The point that was just raised here is I had said before that everybody who's neurologically normal comes to acquire and learn a language.
我这里向表达的关键是,我之前说过所有神经上正常的人,都会掌握和习得一种语言
-
If you look throughout the nervous system you would find cells that look different in different regions, because of where they're situated in the brain.
