my stealth fighter

Chapter 620
Hearing the "congratulations" from Lu Weijing, apart from Jiang Chanji who was mentally prepared to be calm enough, Catherine and Arabella were both stunned because they were too shocked, and Yuna was afraid of making mistakes because she had no social experience. If you don't speak, you only dare to watch words and expressions secretly, and see other people's reactions before deciding your own reaction--in terms of observing words and expressions alone, she is very similar to Yu Na.

A few seconds later, Catherine asked with a trembling voice, "Doctor Lu, what do you mean..."

"Arabella's fMRI results were beyond expectations. Her brain's visual cortex is already active, and surgery can be considered depending on the situation..."

Lu Weijing was also shocked when she saw the results of the inspection, because it was not long before the last inspection, and the last time was still a pool of stagnant water. She had reviewed relevant literature research at home and abroad before, and although there were no similar cases, all researchers Not optimistic about this possibility, even on a theoretical basis, the expected recovery time would be long, but when the fMRI images appeared on the monitor, she found that the area of ​​Arabella's visual cortex was no longer a part of her brain. It was dead gray, most of it turned into light gray, and even sporadic individual areas were slightly reddish.

She also thought that she was too tired and dazzled these days, but by calling images from other angles, several images definitely showed a light red color, unless there was something wrong with the equipment, otherwise it indicated Arabella's brain The visual cortex became active, further explaining that Arabella's optic nerve has changed from a dead end to a winding path of thorns, and electrical signal feedback is transmitted to the brain through the optic nerve, but because Arabella's eyes cannot see light, the "content" of the electrical signal "It's also pure darkness, which means that Arabella's cerebral cortex will not be too active. Who would feel excited when seeing the darkness in front of them?The brain also loses interest.

Catherine's weak body seemed to be reinvigorated, jumping excitedly, but Arabella's body went limp and almost passed out, so everyone hurried to support her.

Fortunately, Arabella was fine, she just couldn't bear the sudden great happiness, her mind buzzed, and her body was on the verge of collapse.

"Doctor Lu, is it true? You didn't see the joke, did you?" Catherine pinched her thigh to confirm, it would be too bad if she found out that this was a dream.

"Really, I never joke around at work." Lu Weijing was also very happy for Arabella, but she held back in her excitement because a bigger challenge was yet to come.

"Did you hear that? Arabella! Your eyes can finally see the light!" Catherine cried with joy as she hugged her sister, looked up at the ceiling, and kept praising the greatness of the Lord.

"Catherine, I'm so happy! Woohoo..." Arabella cried even more, with a thousand words in her heart but couldn't say anything, which made Yuna cry too.

"Such a good thing, we should tell everyone quickly." Jiang Chanji suggested.

He sent a group message on his mobile phone, and everyone who knew Arabella was notified, and even Leila sent "Congratulations".

In fact, this news has already spread among the nurses in a small range, and then it has been spread to ten or ten, and even some teachers have heard about it. After all, who doesn't like the little angel Arabella.

After the dean changed the medicine and bandages, he was pushed out of the sterile room. After hearing the news, he felt relieved that Arabella could pass the Lord's trial. Muttering prayers.

Lu Weijing waited for their excitement to subside a little, and explained them in detail in as simple a language as possible with fMRI images.

"So, surgery is about to be put on the agenda." Jiang Chanji said.

"Yes, there are two options now. One is to be conservative. Michelle will continue to stimulate the optic nerve and wait for the further development of the optic nerve, but this will not be able to further stimulate the cerebral cortex. The second is to perform eye surgery as soon as possible. When the eyes can see this colorful world, it is more effective than Michelle simply stimulating with photons." Lu Weijing explained.

Michelle was still on the top of the building at this time, and didn’t know the good news. She used photons to write on the retinas of other people, and the writing was all white without any color. She used photons to stimulate Arabella’s eyes Probably the same, no matter how powerful the photons she emits are, the number is limited, and everything seen by normal people's eyes is full of photons.

In addition, Lu Weijing also vaccinated them in advance, telling the most likely situation after Arabella's eyes see the light.

Arabella is congenitally blind, which is commonly known as "blind in the womb". It does not mean that simply curing her eyes will make her look like a normal person. The bigger problem is her brain, which cannot understand the world she sees. It takes a long time to adapt and learn.

