Please really read my post before replying.
It’s not the older people that I was concerned about. I was saying if they want to compare a young adult brain to an older adult brain, they should make sure that ALL the younger people measured should be over 25, because that’s the age when the brain is fully developed and the brain’s structure is done going thru major changes.
Our brain must be similar to a computer...filing everything and then searching. The more records you put into your computer...the longer the search process....if you’ve been away from your computer.

Well, SAM the article clearly states the young adult brain 20-30 functioned the same. IOW’s in the twenty something group the two particular brain regions tended to be active at the same time.
