Cool question, but it seems that if an organism HAS nerves, it
usually uses many of the same NT's that we do.  I searched that
jumbled mess in my head for an answer, and the only thing I came
up with was - get this- slime molds.  Yep.  They use cAMP to 
aggregate.  This doesn't really "count" as a NT-like function, but
I think that's the only chemical messenger they use (please check, 
though).  My two pesos...  :)
