杨鹏GRE长难句分析:such variations in size， shape，chemistry， conduction speed， excitation threshold，and the like as had been demonstrated in nerve cells remained negligible in significance for any possible correlation with the manifold dimensions of mental experience.(5)

难免类型：复杂修饰

译文：类似于这些已经被在神经细胞中证明的在大小、形状、化学过程、产生的速度、兴奋阈值及其类似的方面上所发生变化，当他们被用来与大脑的体验以可能的方式联系起来的时候，他们在重要性上仍然是微不足道的。

解释：即使是初练难免的人其实也很熟悉such thing as something这样的语言方式，可是当中间的小东西thing居然变成了一个长达十二个单词的大东西的时候，实在令人搞不清后面的as及其后的something 到底为哪方神圣。再加上以such as 为中心的长主语距离系动词remain太远，更增加了本句的难度。请读者反复阅读，直到读出这样的感觉：顺序阅读原文时，原文似乎就是几大块，就好像是such things as a remain negligible in a certain sense.