To give the simplest example, the world seen by human eyes is actually upside down, but since infancy, the CPU of the brain has learned to process the image and flip the image upside down, but Arabella has never experienced it At this stage, when she first sees the light, the world she sees will be...extremely abnormal and weird, like everyone is walking on the ceiling, but where she is standing is the blue sky, and she will be sure when the time comes I dare not even walk, and I will bump into obstacles as soon as I take a step, and I will face many inconveniences in my daily life.

In addition, the two eyes transmit two independent image streams, and the brain also learns to combine the image streams in infancy to form a complete world. Not only that, each eye sees a plane, and the two The images seen by the eyes are superimposed to produce a three-dimensional sense and a distinction between distance and nearness. However, in the early days of Arabella seeing the light, the world will be split in two in her eyes, and there is no sense of three-dimensionality. There will be serious errors in the judgment of space and distance.

Jiang Chanji and the others looked at each other in dismay, everyone's feeling was unimaginable, they didn't expect that the seemingly simple "seeing things" is actually such a complicated and magical thing.

It's not what they and all laymen imagined. After Arabella saw the light, she immediately became intoxicated with this beautiful world, no different from normal people... It's not like this at all. If it wasn't for Lu Weijing's psychological construction first, Arabella would only tremble with fright at the weird world she saw. In extreme cases, if the patient was psychologically fragile, she might even goug her own eyes.

"So, it is very lucky that human beings do not have memories of infancy." Lu Weijing said, "If there are memories in infancy, it will probably become a nightmare for life. You can't imagine the world you saw in infancy. How terrifying, although this is due to the lack of perfect brain development in infancy, is it not the self-protection learned by human beings in the evolution process?"

Jiang Chanji recalled that he had read some online novels in which the soul of the protagonist was put on the body of a baby who was several months old, and he was not frightened mad by the world in front of him. It was a human miracle.

Catherine and the others seem to be listening to the Arabian Nights. After listening to it, they have only one conclusion, that is, they can only rely on Lu Weijing's follow-up guidance, especially in the early days when Arabella can see the light. In the hospital, not anywhere else.

"Whether it's stimulating the secondary development of the optic nerve or eye surgery, these are just equivalent to repairing your 'hardware', and your brain is not ready for the 'software' upgrade, but the brain is very smart, although it will There are various inconveniences, but as long as you can persevere with a firm will and work hard to adapt, one day you will see the same world as normal people, don’t close your eyes because of fear, and rely on hearing to recognize the world again.” Lu Wei Jing concluded that after all, in the fMRI images, Arabella's auditory-related cerebral cortex is too active, and she may shrink back due to the difficulties she encountered in the early stage and rely on hearing again.

"Thank you, Doctor Lu, we will definitely obey your arrangement. We are confident to overcome all difficulties and pass the trials God has given us, right, Arabella?" Catherine said, holding her sister's hand.

"Yes! I am also confident." Arabella nodded excitedly.

"Great!" Yuna was sincerely happy for them.

"The next thing... I have to make good arrangements. I also need to discuss with other teachers and consult with ophthalmologists from all over the world through online video. I will notify you when the arrangements are made. You will continue the previous treatment for the time being." Lu Wei Jing was also excited about facing a novel and unprecedented challenge, and the fatigue of the past few days was swept away.

The two sisters kept nodding, not knowing what words to use to express their gratitude.

"Senior is really amazing!" Yuna said to Jiang Chanji in admiration, "If senior hadn't insisted on asking, I'm afraid Arabella would have to wait a long time to know the good news!"

"That's right, why did you think that Arabella's eyes have improved?" The sisters thought about the previous events. At that time, they felt that Jiang Chanji's attitude and tone seemed to be different from usual. At this time, it was confirmed by the results. It was as if he had foreseen what would happen next.

Jiang Chan thoughtfully said, where is my strength?Obviously Yuna is amazing, and her blessing is a miracle in this field related to human health.

In front of Arabella, he did not dare to lie, and pretended to be mysterious and said: "How should I put it, there is a premonition in the dark, I have a strong feeling that Arabella has noble people to help, the situation is certain It has quietly improved."

Arabella heard that he was not lying, but she thought that the noble person he mentioned was Lu Weijing or Michelle. No one would have thought that the so-called noble person would be Yuna, and Yuna herself did not dare to think so.

Catherine kept muttering in her heart, Jiang Chanji had activated the holy sword again and had such an accurate hunch, couldn't it be someone like a prophet?
