The differential equations and **V**-dependent functions are

where

and

For Figures 1-3, we use the parameters , and .
All conductances are in mS/cm and voltages in mV.
These same parameters are
used for Figures 4-6, with the following exceptions: , and . In Figures 7-8,
the parameters are as in Figures 4-6 but The current, **I**,
(in ) is
generally the only free parameter.
