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。据国外网站“the Foxnews”11月22日报道，约翰•霍普金斯大学一项研究表明，一种新型药物技术可以“抹去”人们的痛苦记忆。

约翰•霍普金斯大学的研究人员说，他们正在想法设法通过摘除大脑“恐惧”中枢的特殊蛋白质，来永久删除人们的痛苦记忆。

霍普金斯大学医学院教授理查德L.•胡格尼尔教授说：“当一项创伤性事件发生时，大脑里会产生可持续一生的可怕记忆，对一个人的生活造成很坏的影响。”

胡格尼尔教授和他的同事们发现，当痛苦记忆这个“脆弱之窗”产生时，大脑里会形成独特的受体蛋白。由于这种蛋白非常不稳定，因此可以利用药物和行为治疗轻松除去它们，永久性清除创伤性记忆。

马里兰心理健康援助组织的凯特•法琳霍尔特警告说，尽管消除记忆可能会带来好处，但是目前还有很多无法回答的问题有待解决。
