calculation methods for integrate-and-fire networks
Interpret cfNetwork objects as integrate-and-fire networks - experimental.
Parameters are the same as for cfNetworks, with the addition of an integer ncell for each node, P-conn for each link, and V-reset here which applies to all cells. Each node in the cfNetwork is replaced by its corresponding ncell individual Units. Each of these makes contact with a randomly chosen fraction P-conn of the cells belonging to the target node for each of its links.
The membrane potential receives instantaneous kicks for each synaptic input and decays towards V-reset with time constant T-dec.
Cells fire when their membrane potential reaches thresh whereupon their membrane potential returns immediately to V-reset and each postsynaptic cell receives an input after the corresponding T-prop for that link.
