美科学家研制出遗忘药丸可删除痛苦记忆

　　ccording to the Foxnews on November 22, painful memories of people could be erased from their mind by a new medical technology, a research made by Johns Hopkins University suggests。

　　The Johns Hopkins researchers say they are working on ways to remove the proteins from the brain’s fear center, which would erase painful memories of people forever。

　　"When a traumatic event occurs, it creates a fearful memory that can last a lifetime and have a debilitating effect on a person’s life," said Richard L. Huganir, professor at the Hopkins School of Medicine。

　　Huganir and his colleges discovered a "window of vulnerability" when unique receptor proteins are created. Because the proteins are unstable, they can be easily removed with drugs or behavior therapy, ensuring the memory is eliminated forever。

　　Kate Farinholt, member of NAMI Maryland, a mental health support group, said, while it may be beneficial to erase a memory, there are still unanswered questions。
