There is a great deal of controversy about rate of firing, from about 1
every 6 seconds to 200 per second, up to a couple of thousand at the
fastest (for cortical neurons).  By always firing I meant only that it
never rested more than a few seconds at the very most.  Yes, discrete -
absolute refractory period.​

So, again, that gives three states - not changing speed, slowing,
increasing, unlike the ANN which is set to respond (say, gives an output of
1), or not respond - an output of 0.

That is a simplified version of the neuron, I agree.  But if they are
trying to model the neuron, why not set up the three state reality?
