Chapter 1392 Thalamus Sonic Image
The operation on the vegetative patient started the next morning. Academicians Jiang Ming and Huang Haitao also participated in the operation. It can be said that the top strength of Xiangyun Hospital was mobilized to ensure the success of the operation.However, the two academicians were willing to act as assistants and asked Chen Qun to preside over the operation.

This is Chen Qun's surgery, not the two of them.They participated in the operation only to learn and provide some experience help, because the two academicians participated, so another professor who led the brain surgery team volunteered to act as the third assistant, and only let Chen Qun retain the operation Team of nurses and other medical personnel.

This is an unprecedented experimental operation with high risks, but both the patient's family and the hospital are willing to try it once.In particular, the two family members of the patients saw that Chen Qun showed them the various combination diagrams of the patient, and they also knew that this should be the patient's only chance to get rid of the vegetative state. This kind of experimental surgery involving supercomputers is not necessarily available.

However, everyone who participated in this operation knows that the difficulty of this operation does not lie in purely technical operations, but in terms of theoretical reasoning. In fact, it is simple and straightforward. area to see which part activates the patient from a vegetative state.

This requires a theoretical level and a wealth of experience in brain science, so Jiang Ming became the first assistant without hesitation.

About 10 minutes into the operation, Chen Qun finished all the preparatory work, and a slightly beating brain ball appeared in everyone's field of vision.

Chen Qun glanced at everyone, and gave the specific direction of his operation again.

"Specifically, we stimulate the inner core of the patient's medullary plate to find a specific area where there are obvious changes in brain waves. Although the supercomputing center has done countless simulation calculations, there is a certain difference between this and the actual effect, so we It is necessary to do the things simulated by the supercomputer again, upload the actual data, and simulate new results again.”

Jiang Ming knows best that the difficulty of this operation does not lie in the operation part, but in the part of determining the location of the operation, just like finding a needle in a haystack requires luck.However, Xiao Chen never believed in luck. Instead, he made specific arrangements, divided the area to be stimulated into hundreds of areas, and established key areas and non-key areas according to the weight ratio.

Academician Jiang Da looked at the patient's brain and said something with a sigh.

"From where we stand now, the patient's brain is like a globe. Each region has its own unique language and culture, which govern different physiological functions. What we have to do is to find the correct fluctuation frequency, We then know where to place the electrodes to activate the patient."

At this time, Chen Qun looked dignified, and gave instructions to the eldest lady beside him.

"Give me electroacupuncture, first determine the brain wave signal of the thalamus!"

Following his instructions, a synthetic metal needle as thick as a hair was slowly pierced into the patient's thalamus from his hand, and as the electrodes on the electric needle were connected, several groups of Evident brainwaves and a subtle buzzing sound.As soon as it sounded, it became a rising and falling sound similar to breathing, full of vitality.

"The sonic signal of the thalamus is clear, and all the data are normal. Start the first-level voltage test and set the voltage to 1 volt!"

As the professor leading the third assistant, he immediately turned the voltage button to one volt unit on the scale in his hand. As for the two academicians who served as the first assistant and the second assistant, they were standing beside and opposite Chen Qun at this time, doing nothing He carefully raised his eyes to observe various data on more than a dozen screens.

As the voltage increased, the originally rhythmic brain wave sound wave signal immediately became a little bit hurried, and turned into the sound of brisk walking.

"The baseline map 1 of the thalamus has been determined, and the test of each area will start now! Academician Jiang, this is your field, please do it! Xiaoxin and I will compare the data!"

As Chen Qun said, he stepped aside from the position of the chief surgeon.Dongfang Wenxin beside him also left the position of the equipment nurse, and Zhao Xue, who was acting as a substitute, immediately stood up.

The following is a boring test. Jiang Ming will micro-measure the electroacupuncture needles inhaled by cow hair one by one according to the position of the three-dimensional projection icon in front, because there is a three-dimensional projection icon in front and make a record. At the same time, it is above his palm, He didn't test a single area, and there was a green light projected straight down on it, leaving a clear green light spot on the cerebral cortex to make a mark.

Looking at the changes in these details, Jiang Ming also sighed a little. If he had done this test in his own operating room, they would have used nail-sized stickers full of numbers on the brain to mark the area. , to avoid errors.

But now with computerized marking and recording, it's less traumatic to the patient, while also documenting everything more comprehensively.

In a blink of an eye, dozens of areas have been tested with electrodes, and the brain waves have also shown different fluctuations and reactions, but there is still no brain wave waveform of a normal person they need.

In other words, the tests in dozens of areas conducted in two hours had no effect.

Jiang Ming put down the electroacupuncture in his hand, and directly questioned the young couple who were still engrossed in making statistics on the computer.

"Xiao Chen, patients cannot be awakened in all areas. How about your statistics? Are there any new discoveries?"

Chen Qun replied without raising his head.

"Give us a few more minutes, Xiaoxin is changing the algorithm and counting again!"

While talking, he subconsciously glanced at the picture of the sound wave signal of the thalamus next to him. He knew that in all the tests, there was an interesting phenomenon in this sound wave signal, which is why he asked to convert brain waves into sound waves. reason.

Waiting for a few minutes is commonplace for brain surgery.After all, among all surgical operations, brain surgery is the most delicate. As long as there is no hemorrhage, everyone can perform the operation slowly, and even many operations need to be tested while performing surgery.

In the blink of an eye, a three-dimensional waveform image, or an image more like a funnel, appeared on the big screen in the operating room.Dozens of thalamic sound waves appear in different positions, and there are obvious differences in height on the plane, especially in the part close to the nucleus pulposus, the difference is smaller.

Chen Qun pointed to the picture.

"This is the sound wave image of the thalamus, which controls the brain's consciousness. We all know that this part has a special part of the brain called the pedunculopontine nucleus. From the stimulation results, we can see that the core part of the midbrain receives the least stimulation, so from various According to statistics, if we want to awaken the patient's consciousness, we need to go deep into the core of the midbrain and stimulate that part, which is the most likely to awaken the patient's consciousness."

As soon as Chen Qun finished speaking, Jiang Ming frowned.

"But we have never touched the core area. It is very likely that we will damage other parts and kill him."

"Yes, we might kill the patient, but I'm going to try to make sure that doesn't happen. We try again, and if there's no response, we stop the operation."
