With that said, Tan Zhengyue left.
Yun Hua immediately looked down at the video again.
She took it very seriously.
Tan Shaoning was helpless, went to pour a glass of water, tested the temperature of the water, and when it was just right, put it into practice, and brought it to her lips for her to drink.
"Thank you." Yun Hua really didn't look up this time.
Tan Shaoning really has nothing to do with her.
Not long after, Tan Zhengyue asked someone to bring the porridge, and told Tan Shaoning to put the porridge at a suitable temperature for her to eat before it was too hot.
Yun Hua was so focused on watching that he didn't hear anyone coming in at all.
She looked at it for a long time.
During this period, Tan Shaoning blew the porridge cold and fed it to her one bite at a time, and she didn't even want to take her eyes off the screen.
I watched for a long time.
Yun Hua didn't wake up until Ji Changqing came back and rushed in to hug her.
"mom."
"You child, you're going to kill me!" Ji Changqing was so happy that he burst into tears.
Yun Hua had no choice but to say, "You see, I'm not doing well now..."
Just as Ji Changqing came back, his aunt Ge Xuan and cousin Ji Zhiwei also came back. Cousin Ji Yan had already gone back to work and couldn't make it for the time being.
Yun Hua was not indifferent, she was just in a strange mood at the moment, and she was a little tired from so many people's concern.
"Huahua, is your head hurting again? Let's rest for a while." Tan Shaoning glanced at her and said in a timely manner.
Yun Hua also slowly reached out and pressed her head, "I'm sorry, I'm just a little out of energy."
"Then hurry up and rest for a while." Ji Changqing said quickly, his eyes still full of worry, "Don't sleep for too long this time."
Everyone in the room left, and it became quiet again.
Yun Hua frowned and said, "Bo Siqing, what's the matter? It doesn't look like amnesia..."
Not like amnesia.
This was Yun Hua's only feeling after watching the video for so long.
His behavior is very normal, and he looks like a normal person.
During the time when Yun Hua was watching the video, he was using the computer to surf the Internet, and he was very skilled in operating it. In addition, he put down the computer to pour water for himself.
There are indications that he is no different from normal people.
You must know that when he was in the underground mine, he didn't remember anything, he couldn't even open the mineral water bottle, and he didn't know how to tear the biscuit packaging bag. It was she who taught him bit by bit.
At that time, Yun Hua actually found it strange. Generally speaking, even if people have amnesia, they usually only lose the memory of some things. Basic survival skills are not missing, because things like opening bottle caps and tearing off the packaging of bread Bags and these basically belong to muscle memory, seeing actions that can be made without thinking.
So at that time, Bao Siqing completely lost all his memory and became an adult in the state of a newborn.
So what now
Yun Hua didn't understand.
The more she looked, the more confused she became, or she couldn't tell what kind of amnesia Bao Siqing was in.
"Did you find anything?" Seeing her frowning, Tan Shaoning was a little worried.
Yun Hua shook his head, "No."
"What's wrong?"
"Nowhere is right." Yun Hua was a little anxious, she looked up at Tan Shaoning, "If he lost his memory, why is he like a normal person?"
"Same as a normal person?" Tan Shaoning didn't understand what Yun Hua was worried about, "Isn't he normal just like a normal person? He just lost his memory and isn't crazy. Why do you think he should be different from a normal person?" ?”
"But..." Yun Hua looked confused and didn't know what to say, "Forget it, I'm the one who was stunned."
Tan Shaoning looked at her strangely, but did not interrupt her train of thought.
Not long after, the doctor came to examine Yun Hua again.
After the examination, she just said that she was still a little weak, and there was nothing wrong with it.
Yun Hua also happened to have questions for the doctor.
"If a person loses his memory, will he forget common-sense things? Also, will language and knowledge be forgotten along with the amnesia?" Yun Hua asked.
Although the doctor was a little surprised, he answered directly without asking any further questions: "The human brain is amazing, and memory is something that needs repeated memory to retain, otherwise, human memory will be gradually forgotten. Of course, this forgetting does not mean that these memories do not exist, but that the brain cells and nerves that store these memories become inactive because they are not frequently stimulated. If you want to find these memories, it will be more difficult.”
