Can humans one day delete or edit memories? Let's take a look at this question below, and hopefully this content will help those who need it.
How can people be sad? Because it is difficult to forget these old things that are like a lifetime ago; people have memories, including crowd memory. A famous person once said: forgetting historical time represents mutiny. But the current excellent technicality can now guarantee the precise deletion of all special memories of the crowd.
Fish memory is only seven seconds, and then the pain of the matter of rats more remember half a year; and human memory but can afford to let go, has been nagging ......... now well. Chinese scientists have long been able to the human brain is not very good memory designated deleted, and can be used in social groups, delete negative memories, leaving only the age of simple.
The sci-fi movie "Paycheck" describes a future in which we can selectively erase memories from the brain in the same way that we erase computer material. Kim. Carey and Kate Winslet starred in the Oscar-winning movie "Eternal Sunshine of the Spotless Mind", the main character found that his ex-girlfriend relied on excellent equipment to delete the unpleasant memories of the two people's past in the brain, and then he himself decided to go to the brainwashing company to wash away the memory of this section. Nowadays, the process of deleting memories will not be a science fiction movie, instead, it is a long time to move towards the actual.
Brain neuroscientists can erase long-term memories in the brains of rats without jeopardizing the brain, according to drug injections. Peking University Institute of Neuroscience Wan You researchers and Professor Yi Ming team used gene editing technology to achieve the precise deletion of special memories in the brain of test rats. The research results were recently published in Science Advances, a sub-journal of Science.
Both short-term and long-term memories can be deleted, "by injecting a drug into the brain region where memories are stored, and then erasing the rat's memory. In this way it is possible to erase long-term memories in rats."
Scientists can erase memories that have been stored for a day or even a month, just as they can erase data and information from a computer hard disk. Moreover, erasing memories from the brain does not prevent the rats from re-learning and getting the ability to work with the memories, just as a computer disk that has been restored to its factory settings can be used again.
American scientists injected a compound called "ZIP" into the hippocampus of the rat's head, weakening the intermediate contact between the body cells in the hippocampus of the rat's head, which successfully cleaned up the rat's memory, so that the test rats would not be able to bypass the rotating platform's "oscillatory zone. "
Human.
Memories in the human brain can even be divided into small segments and then added, deleted or written at will. It still sounds like fantasy, but researchers are confident that one day it will be possible to create memory-erasing drugs that actually work.
In fact, for people to "fool", scientists have long had some trial, but, said "fool" trials are mainly to better treat post-traumatic acute stress disorder (PTSD). In some clinical trials, scientists have stumbled upon a drug used to treat heart disease, "Safeguard" has a certain "forget" the actual effect. LeBron James George of the University of California has shown that the apparent state of mind - the mind's ability to forget - has a real effect. George showed that obvious states of mind - love, hate, fear, etc. - turn on work stress growth hormones (such as adrenal hormones and cortisol) stimulating the nucleus accumbens, which in turn causes faster and clearer memories of emotional instability. The active ingredient in "SafeTech" can block the action of work stress progesterone in the tonsillar nucleus, thus blocking the production of emotionally unstable memories.
The greater use of memory deletion is to lull everyone; even in the future, we can configure microbial smart bracelets, which can not only accurately detect everyone's body temperature, but also accurately detect everyone's emotions. Perhaps one day, technical has been able to accurately manipulate to only allow happy, can not be sad. To achieve a global of all happy 2.
