对，这种情况从句是不能省略主语的。因为从句主语与主句主语不同。

个人觉得，句子的主语是examples of neurogenesis. 因为如果是production, include前面为什么要有逗号？the production of new brain cells只是neurogenesis的同位语。

我觉得这道题还可以用平行的原则进行排除：

因为划线部分中间有or.

A. the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that
            

B. mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they

   虽然平行，但是example of neurogenesis...include mice...or canaries，逻辑错。

C. mice's brains that grow when they are placed in a stimulating environment or canaries' neurons that increase when they

  同B

D. the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they

E. brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that

以下是引用s7s7在2007-6-10 17:47:00的发言：

Recently documented examples of neurogenesis（神经形成）, the production of new brain cells, include
  brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that learn new songs.

绿色：主语

青色：同位语，补充说明neurogenesis

黄色：谓语

深黄：平行

That 可以修饰mice引导定语从句

而when 不行，when引导定语从句只能修饰时间。如果理解成状语从句，这种情况从句是不能省略主语的。因为从句主语与主句主语不同。

这里压根就没有逻辑主语的事，因为没有不定式或者that引导的宾语从句。

说的有道理！！when在这里没法引导定语从句，只能做状语从句

用这种方式来排除好像有点危险啊！
