<title>Model Structure</title>
<para>
In a series of papers published in 1952, A.L. Hodgkin and A.F. Huxley presented the results of a series of experiments in which they investigated the flow of electric current through the surface membrane of the giant nerve fibre of a squid. In the summary paper of the Hodgkin and Huxley model, the authors developed a mathematical description of the behaviour of the membrane based upon these experiments, which accounts for the conduction and excitation of the fibre. The form of this description has been used as the basis for almost all other ionic current models of excitable tissues, including Purkinje fibres and cardiac atrial and ventricular muscle.

<rdf:value>This version (07) has had a stimulus protocol component added (to version 06, by James Lawson, 15/06/07) to allow the model to simulate multiple action potentials. Version 05 was created by Penny Noble of Oxford University and is known to run in COR and PCEnv. The intial voltage membrane potential was changed from 0 mV to the correct value of -75 mV. (Version 06 is the same as version 05 but has updated documentation)</rdf:value>

<rdf:value>Added stimulus protocol to allow simulation of trains of action potentials. The stimulus amplitude (20 microamperes per cm2) and duration (0.5 ms) were taken from the single stimulus in the previous version. Set a period of 200 ms (arbitrary) to allow visualisation of 3 action potentials together at a resonable zoom level.</rdf:value>
