It would depend on the neurons in question. Some neurons can fire
>300Hz and have facilitating synapses, others are hard to push past
20Hz and have rapidly depressing synapses. If you had the features of
the first, i.e. fast firing and non-depressing synapses (combined with
enough synaptic strength to make the next neuron fire, i.e. lots of
synapses or high strength synapses) your loop might work.
