Scientists hope to find the delete painful memories method

[/]: Beijing-October 24, message, according to the Daily Telegraph reported, maybe soon, scientists can help people delete painful memories, this will be for those who are afraid of spiders or trying to forget the traumatic experiences of people bring hope.

Neuro-biologists believe they'll determine your goals, and then use the chemical method to erase the memory of pain and fear, but does not harm the brain. Researchers believe that this new method could help soldiers overcome the fear of war, treatment phobia patients. Even the death of their loved ones can be used to eliminate the pain.

United States Georgia Pharmaceutical University School of medicine, the brain and behavior Research Institute of Neurobiology, Joe · notestein, said: "while the memory is the best teacher, is critical to the survival and adaptation, but selectively remove some bad memories, such as trauma or unnecessary fear, can help a lot of people live a better life. Our work shows a quick erase memory without prejudice to the molecular mechanisms of brain cells. ”

The study published in the journal neuron, the research team and the Shanghai cooperation of scientists has isolated in mice, a kind of "memory molecules", this molecule removal mouse's painful memories. They are many experiments in mice through electric shock and trauma of manufacturing, the use of calcium called CamKII enzyme to remove memory in mice.

Just like the soldiers remember a patrol shot scenes, the mouse can also establish a relevant long-term pain location of emotional memory, for example, they will remember the claws wounded. However, both new and old fears can be injected into the mouse brain CamKII be erased or overwritten. Object recognition memory in a similar way, to the mouse to play several games, and then erase the memory of one of the toys. Each time this mouse will treat it as a new toy.

In the end, researchers may be made into a drug or injection injections, in memory of the requested memory of pain or fear at the dose of the drug or injection. Although this discovery is an exciting breakthrough, however, Dr. Stan stated that, in a similar method was developed for humanity before still need years because the human brain than a rat's brain is far more complex.

He also warned not to use this method to erase the pain of love. He said: "If a man love, want to eliminate the man or the romance of memory may not be a solution to the problem. ”
