Memories and identity are closely related—so related, in fact that one of the main reasons for R's zombie identity crisis is that he has no memories of the past. It's not as bad as being a zombie version of Memento, but it's close.

They're not eating brains because they're hungry; they're eating brains because it gives them a jolt of memory. And to a zombie, memories are life.
