HHsim: Graphical Hodgkin-Huxley Simulator

David S. Touretzky, Mark V. Albert, Nathaniel D. Daw, and Alok Ladsariya

HHsim is a graphical simulation of a section of excitable neuronal membrane using the Hodgkin-Huxley equations. It provides full access to the Hodgkin-Huxley parameters, membrane parameters, stimulus parameters, and ion concentrations.

In contrast with NEURON or GENESIS, which are vastly more sophisticated research tools, HHsim is simple educational software designed specifically for graduate or undergraduate neurophysiology courses. It can also be used in a neural networks course in conjunction with a lecture on how "real" neurons work. The user interface can be mastered in a couple of minutes and provides many ways for the student to experiment.

HHsim is free software distributed under the GNU General Public License. The official HHsim web site is at http://www.cs.cmu.edu/~dst/HHsim.

Online documentation including sample screen shots is available on this web site, and also included with the program when you download it. Also included are some sample exercises that use the simulator.
