This model reproduces the cardiac action potentials and pacemaker
activity of a mammalian cell of the sinoatrial node.

It is based on the paper by :

DiFrancesco D & Noble D (1985) A model of cardiac electrical activity
incorporating ionic pumps and concentration changes.
Phil. Trans. R. Soc. Lond. B 307:353-398

implemented and modified for Neuron by Francois E. Gannier

It was the first model to incorporate the external and internal
concentration changes and has been very influential in directing
modeling efforts.

To run the simulation auto-launch the model from modeldb or download
and extract the archive and then compile the mod files under:

type nrnivmodl in the DiFrancescoNoble1985 folder and then
nrngui mosinit.hoc

run mknrndll and then double click on mosinit.hoc

Drag and drop the DiFrancescoNoble1985 folder onto the mknrndll icon.  
Drag and drop the mosinit.hoc file onto the nrngui icon.

Once the simulation starts it recreates the Fig. 6 of the original
