So nobody read TFA? It is from 2002.
Research since then has shown that the mouse, rat and human hippocampus (specifically the dentate gyrus, the region that if destroyed produces antereograde amnesia, like in Memento) can grow new cells that replace old ones. This also happens in the olfactory bulb - a region that helps us tell the difference between similar odors.
