“神经假肢”帮助失语者用电脑“说话”

Brain implant helps man ‘speak’ through a computer

据研究人员报道,一名中风失去说话能力15年以上的男子,通过这种奇特的脑部接口,可以让他重新“开口说话”。

A brain implant has helped restore a type of speech to a man more than 15 years after a stroke robbed him of the ability to speak, researchers reported.

他们称其为神经假肢,虽然目前只有一个病人使用了这种假肢,但加州大学旧金山分校(UCSF)的研究小组希望他们的设备可以帮助其他瘫痪的人交流。

They’re calling it a neuroprosthesis, and while it’s only one patient for now, the team at the University of California, San Francisco (UCSF) hopes their device may help other paralyzed people communicate.

“据我们所知,这是第一次成功地从瘫痪和不能说话的人的大脑活动中直接解码完整的单词,”领导该研究小组的加州大学旧金山分校神经外科医生Edward Chang博士说。

“To our knowledge, this is the first successful demonstration of direct decoding of full words from the brain activity of someone who is paralyzed and cannot speak,” said Dr. Edward Chang, a neurosurgeon at UCSF who led the research team.

Chang在一份声明中说:“这表明通过利用大脑的自然语言机制,那些无法说话的人有很大希望与其他正常人恢复沟通。”

“It shows strong promise to restore communication by tapping into the brain’s natural speech machinery,” Chang said in a statement.

研究小组在一名中风患者的大脑中控制语言的区域植入了一组电极,这名患者在20岁时因中风而瘫痪,无法说话。

The team implanted an array of electrodes over the area of the brain that controls speech in a man who suffered a stroke that left him paralyzed and unable to speak at age 20.
