Scientists have zapped an electrical current to people's brains to erase distressing memories, part of an ambitious quest to better treat ailments such as mental trauma, psychiatric disorders and drug addiction. 近期研究发现，向脑中输入电流可以抹去人们不愉快的记忆。这是科学家在更好地治疗心理创伤、精神疾病和药物成瘾等疾病的研究过程中迈出的又一步。 In an experiment, patients were first shown a troubling story, in words and pictures. A week later they were reminded about it and given electroconvulsive therapy, formerly known as electroshock. That completely wiped out their recall of the distressing narrative. 在一项试验中，科学家首先藉助文字和图片向患者呈现一则令人烦恼的故事。一周之后，科学家会提醒患者回忆这个故事，然后对患者实施电休克治疗（即人们熟知的电击疗法），结果是患者完全忘记了这个痛苦的故事。 'It's a pretty strong effect. We observed it in every subject,' said Marijn Kroes, neuroscientist at Radboud University Nijmegen in the Netherlands and lead author of the study, published Sunday in the journal Nature Neuroscience. 荷兰奈梅亨拉德伯德大学(Radboud University Nijmegen)神经科学家克勒斯(Marijn Kroes)说：效果非常明显，我们在所有受试者中都观察到了这一效果。克勒斯是这篇研究论文的主笔，论文周日发表在《自然神经科学》(Nature Neuroscience)杂志上。 |
