#科技头条#【大脑中放置平面显微镜 有望帮助失明者恢复视力】莱斯大学的研究人员开发出一款平面显微镜FlatScope,作为高分辨率的神经接口,成为直接传递视觉和声音给大脑的替代路径。将显微镜放在大脑表面,能监测和刺激大脑皮质神经元的光信号,并将视听数据发送到大脑的传感器。当神经元数据足够大时,能恢复视觉、听觉的缺失。

Flat microscope for the brain could help restore lost eyesight

It may lead to sensors that transmit the outside world to your mind.

You'd probably prefer that doctors restore lost sight or hearing by directly repairing your eyes and ears, but Rice University is one step closer to the next best thing: transmitting info directly to your brain. It's developing a flat microscope (the creatively titled FlatScope) that sits on your brain to both monitor and trigger neurons modified to be fluorescent when active. It should not only capture much more detail than existing brain probes (the team is hoping to see "a million" neurons), but reach levels deep enough that it should shed light on how the mind processes sensory input. And that, in turn, opens the door to controlling sensory input.

FlatScope is part of a broader DARPA initiative that aims to create a high-resolution neural interface. If technologies like the microscope lead to a way to quickly interpret neuron activity, it should be possible to craft sensors that send audiovisual data to the brain and effectively take over for any missing senses. Any breakthrough on that level is a long way off (at best) when even FlatScope exists as just a prototype, but there is some hope that blindness and deafness will eventually become things of the past.
