Chapter 636 Optogenetic Technology

"Patient David Stone was a marine three months ago. He was hit by a rocket while performing a mission and had a car accident, which resulted in focal damage to his nerve center. According to the results of the MRI test, He had decreased activity in the hippocampus, the part of the brain responsible for finding and retrieving old memories. This led to various damaging neurological conditions in him."

"During cognitive testing, it was found that not only did he not remember who he was, but his ability to think, speak, and speak became like that of a seven-year-old. This is an interesting case of degenerative amnesia, and we need Solve his problem on a physical level, not psychologically deny that the patient is a condition that may be faked to escape his responsibility."

When Chen Qun, Qi Hong, and Zhou Lin looked at the information in front of them, they immediately became interested. For Zhao Xue, who only knew a few words in an article, the only thing he could do was squeeze out an awkward smile. Qi Hong, who was acting as a translator, gave her a grateful look.

"MRI and CT images showed that the patient's brain did not have any major damage, nor did various nasty tumors grow, and even the common cerebral thrombosis did not appear. His symptom was a degeneration of hippocampus activity, without any The reason. It's not good!"

Qi Hong shrugged her shoulders and posed an American attitude to several colleagues present. It seemed that she was almost similar to their tour guide lady, both in tone and expression.

Chen Qun could feel the surprise and joy in her heart when she saw the top female student suddenly make a harmless joke like a young man. It seems that Dr. Dudley really came up with a genius treatment plan.

In many cases, the patient's condition is very simple, but you have used all the means, and you have tried all kinds of methods, but you can't cure the other person's cold.What frustrates you the most is that this patient who can't be cured at all can just drink a bowl of talisman water without any medical basis. The kind of collapse is simply unimaginable.

This real example was told by Huang Haitao when he was bragging. Chen Qun thought it was exaggerated, but now it seems that many medical problems are like this.You have been diagnosed with the disease, but you just can't come up with a suitable prescription to cure your disease.

Just like appendicitis and cholecystitis, which are the most difficult operations in abdominal surgery, are also the simplest operations. Some patients’ appendix and gallbladder just don’t follow the usual path, and there are all kinds of strange places.

Chen Qun looked at the information introduction on the screen and gestured with his fingers.

"So the key question of this operation is how to reactivate the cavernous neurons needed by David Stone? To help him access the memory of the past, understand who he is, why he is alive, and where? If we find If his memory is restored, will he recover?"

Qi Hong gave Chen Qun an unkind look, knowing that he deliberately joked about the three basic issues of philosophy, but in fact there was still a trace of tactical contempt.After all, everyone here knows that the current medical technology has not yet developed to this point.

This is also the most interesting part of this surgical transplant.

Zhou Lin looked at Zhao Xue weakly, as if answering Chen Qun's question, but explaining it to his girlfriend.

"I remember that the treatment of amnesia in any country now is drug treatment. The curative effect is slow and the results are unpredictable. To put it bluntly, it is just luck. I hope a miracle will happen. I suddenly understand the reason why Dr. Dudley wanted to invite Chen Qun to come over. The key. What he needs is Chen Qun's unparalleled luck to make his uncontrollable surgery predictable."

Chen Qun expressed contempt for Zhuge Liang, who was belatedly aware, and explained the reason by the way.

"I don't need to perform this operation, and even my presence doesn't matter at all. Dr. Qi, can you introduce us to the most critical factor in this case, how does Dr. Dudley treat the patient's degenerative amnesia?"

Qi Hong, who was the narrator, swiped the screen confidently, and a brand new dynamic view appeared on it.

"It's very simple and very ingenious, and after this treatment plan took shape, Dr. Dudley wrote a detailed explanation to illustrate the difference in his way of thinking. In fact, his initial idea was also a very unreliable one. The spectrum method is to use optogenetics technology for treatment."

Seeing that Chen Qun didn't speak, Zhou Lin had no choice but to act as his girlfriend's translator again.

"You mean the method of trying to use light to activate neurons in the brains of mice?"

"Yes, this whimsical idea inspired Dr. Dudley. From the successful method, he found a more convenient method, which is to implant a miniature optical circuit in his brain, and then use a computer to align the optical circuit. programmed to activate his different neurons in batches and timed to reprogram his memory."

"Wait, you mean that Dr. Dudley has mastered the functions of each area of ​​the cavernous body, and can repair and change?"

Chen Qun was really stunned this time. If the neurons of the human body can determine their functions and principles of cognition, it will be a groundbreaking discovery in any era, and it will raise human medicine to a new level.

Qi Hong gave Chen Qun a white look, and complained quietly.

"Don't pretend to be honest. It's not like you don't know all kinds of cutting-edge scientific and technological research in neurology after World War II, almost to the point of madness. All kinds of brainwashing, lie detectors and other well-known things appeared in that era Yes. So if there is enough data, doctors can omit the principle and directly use this principle to achieve a certain process. We are not completely controllable about nuclear fusion, but it does not prevent us from using this technology."

Chen Qun immediately asked another question.

"It is difficult for light to pass through the patient's brain. The hippocampus is still deep in the human brain. Is it going to be penetrated by laser?"

Seeing Chen Qun's leaping thinking without saying a word, Qi Hong is also used to it, and directly turned back.

"The question you thought of, Dr. Dudley also thought of, so he naturally thought of the photoelectric effect. If you can't use light beams, that doesn't mean you can't use electromagnetic pulses. So after more than a month of improved experiments, he sent electromagnetic pulses through Through his brain tissue, to find his memory, the effect is very remarkable."

"But we still don't know where each memory is located, how to encode it?"

"Although we don't know the correctness of each piece of specific information, we do know the approximate location. Through modern and state-of-the-art equipment and comparative tests, we can find out the specific location of some recurring memories in a period of more than a month, so that Be sure. Although this operation is not [-]% successful, it has opened a window for us to find information in the brain memory."

"This is definitely not the first time that a human neural information test has been conducted. You believe that the results will appear in more than a month."

Chen Qun raised his head and looked at the female schoolmaster with radiance.

The corners of Qi Hong's mouth twitched twice, and then fell silent for a while.

The bastard Chen Qun can always find blind spots where ordinary people don't pay attention.
