Hi,
I'm missing a bit of context here... Is this a mult-icompartmental
neuron or is the idea to have some effective model of back-propagation
in a single-compartment neuron? In general, the easiest way to model a
rectangular current or conductance is with a synapse with two pathways.
E.g., let's say that the target cell (or compartment) has a
(dimensionless) variable K, then the Synapses object could be something
like this:
backprop = Synapses(source, target,
on_pre={'up': 'K_post += 1', 'down': 'K_post -=1'},
delay={'up': 0.5*ms, 'down': 2.5*ms})
Hope that helps, best
Marcel
