I can say never because I know that the brain and the mind are separate.
So, a fully copied brain does nothing but keep the body functioning.

Here is one clue:
Take a person and cut their arm, and even in the worst conditions it will heal itself.
Take a person and kill them. Then immediately put them on a respirator and get their heart beating again. They have all the vital signs of life, but if you cut their arm, and then clean the wound, sew it up, bandages and everything... the arm will never heal.
