If You Delete Your Memory, Will You Delete It?

< p > memory is sometimes a pleasant thing to delight in. Sometimes it is a trauma that is hard to die.

With the progress of scientists in the research of human brain, there may be an "unfeeling clinic", which can help you delete the memory you do not want to retain, just like the Delete key on the computer, and then you can delete the selected memory after pressing.

If we really delete those unpleasant memories, can we get rid of the shadow that has troubled us for a long time and start a new life? /p

< p > good memories. No one is willing to delete them.

Starting from the direction conducive to people's physical and mental health, scientists begin to study memory deletion from oblivion pain.

In 2011, scientists at the center for human stress research at University of Montreal, Canada, found that inhibition of glucocorticoid secretion can help patients "forget" painful memories.

The scientists took the drug for the subjects, a drug that could stop glucocorticoid secretion, and tested it with a classic story of emotional memory.

< p > scientists found that subjects who took high-dose of the drug had a significantly worse memory of negative episodes in the story, but their recollections of ordinary episodes were not affected by drugs.

More importantly, this effect on negative emotions will last longer.

Even after 4 days, the level of glucocorticoid in the medication group returned to normal, but the memory of the negative episodes was still significantly lower than that of the control group.

< /p >

< p > based on the above experimental results, the scientists concluded that controlling the secretion of glucocorticoids can reduce the impact of pain on people and do not affect the memory of normal events.

This looks like a new discovery that cheers people up, especially for a large number of patients with post-traumatic stress disorder.

But combined with more studies, we seem to know little about the real link between glucocorticoids and memory.

In 2012, the daily mail of London reported that scientists have developed a tablet that can help forget the pain. The users can forget their past trauma experience.

The report said that the risk of being questioned and criticized is that the researchers funded by the US government have been able to eliminate their painful memories by injecting certain drugs into them.

The researchers finally got the result after repeated experiments.

They say that this pill may not eradicate painful memories, but it can create optimism and safe stimulation in people's minds, so that people can easily cope with unhappy life.

< p > in fact, in addition to drugs, psychological guidance can actually forget painful things, namely selective amnesia or traumatic situational amnesia.

In addition, there are also stages of amnesia in hysteria and reactive psychosis. The duration can be from days to months, some for several years.

The forgetfulness of this psychological factor is due to the temporary inhibition of cerebral cortex function, and no organic damage. It can also fully recover.

< p > in addition to drug therapy, scientists have changed the way of thinking. They expect to find the source of human memory from genes and thus solve the problem of < a href= "http://www.91se91.com/news/index_f.asp" > delete memory < /a >.

Scientists in the United States say they have found a gene that stores memory in mice. By weakening the gene, rats can forget their painful memories.

Future research may apply to humans.

< /p >

P, a neuroscientist at the Massachusetts Institute of Technology, studied the mechanism of memory formation and made a slight electric shock on rats entering a special cage.

Within minutes, the mice soon became frightened of the special cage. When they entered the cage, they trembled all the time. By restraining the mouse's "memory gene" - Npas4, the researchers found that rats no longer dread the cage with uncomfortable feelings.

< /p >

At P, researchers also looked for ways to store memories in the brain.

When memory begins to "store" in the brain, the Npas4 gene starts, scientists say, which is the gene source that we can find related to memory at present.

< p > in mice, scientists have discovered another gene related to memory.

Scientists in the United States have proved in experiments that Tet1 gene can be used to "eliminate" the fear memory of rats.

Scientists will conduct a behavioral comparison of the Tet1 gene and the two groups of mice that have been damaged by the gene.

The two groups of mice were subjected to a slight electric shock when they were put into a cage, which made the rats feel fear about the cage.

< p > experimental results showed that when the researchers put them back in the same cage without electric shocks, the behaviors of the two groups of mice were significantly different. The mice with Tet1 genes were not afraid of the cage, because their painful memories were replaced by new memory information, while the Tet1 gene damaged mice still retained the memory of fear.

Andrei Rudenko, a scientist who participated in the study, said: "they did not learn again. They seemed to be trapped and unable to eliminate old memories."

< /p >

< p > in view of the above animal test results, scientists believe that if they can find a way to enhance the activity of Tet1 gene, it is possible to help those patients with post-traumatic stress disorder (PTSD) get rid of the shadow of painful memories.

"We believe that the most likely way to enhance Tet1 gene activity is to use some kind of medicine as a pharmacological catalyst, but we need to continue to develop and identify such a catalyst," Lu Deng Ke wrote in an e-mail to Huffington Post's science column.

P painful memories inevitably make people feel sad and sad, but proper painful memories are not necessarily bad things.

Some scientists believe that keeping proper memories of pain can help self discipline.

Remembrance of pain with the help of a professional doctor can enhance psychological resistance, just like the production of antibodies after chickenpox.

< p > and he said that he was so interested in the study of human memory because he could not forget the painful memories of his life under the Nazi regime. He said, "I can not help but relate my later interest -- the unpredictability and the continuity of people's words and deeds -- to the last year I spent in Vienna.

One of the themes of the era after the Holocaust is "never forget". It tells the future generations to be vigilant against a series of radical ideas that lead to Nazi atrocities such as anti Semitism, racial discrimination and hatred.

The scientific research I have done is to analyze and memorizing the biological basis of this motto, that is, the memory process in the brain.

< /p >

Scientists also have some concerns about the deletion of memory: People's views on what kind of people are p comes from all memory. If they erase bad memories, people may forget who they are.

Some people believe that criminals or victims who take forgotten pain pills will make it difficult to collect evidence.

< /p >

< p > anyway, scientists have been working tirelessly on the mysterious topic of memory.

Drugs inhibit pain memory, or < a href= "http://www.91se91.com/news/index_f.asp" > "eliminate" memory gene < /a >, all of which provide a direction for the scientific research of memory deletion.

With the development of science, perhaps there will be a "careless grass" appearing one day. At that time, it is to harden oneself in painful memories, or simply wipe away the trauma of the mind, and science will provide everyone with the opportunity to choose.
