It contains excitatory and inhibitory neurons with the parameters given in table 1 in the paper.

Example use:
------------

Start with "xppaut boxwell.ode" (linux, or equivalent on your platform) and select Initalconds -> (G)o. After a few seconds the inhibitory membrane voltage trajectory should appear:

screenshot Select "Xi vs t" and change VI to V. You should see the excitatory neuron voltage trajectory:

screenshot2 If you want to change the axis limits you can use Window/zoom -> Window.
