scientists have zapped an electrical current to peoples brains to erase distressing memories,Part of an ambitious quest to better treat ailment最近的研究表明,在大脑中输出电流可以清除不无聊的人,这是科学家们在对心理后遗症、精神疾病、药物中毒等疾病更好的化疗研究过程中更进一步的结果。In an experiment,patients werefirst shown a troubling story,Inwords and pictures . a week la ter they were reminded about it and given electry在一个实验中,科学家们首先通过文章和照片给患者讲了一个令人讨厌的故事。一周后,科学家们没有警告患者想起这个故事,而是实施了电休克化疗(即熟悉的电休克疗法),患者几乎能记住这个痛的故事。

(大卫亚设,Northern Exposure(美国电视连续剧),健康)Its a pretty strong effect . we observed it in every subject,said mari jn kroes,Neuro克莱斯是这篇研究论文的主笔,论文周日在《大自然神经科学》 (Nature Neuroscience)杂志上公开。the experiment recalls the plot of the movie eternal sunshine of the spotless mind,Where an estranged couple erases memories of each other。这个实验让我想起了一部叫“eternal sunshine of the spotless mind”的电影,Science has tinkered with similar notions for years . in exposure treatment,RRS科学界也在进行相关研究多年,在暴露疗法中,医生经常以无威胁的方式将患者暴露在令人不安的事物中,付出代价,消除内心不安,逐渐减弱不安感的过程称为“消弭法”。(extinction,Extinction,Extinction,Extinction,Extinction)一些研究人员对感情药“propranolol”进行实验,希望有一天人们拥有的记忆或者吸烟者,scientists used to think that once a memory took hold in the brain,It was permanently stored and could nt be altered . people with anxiety disordered.old memory remained and could be reactivated at any time。

科学家们多次指出,如果一段记忆印在脑海中,就永远不会剩下,无法改变。过去,化疗焦虑症患者的方法是创造新的记忆来解决焦虑。但是原来的记忆依然存在,随时可以被新事物唤醒。

About a decade ago,scientists made a surprising discovery . they showed that when a lab rodent was given a reminder of some past fear,The memory大约十年前,科学家们发现了一起交通事故。当实验室里的啮齿动物警告人们回忆过去令人不安的场面时,大脑里的那个回忆不会继续呈现出不稳定的状态。如果不采取措施,其记忆就不会再次稳定,深植于大脑的过程被称为“重新牢固”。

But when certain drugs,known to interfere with the re consolidation process,were injected directly into the rodents brain,They wipedwhether it was possible to disrupt the memory-consolidation process in humans was thought to be difficult to answer because injecting drugs intttheir test subjects were 39 Patients who were undergoing electro convulsive therapy,for severe depression . in ect treatment,Patients get.触电化疗中,医生给患者注射肌肉肿胀和麻醉剂,让电流通过患者大脑的部分地区,电流引起疾病短时间发作,有助于治疗抑郁症。一些科学家推测电流改变了血流模式或大脑的新陈代谢,电流诱导大脑释放出能够对抗抑郁症的化学物质。

“patients who are treated with ect are those who typically havent responded to an array of other treatments,Including the most powerful drugs avavaualts”这项工作几乎没有完成。科学家们还不确定这种记忆读取是继续还是永久的。此外,这种技术可以有效地清除非常简单的故事记忆,但科学家需要证明他们需要记住现实世界的悲惨经历。

some researchers looking to move beyond ect are now also experimenting with propranolol,Which inhibits the actions of A hormone that enhances mm一些研究人员正在努力开发比电休克疗法更好的化学疗法,该药物由加拿大麦吉尔大学(McGill University)的神经科学家纳德尔(Karim Nader)期待明年夏天邀请大约50名后遗症后有焦虑症的患者来测试该药。
