32. Your brain cells

Wed Mar 28, 2012, 02:41 AM

Mar 2012

are the seat of your consciousness and they all don't get replaced at once in biological processes. The cells make up an integrated whole that form your consciousness. If some cells get replaced with new one through natural processes, the other cells that make up your brain are so integrated you don't lose your memory of yourself. So you are still yourself. Just like when nerve cells in your skin get replaced. It doesn't change the fact that it's still you feeling through those new nerve cells. If you replaced all your brain cells at once, as in your example, that's a different story but it's no mystery that it wouldn't be you as you seem to suggest.
