1·He observed that the axons in his samples ended in the gray matter, and that their endings were consistent with the location of dendrites.
他发现，在他的标本中，轴突最终终止于灰质，并且它们的结合位点与树突的位置相一致。
2·That it's at its best in our twenties, then slowly declines - until we are left in old age with tatters instead of dendrites in the brain and can't even remember our own name.
那种认为在我们二十多岁时达到巅峰状态，然后缓慢地下降，直到我们老的时候，我们大脑只会越用越旧，好像不是由树状的树突组成我们的大脑，而是破布组成的，甚至记不住自己的名字。
3·It is not yet clear if the new matter was comprised of new neuron formation or if they were simply dendrites (branches).
但是对于该物质是由新神经元构成还是只是树突(分支)还不清楚。
4·The axon is much longer than the dendrites and, in fact, some axons are many feet long.
轴突比树突长的多，实际上，一些轴突长达几英寸。
5·At a finer level maybe just [understanding] the sheer complexity of 100 billion neurons, each of them with 1,000 or 10,000 dendrites [connecting them to each other].
在一个好的层面或许也只能理解1000亿神经元的复杂性，它们中的每一个有1000或10000树突连接彼此。
