The classic HH squid axon membrane model based on:
Hodgkin, A.L., Huxley, A.F. (1952) A quantitative description of
membrane current and its application to conduction and
excitation in nerve. J. Physiol. 117: 500-544.
The gif files are copies of original fig3 and fig6. Red lines are
polylines drawn using idraw. The polylines have control points
as near as I can place them on the circles of the data. This idraw
file is then read into neuron using idraw.hoc for translating, scaling
and copying into a Vector display tool.
The raw data in the Vector display tools, fig3k.ses and fig6na.ses
are in units of mS/cm2. These curves were rescaled to S/cm2 in
the MultipleRunFitter's. The computations in the fitters differ
from the original model curves of figure 3 and 6 because the
original model curves are fits to the data for the specific axon
17 whereas the curves shown in these simulations are for the
standard hh model.
To see the simulated curves and data from a MultipleRunFitter,
click on any item in the "Generators" list of the main MulRunFitter
panel to pop up a generator viewer
(It will be called MulRunFitter Generators).
Then in the main MulRunFitter panel select "Generators/Run all".
Questions about the representation of this model in NEURON should be