"Know the Ebbinghaus forgetting curve. This is a study of the laws of human memory. Even people with the best memory will inevitably forget something. This is the self-protection of our brain during the evolution process. Otherwise If a person has experienced everything he has seen, heard, felt and remembered but cannot forget, his brain will explode. Of course, except for some special cases, such as hyperamnesia."
"People with hyperamnesia, the brain will automatically remember. In fact, more than 90% of the things that we normal people encounter in a day are unnecessary to remember, but patients with hypermemoria, they will unconsciously Remembering everything, one can imagine the burden on their brains."
"It's a long way off topic, let's go back to the amnesia of normal people. Generally speaking, when we talk about amnesia, we refer to the lost long-term memory. In the case of short-term memory, it is impossible to talk about amnesia or amnesia. For example, you You memorized a text today and forgot it tomorrow, so you can’t say you lost your memory, right? There is another kind of short-term memory that doesn’t need to be mentioned. If you don’t pay attention, the short-term memory can’t be turned into short-term memory, let alone short-term memory. I will be remembered by you."
"As for the loss of long-term memory, it can be temporary, permanent, or selective. You can tell by the names of these methods."
"The storage state of memory in the brain is very complicated. The parts related to memory are the cerebral cortex, cerebellum, hippocampus, amygdala, etc. In addition, some studies have shown that the memory storage part in the brain is based on the length of time of the memory content. For example, if you recall something that happened within 12 years, the activity level of the medial temporal lobe structure of your brain will decrease, but if you recall something that happened 12 years ago, the activity level of these parts will suddenly increase... "
"What I mean by this is that the way memory is stored in the brain is elusive. We generally think that the existence of memory in the brain is a series of nerve impulse signals. The amygdala is mainly involved in the short-term memory of emotions, and the cerebellum is involved in body movements. Short-term and long-term memory, while the hippocampus is responsible for converting short-term memory into long-term memory storage. Long-term memory is also what our brain can call when needed, which is usually what we refer to as forgotten memories when we lose our memory. "
"If short-term memory does not become long-term memory through repeated strengthening, it will soon be forgotten by us, just like we memorize, you may memorize a passage in 3 minutes, you can close the book and memorize immediately Come out, but if you don’t recite it repeatedly, you may not be able to recite it after an hour.”
"It can be said that only long-term memory can be called by our brain, which is what we usually call memory. Generally speaking, amnesia refers to the loss of long-term memory."
"I've said so much just to explain that the brain is very mysterious, and human beings still know too little about the brain. Amnesia cannot be easily explained, and different situations require different analysis."
"Long-term memory is not easily lost under normal circumstances. It is usually caused by accidents or external injuries that cause long-term memory loss. This loss can be short-term, permanent, or optional."
"If there is a connection problem between the dendritic spines of neuron cells that store long-term memory, then this period of memory may be temporarily lost. When these dendritic spines are reconnected, then this lost memory will be lost. will recover."
"As for permanent amnesia, it is usually due to a brain lesion, or an accident that causes damage to a certain part of the neuron cells. Then there is no way to do it. This part of the memory no longer exists in the brain, and naturally there is no way to restore it. "
"In fact, whether it is pathological or accidental amnesia, either the brain is completely broken, or a certain area is damaged. As I said just now, memories are stored in different areas of the brain, so most amnesia people, and their amnesia is different.”
"So the damaged parts are different, and the things they forget are also different. You can't generalize."
Yun Hua was silent for a moment, then nodded, "In other words, people with amnesia may also remember what they have learned and basic common sense in life, but they can't remember what happened to them in the past?"
"Yes, this is very common in car accidents. But most of them are short-term amnesia, and the general brain damage of permanent amnesia is quite serious."
The doctor didn't finish the second half of the sentence. Generally, if the brain is severely damaged, it is not possible to talk about amnesia or amnesia. Who cares about amnesia after brain death
"Then there is another kind of selective amnesia?" Yun Hua asked again.
The doctor smiled, "Selective amnesia, in fact, should be more of a psychological problem. Selective amnesia usually occurs after a major traumatic accident, and the patient's self-response to something that is very cruel to him Stimulus protection. This incident is too exciting for the patient, and the patient cannot bear it. When a certain limit is reached, the brain will automatically judge that these things are endangering the life of the patient, and the brain will cut off this part of the memory. Events and people are all blocked... From the perspective of others, the patient has amnesia, and the patient himself really does not remember the relevant people and things. However, after psychological treatment and adjustment, such patients often able to recover."
