PEOPLE who have had a painful experience may wish they could wipe the memory from their minds. Researchers at Johns Hopkins University, US, say that this may someday be possible.
A drug remains far off, but researchers have laid a foundation with their discovery that proteins can be removed from the brain’s fear center to cut memories forever.
Previous research had already shown that a special behavior therapy (治疗) could cut painful memories. But relapse (复发) was possible because the memory hadn’t necessarily disappeared.
By looking at that process, Richard Huganir and Roger Clem, two researchers from Johns Hopkins University, discovered a “window of vulnerability (脆弱的窗口)” when proteins are created. The proteins help signals travel within the brain as painful memories are made. Because the proteins are unstable, they can be easily removed with drugs or behavior therapy to cut memories.
Researchers used mice to find the window, but think the process would be the same in humans. They used electric shocks to make the mice fear a certain sound. The sound triggered (触发) the creation of the proteins, called calcium-permeable (钙通透性) AMPARS, which formed for a day or two in the fear centers of the mice’s brains.
The researchers are working on ways to reopen the window by recalling (唤醒) the painful memory and using drugs to remove the protein. They published their report online last month in Science Express.
Their research has drawn interest and concern from experts in mental healthcare.
Kate Farinholt, a mental health expert with the National Alliance on Mental Illness, Maryland, US, said many people suffering from a painful event might benefit from erasing a memory. “Erasing a memory and then everything bad built on that is an amazing idea, and I can see all sorts of potential ,” she said.
But there are a lot of unanswered questions, too.
“Completely deleting a memory is a little scary. How do you remove a memory without removing a part of someone’s life,” Farinholt said. “And is it best to do that, considering that people grow and learn from their experiences?”

The blockbuster film Titanic has brought millions of dollars and thousands of people to the theaters and continues to touch people today in their homes. Why is this film so successful? It is a combination of many different things. Among these are many different elements. Looking at some of these elements will show how the director and others involved were able to create an emotionally charged movie that appealed to millions.
The film uses one thematic(主题的) element called - The Truth of Human Nature. The two main characters seem to represent noble people. Most of the other characters in the film are shown as non-tolerant, rude and cold-hearted people. The element of focusing on the two main characters' love and emotion seems symbolic of an ideal state.
There are also social problems addressed. This is done in a few different ways. The most noticeable way is that the lower class people remain locked in the basement as the ship goes down. Throughout Titanic, the lighting is very important. The poor, lower class people are always shown in very warm-coloured light that gives them a sense of life and happiness. On the other hand, the rich, upper class are always shown in a flat light portraying the feeling of hardness and coldness. By using these techniques, they show the issue of class segregation(种族隔离), and they create stereotypes. The main characters are able to break free of these stereotypes and be together. This is the solution to the segregation problem.
