This is not a complete sentence is rather a fragment.

Recently documented examples of neurogenesis=> Giving additional information about the subject.

the production=> Subject

of new brain cells=> Describing subject further.

Recently documented examples of neurogenesis, the production of new brain cells, include the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that learn new songs.

Use of that in place of when will change the meaning of the subject.

My grammar is not good :( AjiteshArun please clear us on this above issue.

Thanks

"when" functioning as a relative pronoun in a relative clause can only take the subject of the sentence?
like in this example
Recently documented examples of neurogenesis, the production of new brain cells, include the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that learn new songs

here when cannot refer to mice, because it's not the subject, I heard that in a manhattan video but "that" can remove the ambiguity, why is that?
both "that" and "when" are relative pronouns and both are attached to "in mice" then why is it that "that" can refer to mice but not "when"?
Recently documented examples of neurogenesis, the production of new brain cells, include the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that learn new songs.

rohitchayal,
documented examples>Subject
the production of new brain cells>Appositive of neurogenesis
or>>Parallel marker
Underlined part>parallel each other
So this one is NOT sentence fragment at all!
"When" is used as "time frame".
Manhattan says: "object of preposition" can't be subject anymore. In this sentence, "mice" is object of preposition and "canaries" is also object of preposition. So they can't be subject anymore, but if the sentence permit then it can be the subject! "Mice" is not time frame, so "when" did not modify "mice" here. "That" modifies "canaries". So "canaries" is the subject of the verb "learn".
....
PS-the above explanation is just to clarify your query, but at the end of the day your sentence is not correct for the wrong use of modifier (growing), wrong use of "when" (if you put "when" here it seems that "the brain is placed in stimulating blah blah..). Also, we're talking about the "examples of neurogenesis". "The brain" and "neurons" can't be the "examples of neurogenesis" anymore!
