Life, there are always some fragments or some people, recall, let us heartache, how to forget a person? It has always been the subject of the writers and inkers.
Su Shi said: Ten years of life and death are two unknowns. Don't think about it, it's unforgettable;
Bai Juyi said: The heavens and the earth are long and sometimes end, and this hatred has no end.
In short, it is impossible to forget.
So Huang Yaoshi found something: there is a kind of wine, called "drunken life and dream death", after drinking it, you can forget everything. It looks the same as the water of forgetting love.
Well, the top is actually paving. Is there really no way to erase the memory? In fact, there are still some, that is, memory resection. Today, we will talk about memory resection.
01, the discovery of memory areas
———————————
In the era of classical biology, scientists have made many amazing experiments.
The concept evolved from Pavlov's dogs to 10% brain use to complete brain use
From the whole brain concept to the functional partitioning of the brain, the memory area is also discovered at this time.
So scientists began to think of memory resection technology.
I believe that people who have seen the planet of the apes know that in that movie, the apes performed memory resection surgery for humans, which directly erased all human memories.
Yes, this is the original medical method, clearing the memory, just destroying the memory area.
02, memory resection techniques
Henry Molaison (H.M._Baidu Encyclopedia), known as the most important patient in the history of neuroscience, underwent surgery for epilepsy and was unable to form new memories after the medial temporal lobe area was removed, including the amygdala, hippocampus, parahius recortex, endotral cortex, and peristalcoccal cortex. Because his malfunctioning brain parts are critical, he has attracted much attention, and the only occupation before his death is.M that of a patient, and after his death, he enjoyed the same treatment as Einstein - dissecting the brain for analysis. The entire process of brain slicing was broadcast on the internet, and more than 400,000 people around the world watched the live broadcast during the 3-day live broadcast. At the height of the ratings, 18,000 people watched at the same time. So the memory is gone
However, the above methods, simple and crude, cannot meet everyone's needs, because what we need is not like Alzheimer's disease, forgetting everything and becoming even unknown to our relatives.
What we need is memories that can be specific, excised, and retained others. The difference between excision and purging
Is it feasible?
03, fixed point to eliminate part of the memory
In fact, as early as 1968, the famous psychologist Donald Lewis found that an electric shock to the brain of mice could erase the mice's memories of certain "unpleasant events" they had experienced.
Subsequent experiments can make people's memories blurred by repeated therapy or by injecting certain drugs, such as propranolol, into the brain.
今天介绍一篇文章，Kroes M C W, Tendolkar I, van Wingen G A, et al. An electroconvulsive therapy procedure impairs reconsolidation of episodic memories in humans[J]. Nature Neuroscience, 2014, 17(2): 204-206.
In this article, the authors take an electrotherapy method, electroconvulsive therapy (ECT), which allows for "targeted elimination" of some memories.
Briefly introduce the method: first show the patient two slides telling the story of the pain, let them have memories, then let them recall, and perform electric shock treatment at the time of recall, as a result, these people have less and less memory, and even finally completely forget this content.
This is the result of processing
Well, with this method, the memory was successfully cleared.
So, it seems, forget, is not impossible.
Of course, although this technology is currently used in clinical practice, most countries have not mastered this technology. So, still have to wait.
In addition, when you are shocked, you must be recalling this matter, otherwise you cannot activate the corresponding neural network of this memory. Otherwise, it will affect the pond fish.
