Chapter 1612: Will "Changing Hearts" Really Affect a Person's Character?

Upon hearing this question, everyone present was stunned for a moment, and then they all smiled.

Cheng Dongyang replied with a smile: "What you are talking about is also a common question in the field of heart transplantation. In fact, this question is very simple if you say it is simple, and it is very complicated if you say it is complex. There may even be some metaphysical factors in it. .

First of all, we all understand the structure of the heart. It is an ordinary organ, and the emotional center that can affect a person's personality is located in the cerebral cortex and has nothing to do with the heart. Therefore, changing the heart will not cause personality changes.

This is our basic understanding and the main consensus in the current academic circle.

However, research in recent years has shown that through follow-up monitoring and evaluation of many patients after heart transplant surgery, it was found that many of them had some obvious or subtle psychological and behavioral symptoms after the heart transplant surgery. Habits change.

For example, some patients clearly use their right hand to hold a pen and chopsticks, but after a heart transplant surgery, they involuntarily use their left hand, and their right hand is not used to it.

For another example, some patients will develop some mysophobia after heart transplant surgery, which the patients did not have before. After investigation, we found that the original owner of the heart in the patient had severe mysophobia.

Also, some patients are obviously not good at music, or do not like music, art, etc., but suddenly they can play the piano and sing better and better while undergoing heart transplant surgery.

So after reviewing so many cases, we found that after heart transplant surgery, there is a certain probability that patients will experience some changes in personality and behavioral habits.

There is currently no unified consensus on the reasons for this. Some experts believe that the reason why heart transplant surgery changes personality is due to organic changes.

We all know that heart transplant surgery is an extremely difficult operation. During the operation, some subtle organic changes will inevitably occur, which will cause organic lesions and further affect the cognitive development of the transplant recipient. Variety.

Some experts also believe that the emotional center of a person's personality is located in the cerebral cortex and has nothing to do with the heart. Organic changes in the heart will not cause personality changes. The reason why 'heart transplant' surgery causes personality differences may be because the 'heart transplant' surgery affects people's mentality and psychology, which leads to personality differences. This is the surgery you mentioned before. Traumatic mental illness caused by factors.

Of course, some experts believe that our current understanding of the heart is not enough. They believe that the human heart may have certain thinking or memory functions that have not been discovered by medical scientists, and that personality changes may stem from this.

It is also possible that the heart secretes a biotin or bioelectric signal through the blood, similar to the kidneys' adrenaline. It will have some impact on the human brain, causing changes in some people's personalities and behavioral habits. "

At this point, Cheng Lao looked at Wu Hao in a gentle tone and said: "Of course, these are some speculations and inferences, and there is no direct evidence to prove it. However, we cannot explain this phenomenon, so there is currently no academic research on this aspect. A unified formal understanding and statement.”

After Cheng Lao finished speaking, Professor Zheng looked at Wu Hao and everyone present and asked, "I have a question. Let's not talk about whether heart transplantation will have an impact on the personality and behavioral habits of the transplanted person. Even if it does, , this is also a problem caused by individual heart differences.

But yours is an artificial heart, and there are no individual differences, and there is no biological information about the heart donor, so it should not have an impact on the patient.

However, this problem occurred in your clinical trial patients. This does not make sense. Could it be a traumatic psychological illness caused by the surgery? "

After hearing what Professor Zheng said, an expert sitting on the other side said: "The first patient may have something to do with this. This kind of auditory hallucination is more of a psychological suggestion, so this patient always has this problem. Instead, you can hear your heart beating.

The second patient, however, did not want to talk about the impact of the surgery. There are many factors that affect mood and personality changes, including diseases and some physiological problems.

For example, if the blood flow rate is too slow and the oxygen supply to the brain is insufficient, depression and lack of interest in things and people will also occur. There may also be a lack of some hormone stimulation, which will also bring about some psychological changes in the patient. "

I rather agree with this statement.

Another expert said: "I think you should conduct a trace element examination on the patient to see if there are any related effects caused by the lack of certain trace elements.

In addition, other organs must also undergo a thorough examination so that we can know where the problem lies. "

Hearing the expert's words, Wu Hao shook his head slightly and said: "Because we are in the clinical trial stage, we will closely monitor the patients whether before or after the operation. We have conducted many systematic examinations of the whole body. This situation did not occur this time, and there will be no omissions. I can be sure of this."

"If it's not a problem with other organs or trace elements, then the problem may lie in the heart itself. Although this artificial heart can perfectly simulate the beating of a real heart, it is still very different from a real heart.

Maybe, as previously speculated, the heart will secrete a substance, which will have an impact on personality, psychology and behavioral habits. It's just that we have done very little research so far and haven't discovered it yet. "An expert from the front nodded and analyzed.

Professor Zheng nodded and said: "I think this aspect can be a subject for research. It just so happens that you are not conducting clinical trials. You can join this aspect, so that you can better evaluate the effects of your artificial heart on patients. full impact.”

Wu Hao nodded and said with a smile: "You are right, we do need to make up for the research in this area. However, we do not have specialized researchers in this area, so we hope to cooperate with some medical schools and hospital institutions to jointly Carry out research work in this area.

Professor Zheng, are you interested in this topic? "

Hearing Wu Hao's inquiry, everyone smiled and looked at Professor Zheng. Professor Zheng coughed twice in embarrassment, but did not want to refuse such an opportunity directly, and then said with a smile: "Let's come down and talk, we won't detain everyone here."

Ha ha ha ha……

Amid laughter from everyone, Cheng Lao made a concluding speech: "Actually, you don't need to worry too much about this aspect. Compared with the patient's life safety, the impact of this aspect is Very little.

So from this aspect, your artificial heart is still very worthy of recognition. "
