First, this work needs work. The English needs to be improved before I would recommend wading into the contents deeply.
Second this assertion or citation is wrong:
>for biological neurons e.g. "it is not uncommon for axonal propagation of action potentials to happen in both directions" - suggesting they are optimized to continuously operate in multidirectional way.
What is true is that dendritic spikes can propagate bidirectionally in some neurons (but can also fade or be blocked).
What we often forget is that spikes are a kludge to enable faster INTRAcellular communication (not needed in retinal processing).
The classic action potential connects the axon hillock (the spike initiation zone) to a variable subset of responsive presynaptic sites that may or may not release neurotransmitters that may or may not modulate behaviors of neighboring processes and cells.
