Auto-launch from ModelDB or:

Compile the mod files with mknrndll (mswin or graphical mac) or

nrnivmodl (unix/linux)). Start the simulation by (unix/linux) typing

on the command line:

nrngui mosinit.hoc


or (mac os x) drag and dropping the mosinit.hoc file on the nrngui

icon or (mswin) double clicking on the mosinit.hoc file.


After selecting the e-type and the corresponding input current, simulation will reproduce the optimized somatic membrane potential as in fig4A (red traces) of the paper.

Example: clicking on run int cNAN 0.4 nA on the initial window should produce the following graph:
