But speeds can be boosted with myelination and increased axon diameter.

但是速度可以因髓鞘化和增加轴突直径而得到提升。

The speed at which these thoughts occur is mostly consistent, with variations based on myelination and axon diameter.

这些思维的产生速度大体上是一致的，其间的区别主要基于髓鞘化和轴突直径。

Some scientists now think that this difference in myelination could be the key to uniform conduction time in the brain, and consequently, to our mental synthesis ability.

一些科学家现在认为，髓鞘形成的这种差异可能是大脑传导时间一致的关键，因此也是我们心理综合能力的关键。
