There are close to one million nerve fibres that connect the eyeball to the brain.

眼球和大脑有近百万纤维。

Once enough charge has accumulated, electrical signals will fire along a relay of nerve fibres until they reach the spinal cord and, eventually, the brain.

一旦积累了足够的电荷，电信号就会沿着纤维的中继发射，直到它们到脊髓，最终到大脑。

The researchers found that, whether or not players had had a recent head injury, ten of them had abnormalities in their white matter that indicated disrupted nerve fibres.

研究人员发现， 无论球员最近是否有头部受伤，其中 10 人的白质都有异常， 表纤维受损。

This is produced throughout the body at times of inflammation and makes the body more sensitive to pain by, among other things, increasing the conductivity of nerve fibres.

这会在发炎时在全身产生，并通过，等增加纤维的传导性使身体对疼痛更加敏感。

In addition to the bloodstream, one of the main pathways between the two is the vagus nerve – a long bundle of nerve fibres that stretch from the brain to the abdomen.

除了血流外， 两者的主要通路一是迷走——一束长长的纤维， 从大脑延伸到​​腹部。
