Brain stimulation can boost memory
研究发现脑部电刺激术可改善记忆力
As our brains work by firing off electrical impulses, a team at Boston University used this in order to test whether stimuli can boost one’s memory.
我们的大脑通过发送电脉冲来工作。美国波士顿大学研究团队就利用了这一原理来提高人们的记忆力。
They asked volunteers to wear a cap filled with electrodes, then used precise electrical currents to alter their brainwaves in 20-minute sessions of brain stimulation.
研究人员让志愿者戴上一顶装满电极的帽子，然后用精确的电流改变其脑电波，对大脑进行每次20分钟的无创刺激。
These took place every day for four days, and the group's ability to remember a list of words was tested.
实验连续进行了四天，然后测试了志愿者们记忆一组单词的能力。
The results, published in the journal Nature Neuroscience, showed improvements in memory lasted at least a month.
测试的结果发表在《自然-神经科学》期刊上，志愿者们记忆力改善的效果至少维持了一个月。
The researchers were able to boost volunteers’ long-term memory and also working memory, which is for the here and now.
研究人员能够提高志愿者的长期记忆，同时还改善了工作记忆，就是用于记住此时此刻发生的事情的记忆。
The researchers are now investigating whether this technology can be used in the treatment of Alzheimer's disease, when brain cells have already started dying, as well as schizophrenia and obsessive-compulsive disorder.
研究人员正在研究这项技术能否用于治疗患病时脑细胞已开始萎缩的阿尔茨海默病，以及精神分裂症和强迫症。
