The XPP code associated with the paper:

Vo, Bertram, Tabak, Wechselberger "Mixed Mode Oscillations as a
Mechanism for Pseudo-Plateau Bursting", Journal of Computational
Neuroscience, vol. 28, pp. 443-458, 2010.

is available at this website:

Note from the ModelDB administrator: to run with XPP version 7.0 I
found I needed to change bell=off to bell=0 on one of the last few
lines.

The model when run with parameters on line 30 changed to c=6, ga=18
produces a graph like the paper Figure 1b:

The parameter changes for the other figures are given in the
documentation at the top of the file.
