.

This visceral cortex area is responsible for various sensory signals from internal organs.

Various activities of viscera act on the receptors on the walls of the viscera, and these receptors transmit the activities of the viscera to the cortex of the viscera. Wait for the feeling.

When the internal organs are functioning normally, the senses merge with the adult's general sense of self.

It becomes a distinct, dominant sensation only when the visceral sensation is very strong.

For example, when the stomach has a strong hunger contraction, it may be accompanied by a feeling of hunger, and the rectum and bladder are filled to a certain extent, which may cause the desire to defecate and urinate.

The visceral cortex processes the incoming impulses from the visceral organs, can cause a variety of reflex activities, and plays an extremely important role in the regulation of visceral functions.

If there is a problem with this area of ​​the cerebral cortex, the function of the internal organs will inevitably be disturbed, which will have fatal consequences.

The three of them were silent for a while, and Qi Xingfen said slowly, "Expert Lin, the motor cortex and auditory cortex are easy to talk about. If the separation fails, the two babies will be half paralyzed and one ear will lose hearing."

"If there is a problem with the separation of the visceral cortex, this..."

She glanced at Jiang Hao and said, "I suggest, save one, we have a great chance of getting a completely healthy baby."

Jiang Hao also expressed his opinion: "Dr. Lin, I agree with Dr. Qi's suggestion. In this case, the difficulty of the operation will be greatly reduced."

Lin Jie pondered for a moment, then said softly: "Continue to do further inspections. After all the inspection results come out, we will make a final decision."

"At present, these two babies, until the last moment, none of us will give up in advance..."

After Jiang Hao and Qi Xingfen left the office, Lin Jie began to study the inspection materials left by the two.

Lin Jie, immersed in his research, didn't know the passage of time until he was awakened by the ringtone of his phone.

This is a call from Meng Yang from the capital city.

Lin Jie answered the phone and asked directly, "General Meng, hello. What kind of patient is this time?"

Meng Yang's happy voice came from the phone, "Expert Lin, this is not an official business, this is a private call. In the name of a father, I would like to express my gratitude to you."

"In the name of father?"

Lin Jie asked with some incomprehension: "Is it because I refused to make an exception for your son and enroll him as a medical student?"

"It's because of my son's change."

Meng Yang sighed and said, "My son used to be pretty well-behaved."

"It's just that he has been very rebellious in the past two years. Basically, I said east, but he went west in a daze. He didn't obey my discipline at all, and he went against me everywhere."

"I didn't expect that last night, this bastard apologized to me seriously and admitted his mistake."

"His abnormal behavior directly stunned me."

"After in-depth discussions, I finally realized that it was Expert Lin's praise that made him wake up."

"Expert Lin, thank you!"

Lin Jie said modestly: "General Meng, I dare not take credit for this."

"It should be that your son is one or two years older. He has experienced a lot in life and learned to reflect."

"My words just touched him."

Meng Yang laughed and said, "Expert Lin, you deserve this thank you."

"Why did you touch him instead of someone else?"

After a pause, his voice came out from the phone again, "Expert Lin, my son is going to a cram school for the college entrance examination today."

"He decided to pass the college entrance examination and use his real strength to enter the medical school of Binhai University to prove to you his determination to study medicine."

Re-enrollment?Still applying for the Binhai University School of Medicine?

Lin Jie frowned and said, "General Meng, I need to tell you."

"The 30 people in the doctor orientation class have been recruited, and it is impossible to recruit your son to this class."

"I know, Expert Lin, you are a very principled person, and you will only give others a chance."

Lin Jie discerned Meng Yang's voice, but he didn't hear any dissatisfaction, so he continued: "I have told my son this result over and over again."

"But he said that he knew the result. After all, he was the one who squandered this rare opportunity, so he needs to take responsibility."

"He also said that he would use his performance to win another chance. After eight years of medical school, he is confident that you will change your perception of him at a certain moment, Expert Lin."

"How is it? My son's statement and determination, isn't it good?" Meng Yang said in a relieved tone!
Since Meng Yang has said so, Lin Jie has to give face.

He smiled and said, "General Meng, if your son's performance in the medical school is as good as before, I will consider accepting him as a student someday in the future."

Meng Yang chuckled and said, "Expert Lin, my son is always excellent, and he also has persistence and perseverance. Then, I will prepare a table for apprentice banquet."

Lin Jie reminded lightly: "General Meng, don't be so happy so early."

"There may be a big gap between the excellence in your eyes and the excellence in my eyes..."

After hanging up the phone, Lin Jie realized that it was also lunch time.

After he went to the hospital restaurant to deal with it casually, he came to the orthopedic laboratory in the comprehensive laboratory building of the hospital.

Here, the construction of the test prototype of the sink equipment is underway, and Lin Jie came over to take a look at the progress.

Lin Jie walked into this large room with a size of more than [-] square meters and noisy sounds. He saw a busy Lei Jun, Fang Hanrui, Huo Guangheng and other students, as well as Lei Jun's assistants, students, and several busy workers.

He also met a guy he didn't expect.

Lin Jie waved this guy over and asked, "Xue Linlin, what are you doing here instead of traveling?"

Xue Linlin laughed and said, "I'm here, doing research."

She added: "It's being studied."

Fang Hanrui came over, took off his mask, and said, "Teacher, we need an experimental sample to build this sink device."

"Xue Linlin's body shape is about the same as that of Yao Henan, and she recommended herself, so we recruited her."

Lin Jie snorted, and said, "Let me take a look at your schematic diagram."

Fang Hanrui took Lin Jie to the next room and showed a simulated dynamic picture on the computer.

This is a large sink made of high-strength resin glass, and a movable bed is placed inside.

The bed board can be raised and lowered, tilted and even erected.

"Teacher, this is just a simple animation, and various medical monitoring and auxiliary systems will be added in the future."

Fang Hanrui pointed to the schematic diagram and explained: "Through the self-supporting or tilting of the bed board, we can make the patient's head always above the water surface, and the position below the waist is always below the water surface."

"We are also planning to design a water barrier so that even if the patient's body is not in the water, the head will not be submerged."

Lin Jie nodded and said, "What about the solution to the physical problem?"

"A ureter for urination."

"As for the stool problem, teacher, can I inject nutrient solution to survive this period of time?"

Lin Jie just stared, and said, "Yao Henan's body is already very weak, but she has undergone a major operation and only received a nutrient solution? You want her to become a mummy?"

Fang Hanrui shrank his head, and said nonuo: "Then we will find another way!"

Lin Jie suggested again: "Don't forget to add some entertainment equipment to relieve the discomfort in your body and mind..."
