但是最近科学家已经能够通过分析来自掌管语言的大脑皮层信号控制计算机光标。

But recently scientists have been able to control a computer cursor by analyzing signals from the brain area that controls speech.

目的：研究水蛭提取物对体外缺氧性新生大鼠大脑皮层神经细胞凋亡的保护作用。

Objective:To study the protective effect of leech extract on primary cultured neonate rat cerebral cortical neurons from the apoptosis caused by hypoxia in vitro.

在很长一段时间里，研究人员试图通过重现人类大脑皮层的视觉处理来绕过这个问题。

For a long time, researchers tried to get round the problem by attempting to re-create the visual processing that goes on in the human cortex.

科学家认为，这有助于刺激新的轴突的生长，重建受损区域和大脑皮层之间的连接。

Scientists think this helps stimulate new axon growth and rebuilds connections between damaged areas of the cerebral cortex.

如果你取出某人的大脑皮层，把它展平，它会有两平方英尺那么大，有点像一张漂亮的地毯。

If you took out somebody's cortex and flattened it out, it would be two feet square, sort of like a nice rug.
