Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Mature neurons are terminally differentiated, postmitotic cells that do not undergo cell division, although new neurons can be generated from neural stem cells in specific adult brain regions.

How claims like this are judged

Judged against fact-checker rulings and reference works: claims of this kind are settled by the fact-checking record, not journal abstracts.
