Zombie Science: What are Zombies scared of?

According to legend and  most zombie fiction, zombies aren't scared of anything.  Zombies don't have any conscience and they just follow some primal drive to feed.  However, in an era where voodoo zombies have been replaced by diseased zombies, anything can happen.

As a writer, I've been fascinated by what--if anything--goes on in the brains of zombies.  There's electricity crossing synapses and there's primitive movement?  What else is there?  Are there thoughts and are there memories?  If there is any consciousness at all, zombies might fear everything they are driven to do as zombies.  Can you imagine being conscious that you are about to kill and eat someone and not having any control over it?  Can you imagine knowing that you are dead? 

The quest for scientific knowledge about zombies is what fueled my short story, "Zombie Cage."  In this story, a team of scientists and security personnel land directly in the center of a zombie horde with a mission to gather everything they can about zombies.  You'll be shocked and amazed at what they learn.
