NEURON DEMO FOR SIMULATING DIFFERENT CLASSES OF CORTICAL NEURONS
CNRS, UNIC (Bat-33), Avenue de la Terrasse,
91198 Gif-sur-Yvette, France
This package is running with the NEURON simulation program written by Michael
Hines and available on internet at:
The package contains mechanisms (.mod files) and programs (.oc files) needed to
simulate single-compartment models of cortical neurons. Details of the
kinetics of currents are given in:

HOW TO RUN
Use autolaunch on modeldb or:
To compile the demo, NEURON and INTERVIEWS must be installed and working on
the machine you are using. Just type "nrnivmodl" to compile the mechanisms
given in the mod files.
Then, execute the main demo program by typing:
Compile the mechanism (mod) files by using mknrndll. Then start the simulation
by clicking on mosinit.hoc in windows explorer.
back to any platform:
Once the menu and graphics interface has appeared, select a simulation from the
"Simulations of cortical cells" window. Reposition the windows to find the
Run Control window. Then click on "Init and Run" button to start the simulation...

7/11/2005 Changes added which removes electrode on subsequent simulations.
Note: 3/9/2002 Michael Hines made non-substantive changes to allow the
3 demos to run in the same NEURON process. Thus the original button panel
was replaced by a radio button panel, and any files which should only
be opened once per NEURON launch are now opened via load_file instead
of xopen. Lastly, before the gui for each demo is started the previous
gui is erased with the restart() procedure which was added to
20120109 updated SOLVE method in cadecay.mod to derivimplicit and IM.mod,
IT.mod to cnexp as per
