Thanks for the helpful reply.  I don't really need references for the
answer you gave, but if you wanted to try to tell me that signals can
only flow in one direction, I would demand proof . . .

I've been mulling over some ideas that are based on signals being able
to flow in either direction, and I wanted to make sure that I wasn't
violating established knowledge before I go too far.

Here's a follow-up:
If synapses are, in fact, unidirectional, impulses moving in the
opposite direction can not proceed beyond the synapse, but would such an
impulse inhibit or disrupt the transmission of impulses moving in the
other direction.  That is, what happens when an antidromic signal
reaches a synapse?
