- I may have heard about those indirectly. One theory I heard as to why the
- older child wasn't able to develop further is that learning ability (language
- especially) drops sharply at puberty. If you are exposed to a language before
- puberty, it is easy (natural) to pick it up. If you try to learn it later
- it will be much harder. It may be because the brain is less flexible after
- that point so that more advanced learning can occur, and the basic language
- skills will never be lost. (or something like that) As to whether myelin
- has any part in that, I haven't a clue.
