What does it mean when scientists say parts of your brain are "closed"?
I’ve read that children up to the age of ten are much more capable of learning languages.
That by the our late teens we’ve developed our musical tastes.
By 27 or 28 our personality is formed.
All of that is followed by the “that part of our brain closes off” kind of a statement.
Which I sort of understand. But the imagery that statement evokes is confusing to me. Especially with my limited understanding of brain functionality. I understand they are just trying to simplify things to get a point across. But is there a way to explain this phenomenon in layman’s terms from an anatomical perspective?
