is available at the authors web site:

and in this ModelDB archive.

This model requires the freely available XPP which can be downloaded here:

http://www.math.pitt.edu/~bard/xpp/xpp.html

Usage:
------
When the model runs in its default configuration by starting it with a command like (linux):
xppaut ACCPersistentSpiking-Ratte2018.ode

and then selecting "Initialconds -> Go" it should display a graph similar to this:

A version of the model which graphs the voltage is supplied (ends with _v.ode):

and another (file ends with _ca.ode) which graphs calcium:

which are similar to Figure 8 A (top and middle traces on right) in the paper.
