comment In a central pattern generator based on reciprocal inhibition, how does one “side” get picked over the other to start out?
I had a feeling that that's the case. So randomly (e.g. Gaussian) distributed noise is the sole or main deciding factor here?

comment Is the energy of an action potential divided among multiple axon terminals?
Actually, I don't think the end of my comment above is all that clear. The paper I linked to reports evidence of action potentials reaching all branches of an axonal arbor in at least some neurons. Given the "all-or-nothing" nature of an axon potential, it then stands to reason that, where an action potential reaches all the branches of an axonal arbor, the energy propagating through each branch will be the same as that which propagated through the "trunk" of the axon.

comment Is the energy of an action potential divided among multiple axon terminals?
Thanks! I had looked at those articles before, but they didn't seem to say anything about whether the energy of an action potential was divided across the terminals of an axonal arbor or if the energy was "replicated" in each branch of the arbor. But in thinking about it further, since an action potential is an "all-or-nothing" event, it stands to reason that the latter possibility would be the case. Here's a paper which provides some supporting empirical evidence for this.
