If a machine breaks, you can fix it, even if it means replacing a part, and you can do this AFTER it’s stopped working. You can replace a part in a body to, like an organ, but only BEFORE the body stops working. Why is this? What do we lose when we die that cannot be replenished (except in the seconds/minutes after death in certain circumstances)?
In: Biology
We cannot create new brain tissue, or replace dead brain tissue. We do not understand how the brain operates well enough. Once enough living brain cells die there isn’t anything to be done.
