尽管先前的研究已经证实，光的“群速度”可以超越光速c，而“信号传播速度”——光携带的信息的传播速度——不能超越光速。

Although previous studies have found that the "group velocity" of light can travel faster than c, the "signal velocity" - the speed at which information travels - cannot.

So, in order to have fast transmission you do that by transmitting electrical signals; that happens pretty quickly.

所以 为了使信号迅速地传播,细胞使用电信号,它速度非常快
