The resulting light looks less like a traditional LED and more like a computer screen that can emit a highly focused light beam.

由此产生的光看起来不像传统的LED光，而更像是可以发射高聚焦光束的计算机屏幕。

Instead, this procedure takes place in a shielded room with a large machine that emits invisible beams of light at a precise target inside the brain.

相反，这个过程是在一个屏蔽室里进行的，房间里有一台大型机器，可以向大脑内的一个精确目标发射不可见的光束。
