美科學家研製出遺忘藥丸可刪除痛苦記憶

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。據國外網站“the Foxnews”11月22日報道，約翰•霍普金斯大學一項研究表明，一種新型藥物技術可以“抹去”人們的痛苦記憶。

約翰•霍普金斯大學的研究人員說，他們正在想法設法通過摘除大腦“恐懼”中樞的特殊蛋白質，來永久刪除人們的痛苦記憶。

霍普金斯大學醫學院教授理查德L.•胡格尼爾教授說：“當一項創傷性事件發生時，大腦裏會產生可持續一生的可怕記憶，對一個人的生活造成很壞的影響。”

胡格尼爾教授和他的同事們發現，當痛苦記憶這個“脆弱之窗”產生時，大腦裏會形成獨特的受體蛋白。由於這種蛋白非常不穩定，因此可以利用藥物和行爲治療輕鬆除去它們，永久性清除創傷性記憶。

馬里蘭心理健康援助組織的凱特•法琳霍爾特警告說，儘管消除記憶可能會帶來好處，但是目前還有很多無法回答的問題有待解決。
